[Examination of persons in contact with plant protection and pest control agents]

It is referred to the great importance of the annual controls of farmers who work with preventive remedies for plants and insecticides. Alone during a two-year control 4-7 per cent of disabled persons and 15-18 percent who needed by all means a control were found. Among the laboratory values, apart from the quantitative determination of cholesterinase, above all the determination of the transaminases, the thymol test and the G-6-PhD stood the test. These examinations must by all means be carried out already before the beginning of the work. The number of persons who have to be controlled must be enlarged. Publications concerning other results hitherto yielded and the consequences which must be derived from this are desirable.
