The present paper is to make a retrospect of the latest ad- vances over the research of the heavy metal pollution to the environ- ment, such as lead and cadmium. Since they are widely used in dif- ferent areas of the national economy and bring about pollution and contamination to the living environment and food stuff due to their toxicity they contain. Therefore, great attention should be paid nowa- days to the identification of the sources of pollution and defining of the spreading history of the heavy metal contaminants. However, it is not easy to pinpoint the sources of heavy metal pollutants because much more heavy-metal pollution sources are situated in the typical urban settings rather than in the countryside. As a matter of fact, all the environmental media exist in nature in the mixtures of metals and other materials, and most of metals are often introduced into the envi- romnent as mixtures. So far as the technology of identification and ap- portionment of heavy metal pollution sources is concerned, there ex- ists a series of methods for heavy metal sources qualitative/quantita- tive analysis which may play a very important role in controlling the environmental pollution and already get mature and turn to be the relevant laws and policies. In order to reduce the exposure level of such metals to human body, effective measures should be taken to i- dentify heavy metal sources in a safe way and control them efficiently. While introducing the receptor model, one of the most commonly used methods to identify and quantify the harm of contaminant emission of the metals, great advances in identification and apportionment of heavy metal pollution in environment have also been made during these years. The paper also outlined the basic principles, characteris- tics and applications in this way, and finally raised the unresolved questions in recent researches and its prospects. And, finally, the aim of this paper was also to provide a theoretical and technical sup- port for further relevant studies and environmental
