What is environmental risk factors?
Environmental risks to health include pollution, radiation, noise, land use patterns, work environment, and climate change. These risks are driven by policies in sectors outside the health sector, such as energy, industry, agriculture, transport, and land planning.
How does a carcinogen cause cancer?
