摘　　要：以保障我国茶叶质量安全、饮茶者健康和国际公平贸易为目的,针对茶叶中最大残留限量(MRLs)制定的科学性、农药和污染物控制技术和检测技术。历经30余年研究,首创了茶汤“有效风险量”决定原则,重构了茶叶中农药最大残留限量标准制定的国际规范;探明了残留量的关键控制点,创建了农药选用、使用和污染物源解析控制技术;突破了现场检测和精准检测难点,研发了检测技术和产品,构建了“MRLs制定、残留控制、识别检测”为核心技术的茶叶中农药残留和污染物管控体系并应用推广,推动了我国茶产业绿色发展的科技进步。In the past 30 years,to solve three problems involved in quality and safety of tea,namely how to set the scientific maximum residue limits(MRLs)in tea,how to control the pesticide and contaminant residue,and how to improve detection method,the principal of“effective risk assessment”by using tea infusion was innovated.Based on that,the principal of global MRLs on tea was reconstructed.The key point in the control of pesticide residues and important contaminants was revealed,and the selection principal and application technology of pesticides were established.The in-situ and high-throughput analytical methods for pesticides and contaminants in tea were developed.The control system based on“MRLs fixation,residue control and recognition detection”was constructed and popularized.These work would promote the scientific and technological progress of the sustainable development of tea industry in China.
