目的通过对某电解铝厂不同居民点人群尿氟测定,研究铝业生产对周边环境的影响程度,从而确定铝业在城市居民点的定位。方法采集我区某电解铝厂不同方向和远近不同的居民点人群,测定其尿氟含量,并进行比较分析。结果北、南两组尿氟(x±s)分别为(0.83±0.31)、(0.55±0.24)、(mg/L),北组明显高于南组(P<0.01);北边同方向1公里、5公里不同距离组分别为(0.83±0.31)、(0.45±0.21),近组明显高于远组(P<0.01)。结论下风侧(北组)明显高于上风侧(南组);近厂居民点受到影响较明显。
Objective To determine the influence of aluminum production on the surrounding environment by measuring urinary fluoride in different settlements of an electrolytic aluminum plant and determine the positioning of aluminum industry in urban settlements. Methods A population of residents in different residential areas with different orientations and distances in an electrolytic aluminum plant in our district were collected and their urinary fluoride contents were measured and compared. Results The urinary fluoride (χ ± s) in the north and south groups were (0.83 ± 0.31) and (0.55 ± 0.24) mg / L respectively, significantly higher in the north group than in the south group (P <0.01) (0.83 ± 0.31) and (0.45 ± 0.21), respectively, in the distance of 5km and 5km respectively in the distance group and the distance group (P <0.01). Conclusions The leeward side (North Formation) is obviously higher than the upper windward (South Formation); residential settlement in Near Plant is more obvious.
