Abstract: The volatilization of organic environmental contaminants from water bodies to the atmosphere was investigated. The general aim was to elucidate the factors that control the volatilization process and develop predictive methods for calculating volatilization rates for various compounds from rivers, lakes and other water bodies under various conditions of.

Organized into 47 chapters, this book first describes the aquatic pollutants and their potential biological effects. Subsequent chapters elucidate chemicals with pollution potential; multidetection approach to analysis of organic pollutants in water; volatilization of pollutants from water; microbial transformations of aromatic pollutants; and photochemical transformation of pollutants in water.

Other POPs such as volatilized industrial pollutants as well as pollutants from fuel combustion can also contaminate large areas due Cited by: Product Type: Book Edition: 1 First Published: eBook: Abstract. Coefficients for the volatilization from water of 1,1,1-trichloroethane and 1,2-dichloroethane were measured in a stirred tank.

Experiments at constant mixing conditions over a wide range of concentrations showed that the volatilization coefficient was independent of concentration, confirming the assumption that volatilization is a first order by: 7.

As a cause of oxygen depletion, organic pollutants released into water streams from industrial discharges, fertilizers, pesticides, detergents or consumed medicines can.

Soils are a major reservoir of organic pollutants, and soil–air partitioning and exchange are key processes controlling the regional fate of pollutants. Here, we report and discuss the soil concentrations of polycyclic aromatic hydrocarbons (PAHs), their soil fugacities, the soil–air partition coefficients (KSA) and soil–air gradients for rural and semirural soils, in background Cited by: Identification & analysis of organic pollutants in water Hardcover – January 1, by Lawrence H.

The volatilization rate of soil‐incorporated chemicals is controlled by vapor pressure of the chemical in soil and by its rate of movement to the soil surface by diffusion or by a combination of diffusion and convection in evaporating water.

Vapor pressures of organic chemicals are greatly decreased by their interaction with soil mainly due Cited by: Persistent organic pollutants (POPs) are toxic chemicals that adversely affect human health and the environment around the world.

Because they can be transported by wind and water, most POPs generated in one country can and do affect people and wildlife far from where they are used and released.

They persist for long periods of time in the. The soil is the medium through which pollutants originating from human activities, both in agriculture and industry, move from the land surfaces to groundwater.

Polluting substances are subject to complex physical, chemical and biological transformations during their movement through the soil.

Their displacement depends on the transport properties of the water-air-soil Reviews: 1. The book focuses on the following topics: Biological Wastewater Treatment Technologies.

Modeling long-term uptake and re-volatilization of semi-volatile organic compounds (SVOCs) across the soil–atmosphere by: Removal of organic pollutants from municipal wastewater can also take place by means of volatilization, i.e., transformation from the form dissolved in water to gaseous.

Currently, reservoir water pollution problems are becoming increasingly prominent, especially organic pollution, and the levels of nitrogen and phosphorus exceed the standards for drinking water quality (Ministry of Health PRC ).The eutrophication degree of water sources is increasing annually, but the conventional water plant processes have limited removal abilities for organic Cited by: 1.

While organic pollution occurs naturally, inorganic pollution is a result of some human interaction or doing (such as fluoride in the water supply which is used to help teeth health).

Groundwater is very vital to the environment as most old wells use it, and plants use groundwater along with rainfall to grow(1). Organic pollutants consist of proteins, carbohydrates, fats and nucleic acids in a multiplicity of combinations. Raw sewage is 99,9 per cent water, and of the 0,1 per cent solids, 70 per cent is organic (65 per cent proteins, 25 per cent carbohydrates, 10 per cent fats).

Australians are the second highest producers of waste in the world. Australians generate approximately million tonnes of waste, which averages out to 2, kilograms of waster per person each year. Australia depends on landfill for waste management. It was found in that million tonnes.
