Urinary fluoride concentrations have been measured in electric arc welders using basic electrodes. The fluoride concentration and the total welding fume concentration in air showed a linear relation with postshift urinary fluoride concentration. The measured concentrations were below internationally recommended postshift urinary fluoride concentrations believed to cause fluorosis. Biological monitoring by postshift urinary fluoride measurements is evaluated for the prediction of total welding fume exposure, when a specific basic electrode was used, by means of confidence limits and tests of validity.
已对使用碱性焊条的电弧焊工的尿氟浓度进行了测量。空气中的氟化物浓度和总焊接烟尘浓度与下班后尿氟浓度呈线性关系。所测浓度低于国际上认为会导致氟中毒的下班后尿氟推荐浓度。通过置信限和有效性检验,评估了利用下班后尿氟测量进行生物监测以预测使用特定碱性焊条时的总焊接烟尘暴露情况。
