BIOGEOCHEMICAL STANDARDS

Abstract

From the biogeochemical point of view, the environmental pollution is a process of reversible and/or irreversible disturbance of biogeochemical structure of both terrestrial and aquatic ecosystems. To prevent this disturbance, the anthropogenic loads of pollutants must be decreased significantly. There are different approaches in environmental chemistry and ecotoxicology aiming to set various criteria, threshold levels, and standards to control the pollution of various biosphere compartments and decrease the rate of human and animal diseases. These methods are generally based on experimental modeling with various animals and there are many uncertainties in the implication of the results for real environmental conditions.
