[Effects of controlling specific dangerous pesticides on prevention of acute pesticide poisoning in rural area].

Objective: To investigate the effects of controlling the specific dangerous pesticides on prevention of acute pesticide poisoning in rural area.

Methods: The data of reported cases of pesticide poisoning were analyzed to find out the specific dangerous pesticide in acute pesticide poisoning. Then the occurrence of occupational pesticide poisoning and fatality of non-occupational pesticide poisoning were estimated under the hypothesis of removing the specific dangerous pesticides.

Results: The data indicated that parathion (including methyl parathion) was the specific dangerous pesticide inducing occupational pesticide poisoning. After removing the use of parathion, the hazard of pesticides which caused occupational pesticide poisoning would be significantly decreased (P < 0.01). Parathion was also the most dangerous pesticide which caused non-occupational pesticide poisoning, with its fatality up to 15.8%. If parathion was well controlled, the fatality of non-occupational pesticide poisoning would be declined from 9.4% to 7.4%. The analyses of related literatures also revealed the similar results.

Conclusion: The occurrence of occupational pesticide poisoning and fatality of non-occupational pesticide poisoning may decrease if the most dangerous pesticides are well supervised.
