The preliminary selection,identification,classification and assessment of acute bio-toxicity and genetic toxicity for more than 40 kinds of major solid wastes in major industries of Shenyang city have been done. In acute toxicity identification,the little white mouse method and lightion bacteria method have been used for the dividing of toxicigy degree. In genetic toxicigy,the broad bean root tip cell micro-nuclear technique has been used for toxicity selection and degree dividing.
