农产品中噻苯隆的残留现状、降解特点及分析方法进展

噻苯隆是一种具有生长素和细胞分裂素活性的苯基脲类植物生长调节剂,在农产品生产中合理使用可起到增加产量、改善品质的作用。但是,随着噻苯隆的大量使用,其在农产品中的残留问题逐渐显现,由于对哺乳动物存在一定的毒性风险,许多国家针对噻苯隆都制定了严格的限量标准,对噻苯隆残留降解、检验检测等方面的研究也日益增多,但缺乏对近期已有研究成果的比较系统全面的综述。本文介绍了近几年我国农产品中噻苯隆的残留现状,总结了不同农产品中噻苯隆的降解特点,综述了噻苯隆的主要检测方法,以及各方法在实际检测应用中的优缺点,并对噻苯隆今后的研究工作提出建议,旨在为农产品生产中合理规范使用噻苯隆以及建立农产品中噻苯隆快速、高效和精准的残留检测方法提供参考。

Residue status, degradation characteristics and analytical methods of thidiazuron in agricultural products

Thidiazuron is a phenylurea-derivative plant growth regulator with auxin- and cytokinin-like activity. The reasonable application of thidiazuron can increase the yield and improve the quality of agricultural products. However, extensive use of thidiazuron has contributed to the contamination of agricultural products. Due to the toxicity risk to mammals, many countries have set strcit maximum residue limits for thidiazuron in agricultural products, and the researches on degradation and detection of thidiazuron residues are also increasing, but systematic and comprehensive review articles are emergent, especially for the recent literatures. This paper described the residue status of thidiazuron in agricultural products in China in recent years, summarized the degradation characteristics of thidiazuron in different agricultural products, reviewed the main detection methods of thidiazuron, as well as the advantages and disadvantages of each method in the detection of real samples, and put forward several suggestions for the further study on thidiazuron, in order to provide references for standardizing the use of thidiazuron and establishing rapid, efficient and accurate methods for determining thidiazuron residues in agricultural products.
