The use of personal protective equipment (PPE) by workers who sprayed paraquat was studied and the protective effect was assessed by measuring urinary levels in 119 workers and by interviewing workers on symptoms previously experienced. Use of PPE was not significantly associated with self-reported health symptoms, while the measured levels of paraquat showed a slight protective effect from the use of coveralls. No similar association was found for other types of PPE.
