The Clinical and Biochemical Study of Pesticide Sprayers

Clinical, haematological and biochemical studies of 34 subjects, occupationally exposed to different types of pesticides, were conducted. The findings have been compared with those observed in 14 control subjects. Inhibition of cholinesterase activity was observed in the exposed group. Serum alkaline phosphatase was also found to be raised. Radiological examination revealed pneumonitic patches in the chest skiagrams of three exposed subjects. Paraesthesia with hyporeflexia was also found in 8.8% of exposed subjects. The findings suggest that exposure to multiple pesticides over many years affects the normal functioning of different organ systems and may produce characteristic clinical effects.
