Abstract : currently , biosafety has become a key to transgenic technique and its products , which gain enough research space and better exploiture market or not . then , as well as we pay attention to the security , we should realize that transgenic technique and its products are essential result in human society . today , they would not simply oppose or praise gmos , but we should carry out thorough studies and estimate without influence by human feelings , so that the technique and the products are used for the benefit of mankind , not doing harm for human health and the environment . of course , we should provide some essential scientific knowledge and guidance for public people . in the paper , we will put forward some suggestions on the base of analysing transgenic products 摘要目前,生物安全性问题已成为转基因技术及其产品能否获得足够的研究空间和良好开发市场的关键所在.然而,在重视安全性的同时,也必须认识到转基因技术及其产品的出现乃是人类社会发展的客观必然.当务之急不应该是简单地反对或者赞成,而是必须对转基因产品进行全面、充分的研究和客观、具体的评价,从而使其在造福于人类的同时,能有效地减少或避免对人类健康及其生存环境可能产生的潜在危害.当然,对社会公众进行科普宣传和指导,从而使其在对转基因产品具有客观了解的基础上培养一种健康的接受心态也是必要的.本文在简述转基因产品安全性及其研究现状的基础上,提出若干对应策略,希望能引起社会各界的共识。
