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,生物安全性問題已成為轉(zhuǎn)基因技術及其產(chǎn)品能否獲得足夠的研究空間和良好開發(fā)市場的關鍵所在.然而,在重視安全性的同時,也必須認識到轉(zhuǎn)基因技術及其產(chǎn)品的出現(xiàn)乃是人類社會發(fā)展的客觀必然.當務之急不應該是簡單地反對或者贊成,而是必須對轉(zhuǎn)基因產(chǎn)品進行全面、充分的研究和客觀、具體的評價,從而使其在造福于人類的同時,能有效地減少或避免對人類健康及其生存環(huán)境可能產(chǎn)生的潛在危害.當然,對社會公眾進行科普宣傳和指導,從而使其在對轉(zhuǎn)基因產(chǎn)品具有客觀了解的基礎上培養(yǎng)一種健康的接受心態(tài)也是必要的.本文在簡述轉(zhuǎn)基因產(chǎn)品安全性及其研究現(xiàn)狀的基礎上,提出若干對應策略,希望能引起社會各界的共識。
