【Abstract】 The major health hazard in chlorothalonil manufacturing workshop was caused by direct contact with chlorothalonil powder. Dust concentration of 30 samples collected from 5 work-places were as follows. The maximum value was 1.4lmg/m3,the mean value 0.2mg/m3 and no chlorothalonil could be detected in 12 samples. In a leather factory where chlorothalonil water suspension was used for anti-fungus, chlorothalonil was not found out in the air of work-place. No systemic disturbances were found in chlorothalonil exposed workers during more than three years of observation. The chief complaint of the exposed workers was skin lesions. The data of skin patch test and the clinical manifestation correspond to the allergic contact dermatitis. The positive patch test rate of the workers at the leather factory (73.3%) was higher than that of manufacturing workers (2.5%-5.0%). It is obvious that skin exposure is the most important cause for skin lesion. So that effective skin protection should be taken for chlorothalonil exposed workers.更多还原
