Abstract:

Abstract Mercury pollution of atmospher, soil and horticultural plants in the vicinity of a clinical ther-mometer factory was investigated. The results showed that mercury pollution of atmospher and soil de-creased with the extension of distance from the contaminative sourece. The relative formula between air pol-lution and distance was Y= 0. 1076 - 0. 0015 ln X. The relative formula between soil pollution and distancewas Y= 14456. 3319. X-1.9103. It was found that mercury contents of soils for horticultural use were 6 timeshigher than that for agricultural use. Suggestion about tree planting around a mercury polluted zone was alsopresented in the thesis.

摘要：

 考察了体温计厂附近大气、土壤和园林植物受汞污染危害的情况,发现大气汞的污染与距离的关系式为y=0.01076—0.00151nx,土壤污染与距离的关系式为y=14456.3319·X-1.9103.研究指出园林土壤的含汞量为农业土壤的6倍.在汞污染源四周栽植常绿乔灌木是限制汞污染扩散的有效途径.
