What is epidemiology toxicology?

Epidemiology is the study of disease in human populations, while toxicology is the study of how poisonous substances affect organisms’ health. Scientists also want to understand how these hazards affect people.

What is the epidemiology of air pollution?

Air pollution epidemiology is an invaluable tool in providing evidence for establishing causal associations between air pollution and a number of health outcomes, and in quantifying risk related to exposure to air pollution.

What is the meaning of air toxicity?

Hazardous air pollutants, also known as toxic air pollutants or air toxics, are those pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects.

What are the 3 major contaminants in the air?

Ozone (O3) Nitrogen dioxide (NO2) Carbon monoxide (CO)

How is toxicology and epidemiology related?

Epidemiology thus appears as a source of knowledge that is particularly complementary to toxicology in objectivizing the effects of pesticides on the health of exposed populations. Indeed, epidemiologists apply statistical methods to population health in order to understand the factors.

What is the difference between toxicology and epidemiology?

One obvious difference between the two types of exposure assessment is that toxicological studies draw on relatively precise dosing information and create dose-response curves, whereas epidemiologic studies must rely on other sources of exposure information such as self-reports, environmental monitoring, or body burden …

What are the 4 types of air pollution?

Types of air pollution

  • particulate matter.
  • nitrogen dioxide.

What are the 7 major air pollutants?

Major air pollutants include carbon monoxide (CO), ammonia (NH3), nitric oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), sulphur dioxide (SO2) and volatile organic compounds (VOC).

What are the 6 major air pollutants?
