摘要:

为掌握浙江滩涂养殖质量安全状况,建立了一套分散固相萃取结合超高效液相色谱质谱联用法同步测定有机磷类、拟除虫菊酯类和大环内酯类共16种农药残留的检测方法,该法同时适用于水产品及其养殖环境。样品采用2%乙酸酸化乙腈溶液提取,提取液、QuEChERS萃取盐包、QuEChERS净化管净化后上机分析。应用该法筛查了2024—2025年浙南典型养殖区滩涂贝类及其养殖环境中16种农药的残留水平,并对其中检出的农药进行膳食暴露风险评估。结果表明:建立的检测方法对16种农药在1~50 ng·mL-1范围内线性关系良好,决定系数(R2)均大于0.995;在4个添加水平(4、10、20、50 μg·kg-1)下的回收率为65.21%~120.00%,相对标准偏差为0.24%~11.17%。建立的检测方法对三唑磷的定量限在生物体中为0.1 μg·kg-1,在沉积物和水样中分别为0.5 μg·kg-1和0.5 μg·L-1;对其他15种目标物的定量限在生物体中为0.2~4.0 μg·kg-1,在沉积物和水样中分别为0.8~10.0 μg·kg-1和0.8~10.0 μg·L-1。用建立的方法从检测的贝类样品中检出三唑磷、甲氰菊酯2种农药残留,从沉积物中检出三唑磷残留,但未从水样中检出农药残留。检出的两种农药的慢性膳食风险为0.007%~0.578%,急性膳食风险为0.845%~51.798%,均低于100%,风险处于可接受范围。

Abstract:

To clarify the quality and safety status of coastal mudflat mariculture in Zhejiang Province of China, a sensitive analytical method was established for the simultaneous determination of 16 pesticide residues (including organophosphorus, pyrethroid, and macrolide pesticides) in aquatic products and their mariculture environment using dispersive solid-phase extraction coupled with ultra-high performance liquid chromatography-tandem mass spectrometry. Samples were extracted with 2% acetic acid in acetonitrile, and the extracts were purified using QuEChERS extraction salt packets and QuEChERS cleanup tubes prior to instrumental analysis. This method was applied to determine the residual levels of the 16 target pesticides in mudflat shellfish and their mariculture environment from typical mariculture areas in southern Zhejiang during 2024-2025, and a dietary exposure risk assessment was conducted for the detected pesticides. It was shown that the established method exhibited good linearity for all 16 pesticides in the concentration range of 1-50 ng·mL-1, with coefficients of determination (R2) all exceeding 0.995. The recoveries at four spiked levels (4, 10, 20, and 50 μg·kg-1) ranged from 65.21% to 120.00%, with relative standard deviations (RSDs) of 0.24%-11.17%. The limit of quantification (LOQ) of triazophos was 0.1 μg·kg-1 in biological samples, 0.5 μg·kg-1 in sediment samples, and 0.5 μg·L-1 in water samples; for the other 15 target pesticides, the LOQs were 0.2-4.0 μg·kg-1 in biological samples, 0.8-10.0 μg·kg-1 in sediment samples, and 0.8-10.0 μg·L-1 in water samples. By using the established method, triazophos and fenpropathrin residues were detected in shellfish samples, and triazophos residue was detected in sediment samples, while no pesticide residues were found in water samples. The chronic dietary risk of the two detected pesticides ranged from 0.007% to 0.578%, and the acute dietary risk ranged from 0.845% to 51.798%, all below 100%, indicating that the dietary exposure risks were within an acceptable range.
