Abstract

Herbicide residue levels were analyzed in agricultural soils of Batak plain and health risk assessments were made for relevant pesticides. Herbicide contamination levels were analyzed with the use of Quick-Easy-Cheap-Efficient-Rugged-Safe (QuEChERS)-liquid chromatography/tandem mass spectrometry (LC-MS/MS) procedure. Herbicide-free soil samples were spiked at two different levels. Overall recovery of the method was 87.32%. Present findings were parallel to SANTE recovery limits. About 50% of collected samples from the study sites contained herbicides at different concentrations. Totally, eight herbicides were detected, and herbicide concentrations ranged between 1.085 and 1724.23 μg kg-1. Metolachlor had the highest concentration (1724.23 μg kg-1) in a sample taken close to the pesticide waste disposal area. Six herbicides were detected at different concentrations in the same sample. Persistent herbicides (terbuthylazine and pendimethalin) were detected in 35 samples. Risk assessments revealed that hazard index (HI) and hazard quotient (HQ) were less than 1. The greatest HQ values were identified for terbuthylazine as 2772.48 × 10-7 and 20793.61 × 10-7 for adults and children, respectively. The HI for all herbicides were 3916.05 × 10-7 for adult and 29370.39 × 10-7 for children.

巴塔克平原农业土壤的除草剂污染与风险评估。
对巴达克平原农业土壤中的除草剂残留水平进行了分析,并对相关农药进行了健康风险评估。采用快速、简便、高效、可靠、安全(QuEChERS)-液相色谱/串联质谱(LC-MS/MS)程序对除草剂污染水平进行了分析。对不含除草剂的土壤样品进行了两种不同水平的添加。该方法的总体回收率为 87.32%。目前的研究结果与 SANTE 回收率限值相当。在研究地点采集的样本中,约 50%含有不同浓度的除草剂。总共检测到八种除草剂,除草剂浓度介于 1.085 至 1724.23 μg kg-1 之间。在靠近农药废物处理区的一个样本中,甲草胺的浓度最高(1724.23 微克/千克-1)。在同一样本中检测到六种不同浓度的除草剂。在 35 个样本中检测到持久性除草剂(特丁基嗪和戊唑醇)。风险评估结果显示,危害指数(HI)和危害商数(HQ)均小于 1。所有除草剂的 HI 值成人为 3916.05 × 10-7 ,儿童为 29370.39 × 10-7。
