residue level persistence and safety of spirodiclofen pyridaben mixture in Citrus Fruits
Food Chemistry, 2016Co-Authors: Dali Sun, Yanmei Zhu, Junxiao Pang, Zhiqin Zhou, Bining JiaoAbstract:Abstract A sample pretreatment method was established to analyze the residues of spirodiclofen–pyridaben mixture in Citrus Fruits using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC–MS/MS). A mixed formulation of 27% spirodiclofen–pyridaben suspension concentrates was sprayed on Citrus in field conditions at 1- or 1.5-fold recommended dose. The dissipation of spirodiclofen–pyridaben mixture in whole Citrus follows the first-order dynamic equation with half-lives of 4.56–13.1 d at three locations. Residues of spirodiclofen–pyridaben mixture are mainly distributed in peel, followed by whole Citrus and pulp. Risk assessment showed that spirodiclofen exerts much higher chronic risk than acute risk, while pyridaben exerts relatively lower chronic risk than acute risk. However, both chronic and acute risks of this mixed pesticide in Citrus Fruits are relatively low to humans irrespective of dosages, frequency of applications, and pre-harvest intervals. The residue dynamics information will support label-claim for use of this mixed pesticide in Citrus Fruits.

dissipation and residue of forchlorfenuron in Citrus Fruits
Bulletin of Environmental Contamination and Toxicology, 2013Co-Authors: Weijun Chen, Bining Jiao, Xuesu Su, Qiyang Zhao, Chengqiu WangAbstract:Field trials were carried out in three provinces of China to study the dissipation and residue of forchlorfenuron in Citrus Fruits. The results had shown that the degradation rate of forchlorfenuron in Citrus Fruits followed the first-order kinetics equation C = A·eBt. The half-lives of forchlorfenuron were 15.8–23.0 days, the final residues of forchlorfenuron in pulp were all ≤0.002 mg/kg, and most of the residues were concentrated in the peel. The risk assessment revealed that no significant potential health risk would be induced by forchlorfenuron in Citrus Fruits. Therefore, it could be safe to apply forchlorfenuron in Citrus Fruits, and the results of this study could also be regarded as a reference to the setting of maximum residue limit for forchlorfenuron in Citrus Fruits in China.
