risk =
hazard plus exposure
exposure pathway
source of contamination
environmental media and transport mechanism
point ofexposure
route of exposure
receptor population
environmental media and transport mechanism
where contamination is housed
point of exposure
where people come in contact with the contained medium
route of exposure
how the contaminant enters the body
receptor population
population of people who are likely to be exposed
any safe level of lead
no
bioavaiblity
amount of contaminant that actually ends up in the systemic circulationt
toxicology
study of the adverse effects of chemical, physical, or biologic agents on people, animals and the enviornment
exposure estimate
determines a persons level of exposure to a contaminant
biomonitoring
process of using medical tests such as blood or urine collection to determine if a person has been exposed to a contaminant and how much exposure he or she has received
