Abstract: Salithion, an agricultural chemical, was sprayed in persimmon orchards. The exposure of salithion to workers' bodies and the amount of salithion in the blood were measured.
The orchards were situated in the Tataki area of Tanbara-cho, Shuso-gun, Ehime prefecture. Before spraying, the salithion solution was diluted 1, 000 fold.
The amount of salithion exposed to the skin of the sprayers was estimated by the measured amount of salithion on the gloves, socks and filter paper that was put on their underwear. The results were as follows.
1) The mean amount of salithion exposed to the body surface of the sprayers who were protected perfectly was estimated to be 0.54 mg. On the other hand, the exposure to the sprayers protected imperfectly was 8.02 mg. The latter value was 15 times higher than the former, and the difference was statistically significant (p<0.05).
2) The concentration of the salithion in the blood of the sprayers was 11.5±13.8 ppb (M±SD). The correlation coefficient between salithion concentration in the blood and the amount of salithion exposed to the body surface was r = 0.73 (p<0.01).
