The aim of this study was to introduce the Canadian job-exposure matrix (CANJEM).
Four large case-control studies of cancer were conducted in Montreal, focused on assessing occupational exposures by means of detailed interviews followed by expert assessment of possible occupational exposures. Thirty-one thousand six hundred seventy-three jobs were assessed using a checklist of 258 agents (listed with prevalences at http://expostats.ca/chems). This large exposure database was configured as a JEM.
CANJEM is available in four occupational classification systems. It provides estimates of probability of exposure among workers with a given occupation, and for those exposed, various metrics of exposure. CANJEM can be accessed online (www.canjem.ca) or in a batch version.
CANJEM is a large source of retrospective exposure information, covering most occupations and many agents. CANJEM can be used to support exposure assessment efforts in epidemiology and occupational health.
本研究旨在介绍加拿大工作暴露矩阵（CANJEM）。
在蒙特利尔进行了四项大型癌症病例对照研究，旨在通过详细访谈评估职业暴露情况，并由专家评估可能的职业暴露情况。使用包含在 http://expostats.ca/chems 上的 258 种物质（按流行率列出）的清单评估了 31673 种工作。这个大型暴露数据库被配置为 JEM。
CANJEM 有四种职业分类系统。它提供了特定职业工人暴露的概率估计，以及对于暴露的工人，各种暴露指标的估计。CANJEM 可以在线（www.canjem.ca）或批量版本访问。
CANJEM 是一个大型的回溯性暴露信息来源，涵盖了大多数职业和许多物质。CANJEM 可用于支持流行病学和职业健康中的暴露评估工作。
