Degrees Similar to Environmental Health

Biomedical Sciences
The biomedical sciences discipline combines the fields of biology and medicine to focus on the health of both humans and animals. Biomedical scientists develop new treatments and therapies for illnesses, diseases, and disabilities. They research medical conditions such as cancer, diabetes, anemia, stress, and aging. Students pursuing a biomedical sciences degree begin their studies with an emphasis on courses in biology, general chemistry, and organic chemistry. In advanced courses they explore the application of knowledge in these areas to conducting biomedical research and ultimately finding scientific solutions to health problems around the world.

Environmental Planning
Degree programs in environmental planning teach students how to balance human needs and wants with environmental sustainability and protection. Classes span the principles of general architecture, landscape architecture, interior architecture and design, and urban and rural development. The curriculum may also include coursework in sociological concepts in environmental planning. Topics addressed in this area may include poverty and the environment, population and environmental planning, and social policies that shape environmental planning.

Environmental Studies
Students of environmental studies are exposed to the natural sciences, the social sciences, and the humanities. They apply knowledge from each of these areas to examine how resources can be sustained in the face of increasing populations, various forms of pollution, and the endangerment of species and natural systems.

Epidemiology
Epidemiology, a fundamental science of public health, is concerned with health and disease at the population level; that is to say, within groups or communities. Its focus is the frequency, pattern, causes, and risk factors of diseases and other health-related events within these specified populations, which range from neighborhoods and schools to cities, states, countries, and the world at large. Epidemiologists – often referred to as disease detectives – are the scientists and investigators whose work begins with looking for clues by asking questions. Who is sick? What are their symptoms? When did they get sick? Where could they have been exposed? Using statistical analysis, epidemiologists study answers to these questions and produce data that lead them to identify how a particular health problem was introduced, how its spread can be controlled, and how it can be prevented.

Materials Science
Materials scientists apply principles of engineering, physics, and chemistry to study existing materials and invent and manufacture new materials. Their work has broad applications to solving real-world problems. It is essential to our everyday lives. Degree programs in materials science cover the structure and composition of materials, how they behave under various conditions, and how they can be manipulated and combined for specific uses in specific industries – from health and engineering to electronics, construction, and manufacturing.

Occupational Health
Occupational health (OH) is all about protecting people at work. OH degree programs teach students how to recognize workplace hazards, conduct a workplace safety audit, develop and deliver workplace safety programs, understand factors that impact worker health and performance, develop emergency procedures and fire control systems, deal with hazardous spills, and manage workers’ compensation claims.

Public Health
Students who enter degree programs in public health look at how access and lack of access to healthcare, health education, and funding affect the spread, treatment, and prevention of disease. Epidemiology – the science concerned with the spread and control of diseases and viruses – is the science at the heart of public health.

Toxicology
We are all exposed to chemicals. Many of them benefit society. Some, however, may threaten our health. Pesticides in the food we eat, pollutants in the air we breathe, chemicals in the water we drink, adverse effects of drugs used to treat disease – these are the subjects of toxicology. These are the concerns of toxicologists, who seek to understand the effects of exposure to harmful substances, to improve the health and safety of humans and other living organisms, and to protect the environment in which we live. Toxicology connects knowledge from biology, chemistry, medicine, veterinary medicine, pharmacology, public health, and environmental science.
