Variation of hydrochemical conditions, with special reference to adequacy of waters as fish habitats, was traced based on selected hydrochemical parameters obtained during the studies conducted from February 2013 till February 2014 year. The results were compared with earlier studies. The sources of organic pollution were identified, and the effect of biogenic substances on the biomass, as well...

cleanup. Major compounds that have been shown to increase the solubility and thus the mobility of nutrients Mobile organic sorbents (MOS) such as dissolved and colloidal and contaminants are surfactants (Edwards et al., 1991; phase organic matter control flow of water and transport of solutes in soils. We studied the effect of MOS on contaminant fate by systematic Haulbrook et al., 1993; Rahman...

Formation of non bonded organic layer around inorganic particles like iron sulfide and zeolites, was hypothesized as starting point for one of the possible mechanisms of the origin of life on earth. In this study, the general circumstances needed for creation of such organic layer was investigated. An aliphatic hydrocarbon (hexane), an aromatic hydrocarbon (toluene), an alcohol (n-octanol) and ...

Reactions involving iron play a major role in the environmental cycling of a wide range of important organic, inorganic and radioactive contaminants. Consequently, a range of environmental clean-up technologies have been proposed or developed which utilise iron chemistry to remediate contaminated land and surface and subsurface waters, e.g. the use of injected zero zero-valent iron nanoparticle...

Constructed wetlands are in use to improve the quality of contaminated groundwaters at many sites in the USA. Target contaminants include both organic and inorganic constituents. Volatile and nonvolatile hydrocarbons are found in ground water at closed petroleum refinery sites, and in leachates from landfills. Polycyclic aromatic hydrocarbons are pollutants at many sites. Chlorinated organics o...

Phytoremediation is a technology that is based on the combined action of plants and their associated microbial communities to degrade, remove, transform, or immobilize toxic compounds located in soils, sediments, and more recently in polluted ground water and wastewater in treatment wetlands. Phytoremediation could be used to treat different types of contaminants including petroleum hydrocarbon...
