Major disciplines of environmental health

 

There are five major disciplines in the field of environmental health. Captain Martin Sanders wishes the public to understand the role of Public Health Officers, as he lays down an overview of each discipline that has an impact on our natural and built environments.

Environmental epidemiology

It studies the impact of environmental exposures on human health, such as exposure to radiation, chemicals, microbiological agents, etc. However, with ethical considerations, these studies are 'observational' in nature, meaning information is gathered after exposure has occurred.

Toxicology

Unlike environmental epidemiology, studies here involve animal subjects to determine the effects of environmental exposure and to understand possible health outcomes in humans. Careful analysis and interpretation must be considered since animal- and human biology are significantly different.

Exposure science

Studies under this discipline support environmental epidemiology by identifying and quantifying exposures. It describes the exposure and its impact on health, identifies them through toxicology study, or determines exposure levels. These are like lab results that a doctor uses to assess a person's health based on the numbers that he or she sees.

Environmental engineering

The main goal of this discipline is to protect human health, the health of organisms, and the quality of the environment. To achieve this, environmental engineers devise solutions such as wastewater management, recycling, air and water pollution control, among others.

Environmental law

This is simply concerned with statutes, regulations, treaties, common laws, and customary laws which govern and addresses human activity and its impact on the environment.
