炼砒遗址土壤及植物总砷分布的特征

The Characteristic Distribution of Total Arsenic in the Soll and Plants around the Arsenic Smelting Ruins

在炼砒遗址的河流两岸，土壤受砷污染严重，含砷量比一般土壤高１～２个数量级。该区域的植物含砷量也比其它地区高。但砷在土壤中的分布和在植物各部位的分布仍然是有规律的。

he soil on the banks of the Lauhu chong river running through the arsenic smelting ru-ins is very seriously polluted with arsenic. The amount of arsenic is one to two orders of magni-tude higher than that in the natual soil.The plants in this area has also very high concentration ofarsenis. The concentration of total arsenic in the soil and in various parts of the plants exhibit aregular distribution pattern. These data provide a fundamental basic for the further study of theplants in the response of arsenic pollution.
