[Five years' epidemiologic study of intoxication of pesticide use in a county]

The Intoxication of Pesticide Use (IPU) in a county since 1984-1988 was studied 1,345 cases of intoxication were found and two of them died among 732,128 persons investigated during those five years. The incidence rates of IPU were 0.410 8%, 0.166 7%, 0.052 1%, 0.205 7% and 0.090 5% respectively. Analysis on the relationship between the IPU and air temperature showed that they had a positive correlation (r = 0.886, P less than 0.01), indication that air temperature was one of important factors that affected the occurrence of IPU. Suggestions were made for the prevention of IPU.
