An integral part of urban development is increasing environmental pollution and relevant ecological risks for human and ecosystem health due to disturbance of biogeochemical food webs (Bashkin, 2002).

There are different approaches in environmental chemistry and ecotoxicology aiming to set various criteria, threshold levels, and standards to control t

In the previous chapters we have considered the natural biogeochemical cycles of various chemical elements and their alterations under anthropogenic activity. We can conclude that at present the alteration of biogeochemical cycling under the influence of humans is undoubtedl
