What is the Risk of Cancer from Exposure to Particulate Matter?


Cancer Mortality Risks from Long-term Exposure to Ambient Fine Particle (Abstract, Chit Ming Wong, Hilda Tsang, Hak Kan Lai, G. Neil Thomas, Kin Bong Lam, King Pan Chan, Qishi Zheng, Jon G. Ayres, Siu Yin Lee, Tai Hing Lam, and Thuan Quoc Thach. Cancer Epidemiol Biomarkers Prev, Feb. 22, 2016)

Today we review research that looks at the impact of fine particulates on health, specifically on the risk of cancer, based on 10 years of exposure to this pollution for a large sample of older people (older than 65), living in an urban environment (Hong Kong). Results indicate for every 10 µg/m³ increase in exposure, the risk of dying by cancer goes up by 35% for men (mainly in the digestive tract) and for women the risk of mortality because of breast cancer goes up by 80%. The authors caution that more research is needed to look at the link between cancer other air pollutants in combination with particulate matter.
