Abstract

The occurrence of pesticide residues, their metabolites and degradation products in 49 edible mushrooms (fresh, dried, canned and frozen) was investigated. Using QuEChERS extraction, followed by liquid and gas chromatography coupled with tandem mass spectrometry, the samples collected from Czech markets were tested for 427 analytes. A total of 21 pesticide residues, their metabolites and pesticide synergists were found in quantifiable concentrations. The most frequently detected pesticide residues included prochloraz and its metabolites, metrafenone and carbendazim. Two mushroom samples were found to be in violation of the maximum residue level. In addition, the fate of 13 pesticides during the processing of fresh mushrooms was investigated. The processing factors calculated from the data ranged from 6.0 to 12.3 for drying and from 0.3 to 1.3 for deep-freezing. The results showed that most of the pesticide residues tested were stable under the conditions of mushroom processing.

捷克市场新鲜和加工食用蘑菇中的农药残留。

对49种食用菌（鲜蘑菇、干蘑菇、罐头蘑菇和冷冻蘑菇）的农药残留及其代谢产物和降解产物进行了调查。使用QuEChERS提取，然后用液相色谱和气相色谱-串联质谱法，对从捷克市场收集的样品进行427种分析物的测试。共发现21种农药残留、其代谢物和农药增效剂，其浓度可量化。最常检测到的农药残留包括咪鲜胺及其代谢产物、甲基苯酮和多菌灵。两个蘑菇样品被发现违反了最高残留水平。此外，还调查了13种农药在鲜蘑菇加工过程中的去向。根据数据计算出的干燥处理系数在6.0至12.3之间，深度冷冻处理系数在0.3至1.3之间。结果表明，在蘑菇加工条件下，大部分农药残留是稳定的。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
