Environmental Health Risk Assessment

Issue identification

Identify concerns that the risk assessment needs to address

Hazard identification

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

Dose-response assessment

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?

Exposure assessment

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

Discuss uncertainties/unknowns

Risk characterization

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.
