Environmental risks to health include pollution, radiation, noise, land use patterns, or climate change .
What is environmental transition model?
Environmental risk transition is the process by which traditional communities with associated environmental health issues become more economically developed and experience new health issues . ... As economic development occurs, these environmental issues are reduced or solved, and others begin to arise.
Who made the epidemiological transition model?
The term ‘epidemiologic transition’ was coined by epidemiologist Abdel Omran in an influential 1971 paper that described how “degenerative and man-made diseases displace pandemics of infection as the primary causes of morbidity and mortality” in many high-income countries.

What is Stage 3 of the demographic transition?
Stage 3: Total population is rising rapidly . The gap between birth and death rates will narrow. Natural increase is high. Death rates will now remain low and steady (to 15 per 1,000) but birth rates will fall quickly (down to around 18 per 1,000).
What is Stage 2 of the demographic transition model?
Stage 2 of the Demographic Transition Model (DTM) is characterized by a rapid decrease in a country’s death rate while the birth rate remains high . As such, the total population of a country in Stage 2 will rise because births outnumber deaths, not because the birth rate is rising.

Olshansky and Ault [10] proposed a “fourth stage” of epidemiologic transition, “ The Age of Delayed Degenerative Diseases ,” in which declining age-specific mortality results in a gradual shift of non-communicable burden to older ages, with underlying causes of death showing little change overall.

What are environmental risks?
Environmental risk is the probability and consequence of an unwanted accident . Because of deficiencies in waste management, waste transport, and waste treatment and disposal, several pollutants are released into the environment, which cause serious threats to human health along their way.

- Pollution. ...
- Climate Change.
How do you assess environmental risk?
- identify any hazards, ie possible sources of harm.
- describe the harm they might cause.
- evaluate the risk of occurance and identify precautions.
- record the results of the assessment and implement precautions.
- review the assessment at regular intervals.
