Soil pollution will be harmful to ecological system and human health,and hence the formulation of the soil pollution grade standard is very important.

So these contaminated soils need to be amended imminently.

In order to evaluate chemical behaviors and bioavailability of heavy metals in contaminated soils,two types of topsoil samples were collected at a Pb-Zn mining area located in Chenzhou city,southern Hunan Province(southern China),where mining activities of heavy metals have been conducted for about 500 years and ore waste tailings have been piled up around.

Because of the problem of the polluted soil is more and more serious, its treatment technologies become the focuses on the world.

The authors provided an overview of established or standardized earthworm tests,including toxicity test,survey of population dynamics,avoidance test,bioaccumulation test and biomarker test,and gave a brief introduction to their application in monitoring and risk assessment of soil contamination.

In this paper, general situation of soil contamination and its controlling.

Three guidelines are set forth for evaluation of soil contamination at the scale of a region or a specific site in view of ambiguity of the definition for soil contamination at present.
