Abstract

Picoxystrobin is a systemic fungicide widely used on potato, citrus fruit, and Dendrobium officinale. To provide information for the risk assessment of potato, citrus, and Dendrobium officinale, field experiments combined with QuEChERS and HPLC-MS/MS were performed to detect picoxystrobin. Picoxystrobin had good linearity (R2 > 0.99), the average recovery rate was 75 - 102%, and the relative standard deviation was 1 - 11%. Picoxystrobin was utilized as the test agent in field experiments, and samples were evaluated and analyzed at various times after the final application utilizing random sampling. The results showed that picoxystrobin residuals in potato and citrus (orange meat) were ˂ 0.01 mg kg-1, whereas those in citrus whole fruit, D. officinale (fresh), and D. officinale (dried) were < 0.05 - 0.084, 0.16 - 3.82, and 0.34 - 9.05 mg kg-1, respectively. Based on these results, both the acute risk quotient (2.77%) and chronic risk quotient (8.7%) were ˂100%, and the dietary risk assessment indicated that the intake of picoxystrobin residues in potato, citrus fruit, and D. officinale did not pose a health risk. This study can guide the reasonable use of picoxystrobin in potato, citrus fruit, and D. officinale.

马铃薯(Solanum tuberosum)、柑橘(Citrus reticulata Blanco)和铁皮石斛中吡蚜酮的残留分析和膳食风险评估 Kimura et Migo.
啶氧菌酯是一种广泛用于马铃薯、柑橘类水果和铁皮石斛的系统杀菌剂。为了给马铃薯、柑橘和铁皮石斛的风险评估提供信息,我们结合 QuEChERS 和 HPLC-MS/MS 进行了田间试验,以检测啶氧菌酯。啶氧菌酯具有良好的线性关系(R2 > 0.99),平均回收率为 75 - 102%,相对标准偏差为 1 - 11%。在田间试验中使用啶氧菌酯作为试验药剂,并在最终施药后的不同时间通过随机取样对样品进行评估和分析。结果表明,马铃薯和柑橘(橘肉)中的啶氧菌酯残留量˂ 0.01 mg kg-1,而柑橘全果、D. officinale(鲜)和 D. officinale(干)中的啶氧菌酯残留量分别小于 0.05 - 0.084、0.16 - 3.82 和 0.34 - 9.05 mg kg-1。根据上述结果,急性风险商数(2.77%)和慢性风险商数(8.7%)均为˂100%,膳食风险评估结果表明马铃薯、柑橘类水果和欧当归中的吡唑醚菌酯残留摄入量不会对健康造成危害。这项研究可指导在马铃薯、柑橘类水果和当归中合理使用吡唑醚菌酯。
