Abstract:

The contamination of freshwater resources with anthropogenic pollutant is a growing concern of interest because safe and readily available is a need for human. The situation is particularly alarming in developing countries where most rivers and lakes are receiving urban and hospital wastewater without any prior treatment. Furthermore, hospital effluents are known to play a major role in the emergence and the spread of antibiotic resistance genes (ARGs) because they discharge a high rate of antibiotic resistant bacteria (ARBs) in a highly selective environment. Cumulative with the knowledge gaps in antibiotic prescription and the free access to last resort antibiotics, under-developing countries may represent a broth culture to antibiotic resistance emergence, maintenance and dissemination. In this study, we investigate the contamination of sediment and the resistance profile of extending-spectra β-lactamase E. coli (ESBLECs) isolated from 4 urban river subjected to hospital outlet pipes (HOP) discharge in order to determine the effect of HOP discharge on urban river quality and the pattern of antibiotic resistance dissemination. ARGs (blaTEM, blaCTX-M, blaSHV and aadA) and selected bacterial species (i.e E.coli, Enterococcus, Pseudomonas spp.) where quantified in sediments using quantitative PCR (qPCR), toxic metals content were quantified by ICP-MS, and ESBLECs isolates where subjected to pulse-field electrophoresis to assess their clonality and characterized for their resistance to metal and β-lactams resistance. The results highlight the great concentration of toxic metals in sediments (47.87 (Cr), 204 (Cu), 1077 (Zn), 2.07 (Cd), 124.40 (Pb) and 3.94 (Hg), in mg.kg-1 at the HOP reject point), and the high content of FIB and ARGs copy number in all sampling sites including control site and downstream the HOP discharge indicating that hospital effluents are not an exclusive source of the biological contaminant entering the urban rivers. The analysis of ESBLECs profile showed the high diversity of clones disseminated in rivers (150 isolates, 69 pulsotypes), a global resistance to Zn, Cu, Ni and Pb and a high resistance profile against β-lactams (100% resistant to CFM, CEC, ATM, AMP, FEP, CXM, CTX, PRL; 60% to SAM and 37% intermediate to MEM). These findings indicates the human and environmental potential risk link to exposure to these contaminants and the need of developing strategies to limit the spread of these emerging contaminant.

Abstract:

The integrated management of media based (both water and air) pollutants is the vital at current as the management and legalization of individual pollutant is very difficult. Integration of various environmental aspects associated with activities of production processes is one of the challenges in industrial sectors. It is of vital concern to find the scientific way of integration of media based pollutants for today. Based on amount and kind of media based pollutants, Integrated Environmental Performance Score (IEPS) is calculated applying Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI). The potential impacts of individual pollutants have been modeled for water-based pollutants viz., Chemical Oxygen Demand (COD), Total Phosphorous (TP), and Total Nitrogen (TN) and air pollutants viz., Oxides of Nitrogen (NOx), Oxides of Sulphur (SOx) and Particles Matter (PM10). A kilogram of individual pollutants is taken in modeling to compute the individual impact categories of unit pollutants. The EPS penalty of TN is obtained as highest score of 189.70 i.e. 90.82% shares among six pollutants. The total penalty score for TP, PM10, TN, NOx and SOx, is derived as 13.53 (6.48%), 2.59 (1.24%), 1.30 (0.62%), 1.30 (0.62%) and 0.44 (0.21%), respectively. Hence, it is necessary to integrate effects of pollutants as per the scientific and justified impact caused by individual pollutants derived from the industrial facilities. Therefore, this study recommends for the compliance of EPS penalty of the pollutants based on a result of TRACI. This helps to enforce a scientific and justified polluters’ pay principle.

Abstract:

Arsenic is a ubiquitous heavy metal in various environmental media that include soil, air, and water. Numerous epidemiological studies have reported a close relationship between arsenic and skin carcinogenic effects. In addition, arsenic was also known as a blister agent in skin, and thus its derivatives have been used as a chemical weapon. However, the mechanism of blister formation, one of the most important targets for arsenic toxicity, remains poorly understood. Here we found that arsenic could induce cytotoxicity and inflammation in keratinocyte, which play key roles in the formation of blister. In this study, we used arsenic (AsIII) and trivalent methylated metabolites of arsenic, monomethylarsonous acid (MMAIII), which has been found highly reactive and toxic in various cells. Treatment of AsIII and MMAIII resulted in significant reduction of viability of keratinocyte (HaCaT) in a concentration- and time-dependent manner. Cell death forms, which are apoptosis and necrosis, are occurring simultaneously in AsIII and MMAIII. These cell death were found to be mediated by the reactive oxygen species (ROS), depletion of glutathione by AsIII and MMAIII.  Consistent with these findings, mitochondrial membrane potential disruption, caspase-3 activation and DNA fragmentation were observed by treatments with AsIII and MMAIII, as determined by fluorescence microscopy and flow cytometry. Exposure to arsenicals also stimulated secretion of pro-inflammatory cytokine in keratinocytes, resulting in increased levels of TNF-α, IL-1α, and IL-6.  In summary, this study provides an important evidence for the role of AsIII and MMAIII in arsenic-associated cytotoxicity and inflammation response in keratinocytes, suggesting a new solution to inhibit the toxicant-induced blister formation.

Abstract:

This paper investigates the application of electrocoagulation (EC) and electroflotation (EF) in wastewater originating from mixed vegetable oil (hazelnut oil, sunflower oil, soybean oil, corn oil and canola oil) processing factory. EC has been in use for industrial and domestic wastewater treatment finding more applications using aluminum (Al), iron (Fe) or hybrid Al and Fe electrodes. EF is proved to be perform better than any other methods and effective in removing colloidal particles, oil and grease as well as organic wastewaters.

This study aims to determine the optimum operating conditions for the treatment of wastewaters of mixed vegetable oil plant effluents with high organic pollution load by electrocoagulation method. The effects of pH, conductivity, current density and operating time on the removal efficiency of chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP) and turbidity have been explored. The results show that 87.32 % COD, 51 % TN and 88 % TP removal has been achieved with optimum pH of 7-8 with 3 minutes reaction time and optimum energy of 250 A.

Abstract:

Between 2011 and 2014 (the 12th FYP), China achieved over 7.5% year-on-year growth of per capita GDP; industrial output increased by 10.5%, with equipment manufacturing and high technology manufactures increasing by 13.2 and 11.7 percent, respectively. Most manufacturing activities in the country take place in industrial agglomeration zones. In 2016, there were 613 industrial zones/parks at the national levels and more than 1000 industrial parks in the provincial levels, including the Economic and Technical Development Zones (ETDZs), the Hi-Tech Industries Development Zones, the national Free Trade Zones, the national New Area, and so on. The average growth rate of industrial parks was more than 15%, which had made a greater contribution to our country’s economic development. However, as the concentrated areas of industrial production, industrial parks became the focuses of resource shortage, environmental pollution and ecological destruction. It is necessary to transform the traditional development mode of industrial parks. The general idea of the transformation is to make the industrial park as a large pollution sources, reduce resources consumption, improve optimal manufacturing technology, enhance pollution prevention, control environmental risk, innovate environmental management mechanism, and promoting ecological transformation. The traditional industrial parks could transform to ecological industrial parks with the coordination of economy and environmental protection. In China, there is a national program focused on improving the environmental performance of industrial parks initiated from 1990s, and actively implemented currently: Eco-Industrial Park Demonstration program. As of 2016, 93 zones have been declared as “National Trial EIPs”, and 48 have achieved “National EIP” status. This paper introduced how to evaluate the green development performance of the eco-industrial park according to a evaluation index system. The roles of ecnomic growth, industrial structure, resource utilization, pollution emission and environmental managment as influence factors of eco-efficiency were discussed. The results show that from 2006 to 2015, the intensities of water and comprehensive energy consumption of EIPs reduced 65.9% and 66.1% respectively. The COD emissions intensity and SO2 emissions intensity cut 81.5% and 87.7% respectively. So the EIPs were leading the whole country in resource energy conservation and emission reduction, and achieving transformation and upgrading of industrial parks green development.

Ying-Hen Hsieh is an applied mathematician and a professor at the Department of Public Health, China Medical University in Taiwan. His primary research interests focus on mathematical and statistical modeling of infectious diseases as well as analysis of infectious disease epidemiology relating to public health policies.

Abstract:

Recently, the impact of ambient fine particles, and especially that of particulate matter 2.5 (PM2.5), on human health has garnered much attention. Many studies have revealed positive associations of PM2.5 with human health outcome, including asthma, pulmonary fibrosis, and cancer. Annual PM2.5 concentration in most cities in Taiwan has been higher than the lowest concentration recommended by the World Health Organization (WHO). Long-term exposure to the ambient fine particles potentially causes more severe inflammation and pulmonary epithelium damage in human lung. This study aims to investigate the associations between PM2.5 and human seasonal influenza in cities and counties in Taiwan under the hypothesis that higher exposure concentration is associated with severe lung inflammation and epithelial damage, subsequently humans infected by the influenza virus are likely to have more exacerbating response

Abstract:

The xenobiotic nature and lack of degradability of polymeric materials has resulted in vast levels of environmental pollution and numerous health hazards. Different strategies have been developed and still more research is being in progress to reduce the impact of these polymeric materials. This work aimed to isolate and characterize polyester polyurethane (PU) degrading fungi from the soil of a general city waste disposal site in Islamabad, Pakistan. A novel PU degrading fungus was isolated from soil and identified as Aspergillus tubingensis on the basis of colony morphology, macro- and micro-morphology, molecular and phylogenetic analyses. The PU degrading ability of the fungus was tested in three different ways in the presence of 2% glucose: (a) on SDA agar plate, (b) in liquid MSM, and (c) after burial in soil. Our results indicated that this strain of A. tubingensis was capable of degrading PU. Using scanning electron microscopy (SEM), we were able to visually confirm that the mycelium of A. tubingensis colonized the PU material, causing surface degradation and scarring. The formation or breakage of chemical bonds during the biodegradation process of PU was confirmed using Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy. The biodegradation of PU was higher when plate culture method was employed, followed by the liquid culture method and soil burial technique. Notably, after two months in liquid medium, the PU film was totally degraded into smaller pieces. Based on a comprehensive literature search, it can be stated that this is the first report showing A. tubingensis capable of degrading PU. This work provides insight into the role of A. tubingensis towards solving the dilemma of PU wastes through biodegradation.

Abstract:

Air pollution is a major risk to health in many developed and developing countries of the world. Most of the pulmonary diseases related to air pollution are generally directly or indirectly related to the respirable particulate matter (PM10). Further the health impacts depend on the physical and chemical characteristics of the particulate matter. Mining industries produces huge amount of dust by drilling, blasting, transportation, loading, unloading and mine fires. Now-a-days in India, coal mining is mainly done by opencast methods rather than underground, which generates huge quantities of respirable dust. This paper focuses on the physico-chemical characterisation of particulate matter (PM10 and PM2.5) in and around mechanized opencast coal mines of Talcher coalfields (Mahanadi Coalfield Limited), Odisha, India. The study was carried out for a period of one year from March 2015 to February 2016. The monitoring of particulate concentration reveals that the concentration of both PM10 and PM2.5 levels were far above the standard limit of NAAQS, 2009. The trace metal study by atomic absorption spectrophotometer (AAS) indicated the presence of Fe, Cu, Cr, Zn, Ni, Cd, Pb, As, Se and Hg in the samples. For the qualitative analysis, techniques like Fourier transform infrared (FTIR) spectroscopy, Scanning electron microscopy (SEM) and XRD were used. Source apportionment study of particulate matter was also carried out based on the characterization. Statistical analysis such as correlation analysis and Principle Component Analysis (PCA) was also carried out. Different studies on the particulate matter suggested that monitoring stations near the mining area were mainly affected by the emission from opencast coal mining and its associated activities.

Abstract:


Human activities in coastal areas often utilize waste contaminants that can harm marine life. Kendari municipal waters as coastal areas is an area filled with various activities such as settlements, agriculture, shipping, fishing, and harbor. The biggest impact of these activities are is a heavy metal pollution. Heavy metals will settle in and contaminate marine waters. One marine life livelihoods of coastal communities and the food is shellfish out. The purpose of this study was to determine the presence of heavy metals Zn and Pb and Zn metal pollution levels and Pb contained in shellfish flesh out (Meretrix meretrix) in the Gulf region Kendari, Southeast Sulawesi. Measurement of metal content of shells out performed using Atomic Absorption Spectrophotometer. Analysis of the mussels out show heavy metal content of 2,584 mg Zn / kg and metallic lead (Pb) of 79.71 mg / kg. These results indicate that the levels of heavy metals did not exceed the threshold SNI 01-3548-1994 that is equal to 2 to 100.0 mg / kg of metal Zn and 0.1 to 10 mg / kg for Pb.

Yanping LI ,gradulated from Peking University in 2005,is the director of department of Cleaner Produciton and Pollution Prevention of Chinese Research Academy of Environmental Sciences. The major research areas of Prof.Li are co-control of CP&EPT, eco-industrial assessment, MFA and EMFA,etc.She has aresady published more than 30 articles and 5 books of pollution prevention and control  of environmental pollution.          

Abstract:

Synergy is a new discipline that studies the common features of different things and their synergistic mechanisms which has already been used to transportation control,business management and greenhouse gas emission reduction and air pollutant control etc. With the seriously environmental problems and the more stringent environmental standards, relying solely on the end-of-pipe treatment(EPT) of production system performance is increasingly inadequate. The production system can be devided into two subsystems, namely the Cleaner Prodcution(CP) system  and the End-of-Pipe Treatment(EPT)system determing respectively the pollutant production load(Wpp)and the pollutant emission load(Wept),based on the systematic analysis. So the environmental performance of production system has changed from the single system benefit of EPT into the synergies benefits of CP and EPT. The assessment model of synergy of CP and EPT of production system was established under the hypothesis that the production system pollution discharge meet the requirements of the standard and consume the  minimum energy. It shows that there is synergistic and optimal combination of CP and EPT. This study uses statistical correlation analysis from eight factors of influencing the CP level screening out  three core and quantitative indicators such as purity of raw materials (γ)、raw material yield(ε)and recycling rate(η). While the pollutant removal efficiency(e) is the only factor of EPT.On the basis of material flow analysis(MFA), the difference of environmental performance of industrial production process under different combinations of four indicators was completed by scenario analysis method. Using the above method to complete the case of recycled metal smelting industry.

Speaker

Zhao Ruonan has completed her Master's Degree at the age of 24 years from Renmin University of China and now is studying for a PhD. At her Alma mater. She is working in Chinese Research Academy of Environmental Sciences, and is an engineer of Research Centre for Cleaner Production & Circular Economy, Chinese Research Academy of Environmental Sciences, mainly reponsible for discharge permit system resaerch, environmental economics and environmental management. She has published more than 5 papers in reputed journals.

Abstract:

The discharge permit system has been implemented for more than 20 years in China. Although some rules of discharge permit system can be found in laws and administrative rules and regulations, the discharge permit system has just been carried out as a pilot policy in some provinces. The discharge permit system only serves as a complementary measure of emissions reporting, registration system and total amount control system, while its important position in pollution management policies is still unclear. In fact, it can reduce the transaction cost by defining the property rights, to solve the problems of “free riders” and externalities in the first place. However, the pollution prevention system in China mostly works at a certain stage, with the lack of cohesion and connection. To problems existing in the environmental management, we should take advantage of the discharge permit system, and integrate the current environmental management system. The goal of atmospheric administration is better air quality, better public health, better public welfare, and better production capacity. To achieve this goal, we not only need to control total emissions, but also need to build continuously emission standards. Through the establishment of the atmospheric emission permit system, some of existing loose jumbled, high cost, inefficient management policies can be integrated together, which can benefit the improvement of the air quality, the reduction of the management cost and the increase of the management efficiency. The discharge permit system was first implemented in Sweden, after years of practice, its role in environmental management gains recognition. The discharge permit system in developed countries gradually became the pillar of pollution prevention, and became more institutionalized and normalized. The discharge permit system in China was first implemented in 1987, but our country doesn’t have a law of discharge permit system until now, and we have a certain gap with USA, Germany in emissions trading

Publications cover a wide range of topics,        including ecotoxicological studies  on airborne pollution, microbial characterisation of resuspended dust, description of light absorption properties of laboratory generated tar ball particles, etc.

Abstract:

Atmospheric particulate matter with aerodynamic diameter less than 10 mm (PM10) and 2.5 mm (PM2.5) is now identified as one of the most dangerous pollutants on human health by the EU new directive on air quality (2008/50/CE). Urban airborne pollution has been well characterised from (human) toxicological aspects, also, the role of plants in active/passive biomonitoring has been extensively investigated. On the contrary, little information is available on the ecotoxicity of airborne pollutants. Ecotoxicological tests are controlled, reproducible experiments where ecotoxicity of the sample is most commonly expressed in the form of ECx value, that is, the (calculated) effective concentration which causes x % of ecological effect. In our study the No. 227 OECD GUIDELINE FOR THE TESTING OF CHEMICALS: Terrestrial Plant Test: Vegetative Vigour Test was investigated to find out if it is applicable for assessing the ecotoxicity of water soluble aerosol compounds.  Following the protocol described by the Guideline, Cucumis sativus L. plants were sprayed with the aqueous extract of urban aerosol samples. After the termination of the test, on Day 21, the following end-points were measured: fresh weight, leaf length and visible symptoms. Fresh weight and leaf length did not seem to be negatively affected, the extract even elucidated stimulatory effect at low concentration. On the other hand, the highest concentration applied caused leaf necrosis. This pattern is typically found if the sample contains nutrients which might mask the toxic effect at such low concentrations.

Abstract:

The occurrence of antibiotics in wastewater treatment plant has caused serious problems to the ecosystem and the environment. The emergence of antibiotics-resistant bacteria due to the release of antibiotics-contaminated water from treatment plant has become a worrying issue. This study investigated the removal of antibiotics from wastewater using UV treatments. The main objective of this study was to evaluate the removal of antibiotics from wastewater using two types of UV treatments. Four common antibiotics, namely Ciprofloxacin, Amoxicillin, Cloxacillin and Erythromycin were selected for the degradation using UV photolysis and UV/TiO2 photocatalysis at 254nm UV wavelength, 0.21mW.sec/cm2UV intensity and exposure time of 0, 3, 5, 10 and 15 minutes. The occurrence of antibiotics in influent and effluent at Wastewater Treatment Plant (WWTP) was studied using Quadrupole Time-of-Flight Liquid Chromatography–Mass Spectrometry (Q-TOF LC/MS) and High Performance Liquid Chromatography (HPLC). Q-TOF LC/MS revealed that the presence of antibiotic Erythromycin C (Macrolide) in both influent and effluent. Treatment of antibiotics using UV/TiO2photocatalysis was observed to be more efficient than UV photolysis due to the production of more OH radicals to degrade antibiotics. Removal of Ciprofloxacin, Amoxicillin, Cloxacillin and Erythromycin using UV photolysis at 15 minutes were 20.52%, 14.55%, 13.14% and 8.30%, respectively. Meanwhile, UV/TiO2photocatalysis recorded 43.23%, 37.49%, 35.22% and 27.23% respectively with increase in UV dosage (mJ/cm2). This study provides significant insight on the potential of UV treatments for the removal of antibiotics in wastewater treatment plant.

Abstract:

This paper presents an extensive literature review on water supply and sanitation problems in Nigeria. Although, water resources in Nigeria are enormous, the uneven distribution in time and space creates problems for water availability. Pollution and poor waste management had crippled the revitalization of the country’s economy and environment. Due to this, the economy of Nigeria is developing under increasing water deficiency leading to potential high water loss rates and usage, inadequate accessibility to safe water supply. Unsafe water supply are the major sources of water for the rural populace in Nigeria. Urban areas have low traffic in combination with absent metering and low collection rates for water fees. This also means that operation and maintenance costs for basic services for water supply and sanitation are not covered and cannot be monitored properly by the government. As a result of this problems, water-borne diseases and microbial contaminants, heavy metal accumulations in water exceed maximum permissible limits are the order of the day. Therefore, it is paramount to urgently create awareness and the need to develop water supply systems in Nigeria to standards obtained in the developed world, in line with the implementation for more effective and efficient sanitation systems that can revitalized the environment.

Abstract:

The excessive use of desalination, which is due to the increase in fresh water demand, results in large productions of reject brine. Therefore, the development of an efficient treatment process of the reject brine becomes vital. The Solvay process is one of the main treatment technologies, wherein NH3 is introduced to converting soluble Na+ into insoluble NaHCO3. Although the concentration of Na+ ions are reduced in this process, Cl- ions are not affected. In addition, the concentration of  NH4+  ions increase. Electrocoagulation has been tested for the remove Cl- and NH4+ ions and to regenerate the NH3. When no current was applied, a very small removal of the ions was recorded. Applying a current density of 0.1167 A/cm2 caused an increase in the removal of and Cl-, by 45.9% and 25.87%, respectively at 20°C, 71.55% and 26.88%, respectively at 30°C. This clearly proves that the main removal was due to the electrocoagulation. The effects of current density, initial concentration, and temperature have been studied on the ions removal. It was found that increasing the current density and/or the temperature was found to decrease the residual ions concentration.  Whereas, increasing the initial ions concentration resulted in decreasing the percentage removal.

Abstract:

The aim of this study was to determine the specific water quality characteristics of stormwater constructed wetlands treating stormwater road runoff in a tropical climate. Four representative constructed wetlands were selected as study sites in the peninsular Malaysia. Runoff samples were randomly collected from each site twice every week. The samples were analysed onsite for pH, Dissolved Oxygen (DO) and Temperature. The samples were then transported to a laboratory at the University of Nottingham Malaysia Campus for  further analysis of nitrate-nitrogen and orthophosphate-phosphorus, selected haevy metals such as nickle and copper,biochemical oxygen demand (BOD), solids and microbial contamination by E.coli and intestinal enterococci. The water samples were collected over a period of 12 months from January 2015 until December 2016. Water quality evaluation of the four representative sites through physical, chemical and biological analysis indicated high removal effficiencies compared to published literature. The role of plant (Eleocharis dulcis and Scirpus mucronatus) in removing nitrogen and phosphorus from was also assessed. An analysis of variance revealed that some one the representative sites showed significant diffrences in terms of water quality indicators. The other three sites showed similar water quality charcteristics. This was then associated with the choice of plant species.
