Description:
Assessing the risk of toxic chemicals to soil nutrient cycling processes involves an understanding of the potential for chemical effects on the diversity and the activity of the microbial communities and higher life forms in the natural system. ssessments of risk associated with the effects of toxic chemicals to nutrient cycling processes in soil must include the potential for effects to the Physical and biochemical life support processes, effects to the diversity of microbial communities and higher life forms in the system, and the temporal and spacial scales of change involved with the effects process. ubstantial progress has been made in discerning how anthropogenic stressors affect the cycling of nutrients in soil. ost of the work has focussed on individual assessments at specific sites using endpoints designed to measure ecosystem structure or process effects. his chapter summarizes much of the literature and seeks to integrate or suggest needed research activities to assure further progress in understanding the ecotoxicology of nutrient cycling.
