Abstract Botanical garden workers are subject to health hazards resulting from their exposure to pesticides in confined spaces such as greenhouses. In this study, the behaviour of foliar residues was evaluated for several representative pesticides between the time of application and of the re-entry of workers in the greenhouses. Skin exposure risks were evaluated by a hand washing method as well as through the use of a fluorescent marker. Workers' total exposure was determined by measuring urinary metabolites excreted over a post-exposure period of 24 hours. Cholinesterase activity variations were measured in cases where organophosphorus insecticides were applied. Results show that workers remain exposed when returning to greenhouses the day after applying pesticides. However, the levels of exposure measured are generally low. Use of gloves would allow to further decrease the level of exposure. Several other preventive measures are proposed.
