本文对某硫酸厂磷肥车间化成、混化、吸收工段的劳动卫生状况及工人健康情况进行了调查。结果表明,磷肥车间氟化物浓度高出容许标准2.5～16.5倍。作业工人的鼻部疾患、牙齿酸蚀症等口腔疾病惠病率比对照组显著增高,但龋齿惠病率比对照组明显降低(P<0.001)。肺部疾患也比对照组增高(P<0.05)。接触氟化物的浓度高、工龄长,口腔疾惠的患病率增高。
In this paper, the sulfuric acid plant phosphate fertilizer workshop into, mixing, absorption of labor and health conditions and workers were investigated. The results showed that the phosphate fertilizer plant fluoride concentration higher than the allowable standard of 2.5 to 16.5 times. The prevalence of oral diseases such as nasal disorders and dental erosion in workers was significantly higher than that in the control group, but the prevalence of dental caries was significantly lower than that in the control group (P <0.001). Lung disease also increased compared with the control group (P <0.05). Exposure to high concentrations of fluoride, long service life, the prevalence of oral gain increased.
