Apple Growers’ Skin Exposure to Pesticides

  • December 05, 2019

The Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST) has just published a study describing apple growers’ skin exposure while performing their main tasks related to mixing and spraying pesticides and their use of protective clothing. Based on a review of the literature, extensive field observations and repeated interviews with five growers, the researchers conducted a detailed analysis of exposure situations and factors that facilitate or interfere with the wearing of protective clothing.

Occupational Exposure to Bioaerosols When Using Biological Degreasing Stations

  • November 07, 2019

To clean oily or greasy parts in mechanical maintenance shops, workers use biowashers or biological degreasing stations. The degreasing agents in these washing stations contain bacteria for which no metrological data were available for assessing the occupational risk of exposure through inhalation. To address this lack of data, the researchers monitored five biological degreasing stations for a year, taking 50 mL samples of degreasing fluid every two months and, for comparison purposes, an initial sample of unused degreaser from each station. Using a variety of methods, the researchers counted and identified the bacteria that colonized the degreasers. They detected 60 species of bacteria at concentrations ranging from 3.6 x 104 to 2.6 x 107 CFU/mL in the used fluids, whereas only one species, Bacillus subtilis, was found in the unused fluids.

A Program To Improve the Return to Work of Injured and Depressed Workers

  • October 31, 2019

Many workers who have been injured on the job present symptoms of pain and depression, which can have negative effects on their recovery. Symptoms of depression can hinder a person’s ability to perform many important activities of daily living, including occupational activities. Studies have shown that injured workers with symptoms of depression remain off work twice as long as those who are not depressed. Interventions used to treat pain in injured workers are clearly less effective when they also present symptoms of depression.
