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(shù)及其產(chǎn)品能否獲得足夠的研究空間和良好開發(fā)市場(chǎng)的關(guān)鍵所在.然而,在重視安全性的同時(shí),也必須認(rèn)識(shí)到轉(zhuǎn)基因技術(shù)及其產(chǎn)品的出現(xiàn)乃是人類社會(huì)發(fā)展的客觀必然.當(dāng)務(wù)之急不應(yīng)該是簡(jiǎn)單地反對(duì)或者贊成,而是必須對(duì)轉(zhuǎn)基因產(chǎn)品進(jìn)行全面、充分的研究和客觀、具體的評(píng)價(jià),從而使其在造福于人類的同時(shí),能有效地減少或避免對(duì)人類健康及其生存環(huán)境可能產(chǎn)生的潛在危害.當(dāng)然,對(duì)社會(huì)公眾進(jìn)行科普宣傳和指導(dǎo),從而使其在對(duì)轉(zhuǎn)基因產(chǎn)品具有客觀了解的基礎(chǔ)上培養(yǎng)一種健康的接受心態(tài)也是必要的.本文在簡(jiǎn)述轉(zhuǎn)基因產(chǎn)品安全性及其研究現(xiàn)狀的基礎(chǔ)上,提出若干對(duì)應(yīng)策略,希望能引起社會(huì)各界的共識(shí)。
