- What is environmental epidemiology?
- The study of how environmental exposures affect the frequency and distribution of disease in populations
- What is an exposure assessment in environmental epidemiology?
- The process of measuring or estimating the type, amount, and duration of an environmental exposure a population experiences
- What is a biomarker of exposure?
- A measurable biological indicator, such as blood lead level, that reflects an individual's exposure to a substance
- What is the exposome?
- The totality of environmental exposures an individual experiences over their lifetime
- What is a dose-response relationship in toxicology and environmental epidemiology?
- The relationship between the amount of exposure to a substance and the magnitude of the health effect
- What is the difference between acute and chronic exposure?
- Acute exposure is a single or short-term exposure, while chronic exposure occurs repeatedly or continuously over a long period
- What is bioaccumulation?
- The gradual buildup of a substance in an organism over time, often because it is absorbed faster than it is eliminated
- What is biomagnification?
- The increasing concentration of a substance at each higher level of a food chain
- What health effects are classically associated with chronic lead exposure in children?
- Neurodevelopmental delays and cognitive impairment
- What was the primary historic source of lead exposure that was reduced by regulation in the United States?
- Leaded gasoline and lead-based paint
- What respiratory conditions are associated with chronic exposure to fine particulate matter (PM2.5) air pollution?
- Asthma exacerbation and chronic obstructive pulmonary disease
- What is the Air Quality Index (AQI) used for?
- Communicating the level of air pollution and associated health risk to the public
- What waterborne disease outbreak famously helped establish the field of epidemiology through John Snow's investigation?
- The 1854 London cholera outbreak
- What environmental epidemiology method did John Snow famously use in his cholera investigation?
- Spot mapping of cases to identify the contaminated Broad Street pump
- What is an ecological study design commonly used for in environmental epidemiology?
- Comparing exposure and outcome rates across groups or geographic areas rather than individuals
