摘要
以石家庄市显像管玻壳厂排放的铅尘为研究对象 ,通过在该玻壳厂周围土壤布点采样 ,较系统地研究了铅尘在大气和周围土壤中的迁移和转化规律。研究表明 ,用高斯模式能成功地预测铅尘在大气中的迁移扩散规律 ;玻壳厂周围土壤表层铅含量较大值出现在当地年主导风向 ( SSE.N)下风向 ;铅在土壤中的分布主要集中在 0～ 2 0 cm的耕作层 ,在 2 0～ 40 cm深度范围内 ,铅含量呈下降趋势 ,最大降幅达 5 0 %。
By laying out and sampling on the soil round the glass shell of kinescope factory,this paper has systematically studied the movement and dispersion rules of lead dust which was given off from the chimnies in the factory.The study showed that Gauss model could successfully forecast the rules of movement;the more lead on the surface soil round the factory appeaned in the leeward of local dominant wind direction(SSE,N);and dispersion in the atmosphere and lead in the soil mainly distributes in 0～20cm tilith layer,the lead fell down in the depch of 20～40cm,the maxinal rang reached 50%.
