Indicators of occupational pesticide exposure are associated with psychiatric symptoms

Abstract

In southeastern Spain, intensive and highly productive agriculture under plastic also poses a risk to human health, as evidenced by reports on acute pesticide poisoning and its effects on mental health. However, knowledge of chronic exposures and their relationship to psychiatric disorders is still limited. This study analyzed the relationship between occupational exposure to pesticides and psychiatric disorders in farmers from Almería. A cross-sectional study was conducted amongst a coastal population in Almería, where over 32,800 ha of land are dedicated to intensive agriculture in plastic greenhouses. A total of 409 people participated in the study: 203 farmers and 206 control subjects. The highest risk of psychiatric disorders was observed in farmers living in areas of high exposure to pesticides, working in greenhouses (intensive agriculture), without protective goggles and without wearing masks. This study supports previous evidence of an elevated risk of psychiatric disorders among farm workers exposed to pesticides.
