工厂的氟污染对蔬菜含氟量的影响
- EFFECT OF FLUORIDE POLLUTION ON VEGETABLE FLUORIDE CONTENT
- 摘要：上海某厂生产氟利昂和氢氟酸等化工产品,排放的废水、废气中含有大量氟化物。该厂排放的废气中氟化氢的量相当于全市氟化氢总排放量的50％左右。
- Abstract：The investigation on the fluoride pollution in the suburbs of Shanghai indicated that the air, water and vegetables in the area near certain emission sources (within 1000m) were polluted. Visible symptoms of fluoride pollution were observed on garlic, leek and Chinese chives. For those resistant species, such as Chinese cabbage, lettuce and celery, the fluoride contents were detected to be higher than permitted level of 1 mg/kg, while no visible symptoms were observed. There are significant correlations between fluoride contents of air,water,dust, soil and vegetables and with the increase of distance from the emission sources, fluoride concentrationsdecreased.
