Herbicide exposure during occupational knapsack spraying in French gardeners and municipal workers.

Context: There is a lack of data on pesticide exposure levels during spraying with a knapsack, while it could have important implications for their users' health.

Methods: We assessed levels and determinants of exposure in 24 male private landscapers/gardeners and municipal workers in France in 2011. Actual dermal exposure to glyphosate was assessed with cotton undergarments and gloves, and a cotton coverall changed between mixing and spraying to assess the contribution of each phase and body area to overall contamination.

Occupational exposure to pesticides and central nervous system tumors: results from the CERENAT case-control study.

Background: The etiology of the central nervous system (CNS) tumors remains largely unknown. The role of pesticide exposure has been suggested by several epidemiological studies, but with no definitive conclusion.

Objective: To analyze associations between occupational pesticide exposure and primary CNS tumors in adults in the CERENAT study.
