Millions of Canadian workers face exposure to known and suspected occupational carcinogens. This study quantifies risks from agents like night shift work and diesel exhaust, highlighting workplace cancer concerns.
Area of Science:
- Occupational health and safety
- Environmental epidemiology
- Risk assessment
Background:
- Occupational carcinogens pose significant risks to worker health.
- Previous CARcinogen EXposure (CAREX) projects in the European Union (EU) provided a framework for assessing exposure.
- Estimating the burden of occupational carcinogen exposure in Canada is crucial for public health interventions.
Purpose of the Study:
- To estimate the number of Canadian workers exposed to known and suspected occupational carcinogens.
- To adapt and apply the CARcinogen EXposure (CAREX) methodology to the Canadian context.
- To identify priority carcinogens and estimate exposure levels in Canadian workplaces.
Main Methods:
- Developed the CAREX Canada project, estimating prevalence and levels of exposure to occupational carcinogens.
- Utilized the International Agency for Research on Cancer (IARC) classifications for known, probable, and possible human carcinogens.
- Established a Canadian Workplace Exposure Database and integrated CAREX EU data, using expert assessment and 2006 Census of Population data for prevalence estimates.
Main Results:
- Estimated exposure numbers for 44 known, probable, and suspected carcinogens.
- Developed detailed exposure level estimates for 18 priority agents.
- Identified high prevalence exposures: night shift work (1.9 million), solar ultraviolet radiation (1.5 million), and diesel engine exhaust (781,000).
Conclusions:
- A significant proportion of the Canadian workforce is exposed to workplace carcinogens.
- The findings underscore the need for targeted interventions to reduce occupational cancer risks.
- CAREX Canada provides essential data for occupational health policy and prevention strategies.
