Description

Effect of Chlordimeform on Cardiovascular Function in Occupational Exposures: Zhijun ZHOU, et al. Department of Occupational Health, Shanghai Medical University—To understand the possible effects of an insecticide, chlordimeform, on the human cardiovascular system, this work was carried out. Pre- and postexposure, the medical examinations, especially cardiovascular functions, were meticulously done in farmers spraying 0.125% solution of chlordimeforme for 3 consecutive days and packers packing chlordimeform for one month. The exposure level was measured by means of the urinary excretion of chlordimeform and its main metabolite, 4-chlor-o-tolumidine, as well as the air concentration in the work place and skin contamination by using a regional proportional sampling strategy. The alterations, though mild and diverse, were significant compared to their own pre-exposure background. The changes in heart rate, blood pressure and some EKG parameters, such as T wave, P wave, PR interval and Qt interval were noticed. The cardiovascular functional changes were usual and sensitive findings in the exposed persons, and their importance in health surveillance needs to be emphasized.
