Description of project

The purpose of this study was to assess the causes of death for Ontario Hydro/Hydro One Network Inc. forestry tradesmen based on duration of employment, exposure to specific herbicides, work location and to compare death rates in this trade group with those of the general population. This was a small manual search of the death records for those individuals who potentially could have been lost to follow-up. Later Canada participated in an international study coordinated by the International Agency for Research on Cancer. This study was carried out comprising 36 cohorts from 12 countries.
