HISTORY AND DEVELOPMENT OF ENVIRONMENTAL
HEALTH SCIENCE
1. Environmental health science is an interdisciplinary field that combines
elements of environmental science, biology, epidemiology, and public health
to study the impact of environmental factors on human health. The history and
development of environmental health science can be traced back to the late
19th century, when scientists first began to recognize the relationship between
environmental factors and disease.
2. One of the earliest pioneers in the field was John Snow, who in 1854 traced the
source of a cholera outbreak in London to contaminated water from a single
well. This discovery paved the way for the development of modern
epidemiology, the study of the patterns, causes, and effects of diseases in
populations.
3. During the 20th century, environmental health science grew rapidly as a result
of a number of public health crises, including outbreaks of typhoid fever and
polio, as well as environmental disasters such as the Love Canal toxic waste
site in New York and the Bhopal chemical disaster in India.
4. In response to these crises, governments and international organizations began
to invest in research and policies to address environmental health concerns. In
1948, the World Health Organization (WHO) established a Division of
Environmental Health to coordinate international efforts to monitor and control
environmental health hazards. In the United States, the Environmental
