摘要

进行了一项田间研究,以了解七种不同杀虫剂(即四氟虫腈 200 SC、甲氨基阿维菌素苯甲酸盐 5 SG、虱螨脲 5.4 EC、茚虫威 14.5 SC、噻虫嗪 75 WP、丙溴磷 50 EC 和氯氰菊酯 25 EC)在花椰菜凝乳中/上的消散率以及各种清洗处理对其残留的影响。结果表明,四唑酮、苯甲酸阿维菌素、虱螨脲、茚虫威、噻虫嗪、丙溴磷和氯氰菊酯的初始沉积量(最后一次施用杀虫剂后,即 0 d)分别为 0.43、0.03、0.25、0.28、0.38、6.70 和 0.68 mg kg-1。所有测试杀虫剂的消散模式均遵循单相一阶动力学,半衰期分别为 6.25、8.85、3.27、7.71、4.36、2.98 和 3.76 d。建议这些杀虫剂的收获前间隔期分别为 6、9、3、8、4、3 和 4 d。所有去污技术都能降低残留水平。不过,用 5%碳酸氢钠水溶液浸泡处理后,花椰菜凝茎中的四唑酮、苯甲酸阿维菌素、虱螨脲、茚虫威、丙溴磷和氯氰菊酯残留量的最大降幅分别为 54%、42%、53%、48%、22%、54% 和 77%。其次是将花椰菜凝乳在 45-50 ° C 的水中浸泡 10 分钟,这可减少氯氰菊酯、丙溴磷、四氟虫腈、噻虫嗪、苯甲酸戊酯和氟苯脲的残留量。

Dissipation and evaluation of different treatments on the residues of different insecticides in/on cauliflower curd.

A field study to understand dissipation rates and effect of various washing treatments on the residues of seven different insecticides, i.e. tetraniliprole 200 SC, emamectin benzoate 5 SG, lufenuron 5.4 EC, indoxacarb 14.5 SC, thiodicarb 75 WP, profenofos 50 EC and cypermethrin 25 EC in/on cauliflower curd has been conducted. The results showed that initial deposits (just after the last insecticide application, i.e. 0 d) of tetraniliprole, emamectin benzoate, lufenuron, indoxacarb, thiodicarb, profenofos and cypermethrin were 0.43, 0.03, 0.25, 0.28, 0.38, 6.70 and 0.68 mg kg-1, respectively. The dissipation pattern of all the tested insecticides followed monophasic, first order kinetics with the half-lives of 6.25, 8.85, 3.27, 7.71, 4.36, 2.98 and 3.76 d, respectively. Proposed pre-harvest intervals for these insecticides are 6, 9, 3, 8, 4, 3 and 4 d, respectively. All the decontamination techniques showed reductions in residue levels. However, treatment by soaking in 5% sodium bicarbonate aqueous solution showed 54%, 42%, 53%, 48%, 22%, 54% and 77% maximum reductions in residues of tetraniliprole, emamectin benzoate, lufenuron, indoxacarb, profenofos and cypermethrin, respectively, in cauliflower curds. The next best treatment was soaking cauliflower curds in water at 45-50 °C for 10 min, which reduced the residues of cypermethrin, profenofos, tetraniliprole, thiodicarb, emamectin benzoate and lufenuron.

期刊介绍: Food Additives & Contaminants: Part A publishes original research papers and critical reviews covering analytical methodology, occurrence, persistence, safety evaluation, detoxification and regulatory control of natural and man-made additives and contaminants in the food and animal feed chain. Papers are published in the areas of food additives including flavourings, pesticide and veterinary drug residues, environmental contaminants, plant toxins, mycotoxins, marine biotoxins, trace elements, migration from food packaging, food process contaminants, adulteration, authenticity and allergenicity of foods. Papers are published on animal feed where residues and contaminants can give rise to food safety concerns. Contributions cover chemistry, biochemistry and bioavailability of these substances, factors affecting levels during production, processing, packaging and storage; the development of novel foods and processes; exposure and risk assessment.
