Non-anthropogenic chemicals

Polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and ortho-unsubstituted polychlorinated biphenyls (non-ortho polychlorobiphenyls) are three structurally and toxicologically related families of anthropogenic chemical compounds that have in recent years been shown to have the potential to cause serious environmental contamination due to their extreme toxicity [77-82], These substances are trace-level components or byproducts in several large-volume and widely used synthetic chemicals, principally polychlorobiphenyls and... 

Tab. 2 Summary of selected anthropogenic contaminants identified in the extracts of the Teltow Canal sediments as published previously (Schwarzbauer et al. 2001 Ricking et al. 2003). Compounds not identified in the non-extractable residue after application of chemical or pyrolytic degradation procedures are given in italics.

Apart from natural emissions, Cd is usually found in the environment because of several anthropogenic activities. Due to its chemical and physical properties, Cd is widely used in special alloys (e.g., copper-, tin-, lead-, or zinc-based alloys), pigments (as Cd sulfide and sufoselenide), stabilizers (e.g., Cd incorporated into poly(vinyl chloride)), NiCd batteries and coatings (e.g., steel, aluminum and other non-ferrous metals). Of course, the manufacturing.
