预防中毒性疾病，首先要求减少与毒物的接触，识别机体的遗传易感性，　并尽早发现不可逆性损害前的有关生理生化改变。尽管在环境医学领域应用神　经毒性生物标志物意义重大，但应用标志物评价接触、效应及易感性研究却比　其他领域进展缓慢，其中主要影响因素为神经系统功能 To prevent toxic diseases, we must first reduce the contact with poison, identify the genetic susceptibility of the body, and early detection of irreversible damage before the relevant physiological and biochemical changes. Although the use of neurotoxic biomarkers in the field of environmental medicine is of great significance, the use of biomarkers to evaluate contact, effect and susceptibility studies has progressed more slowly than in other fields, with the main influencing factors being neurological function
