Occupational cancer risks in Quebec were estimated, revealing significant worker exposure to solar radiation, shift work, and diesel exhaust. This highlights key areas for intervention to reduce cancer incidence.
Area of Science:
- Occupational health
- Environmental epidemiology
- Cancer research
Background:
- Raising awareness of occupational cancers in Quebec, Canada.
- Estimating the prevalence of occupational carcinogen exposure.
Purpose of the Study:
- To quantify worker exposure to recognized and probable carcinogens in Quebec.
- To inform public health initiatives and research priorities for occupational cancer prevention.
Main Methods:
- Utilized data from workplace monitoring, research projects, surveys, and radiation protection records.
- Incorporated estimates from the Carcinogen Exposure Canada (CAREX Canada) Project database.
- Applied carcinogen exposure proportions to Quebec labor force data.
Main Results:
- Solar radiation was the most prevalent exposure (6.6%), followed by night/rotating shift work (6.0%), diesel exhaust (4.4%), wood dust (2.9%), and polycyclic aromatic hydrocarbons (2.0%).
- Over 15 carcinogens were detected across various industrial sectors.
- Up to 100,000 young workers are employed in sectors with multiple carcinogen exposures.
Conclusions:
- Crude estimates identify key research and intervention priorities for occupational cancer in Quebec.
- The findings underscore the need for targeted strategies to mitigate exposure to prevalent carcinogens.
