    摘要:

    土壤是人类赖以生存和发展的主要自然资源,近年来,轮胎橡胶防老剂N-(1,3-二甲基丁基)-N’-苯基对苯二胺(6PPD)及其臭氧化产物N-(1,3-二甲基丁基)-N’-苯基对苯醌(6PPD-Q)的水生生物风险引发全球关注,但对其土壤环境行为和土壤生物区系影响还知之甚少。研究表明,土壤是轮胎磨损颗粒(TWPs)的一个重要的“汇”。对苯二胺类(PPDs)橡胶防老剂性能优良,应用非常广泛,能够随着TWPs进入环境介质中然后被释放出来,并产生PPD-Qs等衍生物。因此研究PPDs类化合物及其衍生物PPD-Qs在土壤中的归趋和生态环境风险具有重要的意义。本文聚焦于土壤环境安全和生态健康,陈述了6PPD及6PPD-Q在土壤环境中赋存、迁移、转化等行为特征,介绍了6PPD及6PPD-Q在土壤生物中的累积、转运和代谢机制,并阐述其对土壤生物的毒性效应和致毒机制,为6PPD及6PPD-Q污染的生态风险评估和防控提供理论基础。

    Abstract:

    Soil is the main natural resource for human survival and development. In recent years, the aquatic risks of tire rubber antioxidant N-(1, 3-dimethylbutyl-N""-phenyl-p-phenylenediamine (6PPD) and its ozonated product N-(1, 3-dimethylbutyl-N"" -phenyl-p-benzoquinone (6PPD-Q) have attracted global attention, but little is known about their soil environmental behavior and soil biota effects. Research has shown that soil is an important "aggregation" of tire wear particles, and the TWPs entering the environment release various of additives, such as rubber antioxidants, silica, metals, etc. Among them, p-Phenylenediamines(PPDs) are the most widely added rubber antioxidants due to their excellent performance, which can be released as TWPs entered environmental media and produced derivatives such as PPD-Qs. Therefore, studying the fate and ecological environmental risks of 6PPDs and their derivatives in soil is of great significance. This article focuses on soil environmental safety and ecological health, stating the behavioral characteristics of the occurrence, migration, and transformation of 6PPD and 6PPD-Q in the soil environment. For providing a theoretical basis of the ecological risk assessment and prevention and control of 6PPD and 6PPD-Q pollution, this paper introduces the accumulation, transportation, and metabolic mechanisms of 6PPD and 6PPD-Q in soil organisms, and elaborates on their toxic effects and mechanisms on soil organisms.
