The amount of a substance that is absorbed or becomes available at the site of physiological activity.
Bioavailability
Process of using medical tests such as blood or urine collection to determine whether a person has been exposed to a contaminant and how much exposure he/she has received.
Biomonitoring
Field of public health science that focuses on the incidence and prevalence of disease or illness in a population from exposure in their environments.
Environmental epidemiology
A field of public health science that focuses on how the environment influences human health.
Environmental health
The belief that no group of people should bear a disproportionate share of negative environmental health consequences (regardless of race, culture, or income).
Environmental justice
The total amount of a contaminant that comes in direct contact with the body.
Exposure
Factors that determine a person’s level of exposure to a contaminant.
Exposure estimate
Method by which people are exposed to an environmental contaminant that originates from a specific source.
Exposure pathway
Process to help determine whether an individual has been exposed to environmental contaminants.
Exposure history
If something has the potential to cause harm to humans or the environment, then precautionary measures should be taken even if there is a lack of scientific evidence for cause and effect.
Precautionary principle
Communities that optimize the physical, social, and economic environments of the community.
Healthy communities
Process to determine the likelihood or probability that adverse effects such as illness or disease will occur in a group of ppl because of an exposure to an environmental contaminant.
Risk assessment
The study of the adverse effects of chemical, physical, or biological agents on people, animals, and the environment.
Toxicology
Consisting of many diffuse sources
