  • - Chemical Exposures: Involves assessing the health effects of exposure to hazardous chemicals, pollutants, and toxins in the environment, workplace, or home.
  • - Physical Exposures: Examines the health consequences of exposure to physical factors such as radiation, noise, temperature extremes, and electromagnetic fields.
  • - Biological Exposures: Deals with infectious agents, allergens, and other biological hazards that can affect individuals in their environment.
  • - Occupational Exposures: Focuses on health issues related to workplace exposures, including hazardous substances and occupational diseases.
  • - Environmental Epidemiology: Studies patterns of disease in populations and their relationship to environmental exposures.
