摘要

目的:评估三嗪类除草剂污染土壤和地下水的风险,以减少乌克兰和欧盟人为环境污染并减少对公共健康的潜在负面影响。材料和方法:考虑到乌克兰和欧盟的气候条件,含有5种三嗪类活性物质的14种制剂及其在土壤和水中的环境命运。现场卫生实验方法、气液色谱法、分析和统计方法、卫生建模,采用实验浸出指数(ELI)、(GUS)、(RLPI)、(LIX)、(DT50)和(KOC)、SCI-GROW、LEACHmod。结果:对所研究物质的理化性质分析表明,根据迁移能力将其分为可迁移性和中等迁移性。所研究物质的计算T50使我们能够确定它们的危害等级。物质属于2-3类(丙氰菊酯和特丁拉西嗪- 2类,中等持久性(30-100天),甲基三苯脲、甲基硫苯磺隆和甲霉嗪-3类,弱持久性(少于30天))。测定系数(R2)范围为0.704 ~ 0.995。结论:根据GUS,除甲基硫虫隆外,大部分研究物质均有中等程度的渗入地下水的可能性。而在欧盟土壤中,除臭虫菊酯的指数很低,甲基三苯菊酯的指数很低,特丁基嗪和甲氰菊酯的指数中等,甲基噻吩磺隆的指数很高。SCI-GROW评估显示,乌克兰大部分农药的用量明显低于国际标准(除除臭菊酯外),这可以解释为乌克兰和欧盟土壤中最大施用量、处理次数存在显著差异,在某些情况下,乌克兰和欧盟土壤中物质的抗性存在差异。

Comparative assessment of the risks of soil and groundwater pollution by triazine herbicides in Ukraine and European Union countries.

Objective: Aim: Assessment of the risk of soil and groundwater contamination by triazine herbicides to reduce anthropogenic environment pollution and decrease the potential negative impact on public health in Ukraine and the EU.

Patients and methods: Materials and Methods: 14 preparations containing 5 active substances of the triazine class and its environmental fate in soil and water considering Ukraine and EU climatic conditions. Methods of in-field hygienic experiment, gas-liquid chromatography, analytical and statistical methods, hygienic modelling using Experimental Leaching Index (ELI), (GUS), (RLPI), (LIX), (DT50) and (KOC), SCI-GROW, LEACHmod.

Results: Results: Analysis of the physicochemical properties of studied substances showed that they were classified as mobile or moderately mobile by migration ability. Calculated T50 for studied substances allowed us to determine the hazard classes for them. Substances pertain to 2-3 classes (promethrin and terbuthylazine - class 2, moderately persistent (30-100 days), tribenuron-methyl, thifensulfuron-methyl and metribuzin - class 3, weak persistency (less than 30 days)). The determination coefficient (R2) values ranged from 0.704 to 0.995.

Conclusion: Conclusions: According to the GUS, most of the studied substances have a moderate possibility of leaching into groundwater, except for thifensulfuron-methyl. While in EU soils the index for promethrin is very low, tribenuron-methyl is low, terbuthylazine and metribuzin are moderate, and thifensulfuron-methyl is high. The SCI-GROW assessment showed that most of them have significantly lower values in Ukraine than international values (except for promethrin), which can be explained by significant dissimilarities in maximum application rates, number of treatments, and in some cases - different resistance of substances in Ukrainian and EU soils.
