Investigation of the relationship between Hg speciation in soil and human health and ecological risk assessment

Mercury (Hg) pollution in soils can have major effects on human health and ecological systems. Concentrations, toxicological behaviour and bioavailability of different Hg species, both in the environment and in biological systems differ greatly, and are significa nt in the estimation of both human health and ecological risk assessment. Herein the significance of appropriate selection of species in both human health and ecological risk assessments is considered.
