Exposure assessment is an evaluation of the potential exposures to humans and the environment from the production, distribution, use, disposal and recycle of a chemical substance. Exposure happens through contact with a chemical. Such contact will occur by breathing air, potable, intake food, or touching a range of product that contain the chemical. The concentration of the chemical and therefore the extent of the contact square measure necessary parts of exposure assessment. The results of AN exposure assessment square measure usually thought of with a hazard assessment of the chemical. A hazard assessment provides AN understanding of the potential for the chemical to cause adverse effects to humans and plant and animal life. Together, the exposure assessment and therefore the hazard assessment may be combined into a risk assessment, which reaches conclusions concerning the chance of adverse effects within the exposed population. Exposure assessments include occupational exposures in the workplace generally workers activity exposures within the work, exposures to the final population from chemicals within the air and potable, client exposure through the home use of product, and environmental exposure to aquatic life. Representative measured exposure information obtained beneath realistic conditions square measure usually a lot of correct than shapely estimates. However, models will give helpful exposure estimates. OPPT's models and tools square measure meant to be employed by scientists and engineers acquainted with exposure assessment principles.
