Environmental considerations pollutants, organic

But if we take into account the emerging pollutants and compounds, the choice of which is guided by environmental considerations (mainly risks for health), then surfactants, endocrine disruptors, pesticides, other industrial organics (PAH, aromatic amines,...) or inorganics (sulphides, arsenic,...) and microbiological indicators (pathogens) must also be considered. 

Keeping the same format as the first edition, the text begins with coverage of the basic principles underpinning the environmental behavior and effects of organic pollutants. It then describes the properties and ecotoxicology of major pollutants and explores future prospects. In the last section, the author discusses some issues that arise after consideration of the material in the second part of the text. 

The text is divided into three parts. The first deals with the basic principles underlying the environmental behavior and effects of organic pollutants the second describes the properties and ecotoxicology of major pollutants in reasonable detail the last discusses some issues that arise after consideration of the material in the second part of the text, and looks at future prospects. The groups of compounds represented in the second part of the book are all regarded as pollutants rather than simply contaminants, because they have the potential to cause adverse biological effects at realistic environmental levels. In most cases these effects have been well documented under environmental conditions. The term adverse effects includes harmful effects upon individual organisms, as well as effects at the level of population and above. 

All these contaminants enter into the environment through human activities (urban waste, deposits of the waste cleaning plants and agricultural cultivations) [45] and various other pathways (atmospheric and fluvial transport) [46]. Environmental pollution by these groups of organic compounds has received considerable attention as a result of public awareness towards environmental problems and expectations for good quality of life [13]. 

Thus the consideration of kinetics of POP sorption by particulate soil organic matter appreciably changes the pollutant vertical distribution, particularly during the clearance period, which increases this period substantially. Accordingly, this is of great importance to environmental risk assessment of POPs exposure to living organisms.
