基于转基因产品成分低水平混杂问题探究我国转基因阈值制度

随着全球经济贸易一体化发展，转基因产品商业化为多边国际贸易带来无限的机遇和挑战。随之而来的转基因低水平混杂（LLP）问题作为不可规避的现实问题，成为国际贸易中的前沿议题。转基因阈值制度作为国际社会缓解转基因低水平混杂问题的重要因素，逐渐引起各国政府关注。以转基因低水平混杂问题现状为立足点，从技术和政策层面分析了建立转基因阈值制度对于我国完善转基因低水平混杂法律制度及配套长效机制的必要性，从标识制度和LLP阈值制度两个角度概述了转基因阈值制度在维护本国生物安全和贸易顺畅等方面的双重作用，旨在为我国完善转基因低水平混杂法律制度和开展定量检测标准制定工作提供参考。

Research on the Transgenic Threshold System in China Based on Low­level Presence of Genetically Modified Products

With the development of global economic and trade integration， the commercialization of genetically modified （GM） products brings infinite opportunities and challenges to multilateral international trade. As an unavoidable practical problem， the low-level presence （LLP） of GM products has become a frontier issue in international trade. As an important factor for the international community to alleviate the problem of low low-level presence （LLP） of GM products， the transgenic threshold system has gradually attracted the attention of governments around the world. Based on the current situation of low-level presence of GM products， this paper analyzed the necessity of establishing GM threshold system to optimize the regulation system and its related long-term mechanism in China from the technical and policy aspects. From the perspective of GM products labeling system and LLP threshold system， this paper summarized the role of GM threshold system in maintaining national biosafety and smooth trade. This paper would have reference value to improve the GM threshold system and develop quantitative testing standards.
