Tools for risk assessment of acute and chronic effects due to metal and metalloid exposition

Abstract

The global situation of environmental exposure, sometimes metallic, remains latent at present and increases when it comes to natural disasters, mayor use and difficulties in waste management, so that the tools to establish the risk by exposure to chemicals, as the key element for decision making and interventions in various situations such as contaminated sites where health or environmental damage is suspected, for when the final destination is a waste, when associated with natural disasters, for scientific purposes associated with sustainable technology, or to resolve legal conflicts, within the most frequent ones. The proposed tools allow to assess the risk or safety of the objective form for acute and chronic exposures, which facilitates decision making as corrective or mitigation actions in order to reduce the impact on health and the environment.
