Abstract: Many health problems were caused due to the lack of useful elements in the human body or toxic elements excessive,trace elements play a pivotal role in the study of medical geology. With the deepening of the medical geological research and the rapid development of new technology,the areas of research and study the extent of the trace elements was also expanding and deepening. This paper reviews the main contents of trace elements in medical geology,including the bioavailability of trace elements,the interaction between trace elements,exposure pathways of trace elements in the human body and its toxicokinetic; describes the environmental geochemistry and ecotoxicological methods, multivariate statistics and geostatistics in the study of the use of trace elements; compares and summarizes nemerow index method,geological cumulative index,potential ecological risk index,environmental health risk assessment( EHRA) and based on the life cycle of human health risk assessment and other risk assessment methods. Based on which,pointed out that the weakest link in the study of the field as well as the future direction of development,and to promote further research.
