New hazard index tool to aid risk assessment of exposure to multiple chemicals

Evaluating the level of danger to human health from exposure to multiple chemicals in contaminated sites is a complex task.

To address this difficulty, researchers have developed a new screening tool that can be incorporated into public health risk assessment, which may include polluted former industrial plants, waste dumps, or even land where pesticides have been used.

This ‘hazard index’ approach indicates when risk to health is high, which organs are most affected, and where further evaluation should be conducted in the context of environmental or occupational exposure at such sites.
