[Health effects and personal protection in pest control workers using organophosphorus insecticides].
One hundred and sixteen pest control workers (16 termite control workers (Sprayer I), 46 cockroach or fly-control workers (Sprayer II) and 56 both termite and cockroach or fly-control workers (Sprayer III)) were surveyed by a questionnaire and health examinations. Variety and quantity of pesticide used, personal usage of protective devices (respirator, gloves, work clothes, under wear), and conditions related to bathing were studied by a questionnaire. Relationships between protective devices and blood cholinesterase activity (ChE) were also analyzed. Significant findings were as follows: Most of the pest control operators wore gum gloves and gas masks when involved in termite control. However in the case of cockroach or fly-control, 38% did not wear gloves, and for respiratory protection 44% wore gas masks while 25% of them did not even use any form of respirators. In spite of having better protective practices than sprayers II and III, sprayer I showed significantly lower plasma ChE activity than both sprayer II and III. Plasma ChE activity in sprayers who put on simple respirators tended to be lower than those using gas masks. Plasma ChE activity was also significantly lower in those workers who had less frequent changes of work clothes compared to those with more frequent.
