Metals in the environment: design of HRA Heavy Metals, an online system for assessing human health risks

摘要

HRA Heavy Metals is a program designed for Health Risk Assessment (HRA) by determining human exposure to environmental metals for a specific subject. This online program is used to establish if the presence of metals in the area where the individual inhabits exceeds the safety limits established by the current legislation. The use of HRA Heavy Metals requires information on metal concentrations in tap water, superficial soils and air, corresponding to each particular subject. This paper describes in detail the basis of the program and its operation.
