化肥厂周边地区植物叶片中氟的积累

Accumulation of fluoride in leaves of plant around chemical fertilizer plant

采集了吉林市某化肥厂周边的植物叶片样品,对叶片中的氟化物进行测定,以评价其周围空气环境中氟化物的污染状况.实验结果表明,在距化肥厂500 m内,随着距离的增加,植物叶片样品中氟含量明显减小,并呈良好的线性关系.而在1 000 m左右时,氟含量与500 m处相近,周边环境影响因素比较复杂.

Samples of plant leaves are collected around the Chemical Fertilizer Factory in Jilin City. The fluoride in the samples is determined, and its pollution in the air is evaluated. The experimental results indicate that within the distance of 500m from the factory ,the fluoride content in samples is inversely proportional to the distance. And the fluoride content in the samples collected in the distance of 1000m from the factory is closely same to the fluoride content in ones collected in the distance of 500m from the factory. The environmental factors around the factory are very complicated.
