This study investigated the degradation characteristics and conducted a risk assessment of four pesticides (Diniconazole, Dinotefuran, Metconazole, and Tebuconazole) in the leaves and roots of radish. Radish was cultivated in two greenhouse fields, and samples were collected at 0, 1, 2, 3, 5, 7, and 10 days after pesticide application. Sample analysis was performed using LC-MS/MS, and the recovery rates ranged from 70.1% to 118.6%. The biological half-life of Diniconazole was found to be 6.2 days (leaf and root), Dinotefuran was 5.3 days (leaf) and 4.6 days (root), Metconazole was 9.3 days (leaf) and 3.2 days (root), and Tebuconazole was 8.0 days (leaf) and 5.1 days (root). After comparing the maximum residue limits (MRL) of each pesticide in Korea with the residues during the pre-harvest interval (PHI), Diniconazole showed a Hazard quotient (HQ) exceeding 1, indicating potential risks for true consumers. Furthermore, Tebuconazole showed an HQ of 0.3 or higher, indicating a significant level of risk.
本研究调查了四种农药（烯唑醇、呋虫胺、戊唑醇和戊唑醇）在萝卜叶片和根部的降解特性，并进行了风险评估。萝卜在两个温室田地中种植，在施用农药后的0、1、2、3、5、7和10天采集样本。使用LC-MS/MS进行样本分析，回收率在70.1%至118.6%之间。发现烯唑醇的生物半衰期为6.2天（叶片和根部），呋虫胺为5.3天（叶片）和4.6天（根部），戊唑醇为9.3天（叶片）和3.2天（根部），戊唑醇为8.0天（叶片）和5.1天（根部）。将韩国每种农药的最大残留限量（MRL）与收获前间隔期（PHI）内的残留量进行比较后，烯唑醇的危害商数（HQ）超过1，表明对实际消费者存在潜在风险。此外，戊唑醇的HQ为0.3或更高，表明存在显著风险水平。
