一些调查者发现工业排放的氟化物导致儿童牙齿发生斑釉,但可降低儿童龋齿的发病率。其中两项调查中X线检查发现有骨骼改变。多数报告指出尿氟未受影响。有两项调查描述了血液学改变。三项调查发现对呼吸系统有影响。某些调查中报告饮水、空气和尿中氟含量多数为正常值,骨骼、牙齿、血液、肺及其它系统异常的起因是否为氟化物尚不清楚。call等从接触工业排放的氟化物居民的软组织活检中未发现异常高的氟浓度,但其接触量不详。Mur
Some investigators have found that industrial emissions of fluoride cause spot glazes in children’s teeth but can reduce the incidence of dental caries in children. Two of the findings of the X-ray examination revealed skeletal changes. Most reports indicate that urinary fluoride is not affected. Two surveys described hematological changes. Three investigations revealed effects on the respiratory system. In some surveys, the majority of fluoride levels in drinking water, air and urine were reported as normal, and the cause of abnormalities in bone, teeth, blood, lungs, and other systems is not known as fluoride. No abnormally high concentrations of fluoride were found in the soft tissue biopsies of fluoride inhabitants exposed to industrial exposure, such as call, but their exposure was unknown. Mur
