Environmental Health Risk Assessment
Identify concerns that the risk assessment needs to address
What adverse effects are likely to occur from an exposure to a chemical or other substance?
Are adverse health effects likely to occur in humans?
Examine the available scientific data for the given chemical, group of chemicals, or other substances
Characterize the link between the negative effects and the chemical/other agent
Describe how the likelihood and severity of adverse health effects (the responses) are related to the amount and type of exposure to the substance
What type of health problems may be caused by the exposure?
What is the chance of people experiencing these health problems when exposed to different levels?
Are there any exposure levels that do not pose a health risk?
Estimate the magnitude, frequency, and duration of exposure to the chemical or other substance in the environment
Exposures are commonly estimated indirectly through measured concentrations in the environment, models of exposure, and estimates of human intake over time
If chemical has not yet been released, estimate future exposures
Are some people more likely to be exposed to certain chemicals or substances due to the nature of their work, the food they consume or other reasons?
Discuss the size, nature, and types of human populations exposed to the substance
Please input your judgment on the following:
the nature and presence or absence of risks;
information about how the risks were assessed;
where assumptions and uncertainties still exist;
and where policy choices will need to be made.
