Title Occupational paraquat exposure of agricultural workers in large Costa Rica farms
Bibliographic information Mar. 2009, Vol.82, No.4, p.455-462. 20 ref.
Abstract This study determined the extent of occupational exposure to paraquat among farm workers in Costa Rica. 24h urine samples were collected from 119 paraquat handlers and 54 non-handlers from banana, coffee and palm oil farms. Information about herbicide handling operations was also collected. The urinary paraquat levels were determined by an enzyme-linked immunosorbent assay (ELISA). Inhalable dust and airborne paraquat levels were also measured for a subset of the participants. Paraquat levels were non-detectable or very low among workers not handling paraquat. For handlers, 83.3%, 47.1% and 63.9% of the samples were below detection limits before, during and after spray days, respectively. Other findings are discussed.
