The results showed: Fragilaria brevistriata had the highest average difference in temperature to respond to heavy metals, it was 0.24 ℃ that was 0.05 ℃ high more 0.19 ℃ of together average difference in temperature of eight kinds of algae to respond to heavy metals; The percent of Fragilaria brevistriata responding better to the reagents was 80% that was the highest in eight kinds of algae; The average response time of Fragilaria brevistriata responding to the reagents was 4.65 min that was low more 5.21 min of together average response time of eight kinds of algae; Fragilaria brevistriata' sensitivity was between 0.06 mgL^(-1) and 7.0 mgL^(-1), and the luminescent bacteria' sensitivity was between 0.07 mgL^(-1) and 15.3 mgL^(-1), so Fragilaria brevistriata had lower dose to respond to the heavy metals.

结果表明：平均响应温差短线脆杆藻最大，为0.24℃，高出8种藻的0.19℃总平均温差0.05℃；较好药品响应率短线脆杆藻最高，为80%；平均响应时间短线脆杆藻居中，为4.65min，低于8种藻的总平均响应时间5.21min；短线脆杆藻对重金属的灵敏度在0.06~7.0mgL^(-1)之间，发光细菌在0.07~15.3mgL^(-1)之间，表明短线脆杆藻对重金属响应的剂量低。

In this paper the method of distinguishing background content and polluted content for As element of soil based on Hazen probability curve in Tongling diggings were discussed.
