Abstract:
Acute toxic effects from pesticides are fairly easily recognized, whereas the effects that result from long-term exposure to low doses are often difficult to distinguish. The chronic pesticide poisoning may occur theoretically, but as for the reported cases of pesticide poisoning and disorders the majority are generally acute pesticide poisoning and skin lesions.
To make a proposal for the study of the chronic pesticide poisoning and disorders, the author have discussed about the subjects of general speech in the annual meeting of the Japanese Association of Rural Medicine and some nationwide reports on the chronic effects from pesticides. From the results, there are many controversial points to be improve as the confusion of the concepts and terminology used, overestimation of the decrease in serum and plasma cholinesterase activity for diagnosis of pesticide poisoning, fairly limited epidemiological study for evaluation of the chronic health effects associated with pesticide exposure, and so forth.
Many detailed studies will be recommended as the following:
1) Establishment of the approaches to causal relationship between situation of pesticide exposure and health effects; 2) To seize the exposure levels of pesticides in the presentand the past; 3) The development of the methods of accurate examination and diagnosis, and their concrete application to a field study; 4) Establishment of the better designed of epidemiological study; 5) Enforcement of systematic study of health effects of occupational groups exposed to pesticides for long periods; 6) Establishment of the appropriate methods of toxicity testing and their well fitted extrapolation to health effects; 7) Opening to the general public of data on the toxicity testing and on the survey in an enterprise; 8) Cooperation and collaboration in studying among researchersand field workers, and others.
