Document Summary
Exposure: contact between a chemical and a person or organ. Endogenous: internal exposure: hormones, reactive oxygen, species, lipid peroxidation. Biomarkers of effect= quantifiable bio response due to toxicant : measure the response. Effect: a quantifiable biological response due to toxicant exposure. Adduct: a relatively stable covalent bond between a toxicant and biological receptor. Quantitative estimation of exposure received by population over a period of time. Classification of exposure status relative to other members of a population. Write out an explain how hazards lead to adverse health effects. Give a definition and explanation of each method and tool. Levels of chemicals/their products in biological samples. Give some examples of endogenous and exogenous exposures. Don"t memorize the equation, but make sure you understand it. Residence time of a toxicant in the body determine its utility as a exposure biomarker. List some organizations, agencies, and safeguards that have been put in place to prevent widespread, dangerous exposures, and danger in the workplace.
