groundwater is the main source of potable water in most areas of mazandaran province, like sari and babol city. thus the safety of groundwater supplies is very important in these regions. unfortunately attention to groundwater quality has remained limited in iran. in recent years, the growth of industry, technology, population, and water use has increased the stress upon both land and water res...

A coupling kinetics model is developed to simulate the release and transport of landfill leachate pollutants in a deformable municipal solid waste landfill by taking into account of landfill settlement, seepage of leachate water, hydrolyse of insoluble and degradable organic pollutants in solid phase, biodegradation of soluble and degradable organic pollutants in solid phase and aqueous one, gr...

The University of Minnesota is committed to the policy that all persons shall have equal Acknowledgements The Minnesota Pollution Control Agency (MPCA) provided funding for this review. The involvement of the project manager from the MPCA, Bruce Wilson, was greatly appreciated. Executive Summary Recently, there has been an increased interest in the use of infiltration as a method of managing st...

The volume of e-waste is growing around the world, and, increasingly, it is being disposed of by export from developed to developing countries. This is the situation in Ghana, and, in this paper we address the potential consequences of such e-waste disposal. Herein, we describe how e-waste is processed in Ghana, and what the fate is of e-waste-chemical contaminants during recycling and storage....

Persistent organic pollutants in drinking water impose a substantial risk to the health of human beings, but the evidence for liver toxic effect and the underlying mechanism is scarce. This study aimed to examine the liver toxicity and elucidate the molecular mechanism of organic pollutants in drinking water in normal human liver cell line L02 cells and rats. The data showed that organic extrac...

Wastewater treatment is gaining importance because of increasing awareness about health effects of water pollutants and stringent norms of regulatory bodies. Removal of heavy metals from industrial effluent can be carried out by various methods like ion exchange, adsorption, activated sludge process, electro coagulation, membrane separation processes, precipitation, coagulation etc. Arsenic is ...

One of the main results of the processes related to urbanization is the contamination of the adjacent water bodies. Inserted in this context, the Rodrigo de Freitas lagoon is situated in the south zone of the city of Rio de Janeiro. This ecosystem receives several inputs containing all sorts of pollutants, including heavy metals. The present work aimed to study the partitioning of heavy metals ...

Phenol is one of the most common water pollutants found in industrial effluents. The phenol removal potential of a chemically modified macrofungus Trametes sp., was investigated in a batch system. The effects of particle size, pH, temperature, contact time and biosorbent dosage have been investigated. The optimum conditions for phenol removal were found to be particle size: 150-300 μm, pH: 6.0 ...

Polypropylene nonwovens were functionalised using a self-assembled, amphiphilic cyclodextrin coating and the potential for water purification by removal of pollutants was studied. As benzene is one of the problematic compounds in the Water Framework Directive, six volatile organic compounds (benzene and five benzene-based substances) were chosen as model compounds. The compounds were tested as ...

The increasing worldwide contamination of freshwater systems with thousands of industrial and natural chemical compounds is one of the key environmental problems facing humanity. Although most of these compounds are present at low concentrations, many of them raise considerable toxicological concerns, particularly when present as components of complex mixtures. Here we review three scientific c...
