橡胶生产中普遍使用抗氧化剂，以改善橡胶性能，延缓老化，延长使用寿命。然而，近年来的研究表明，橡胶抗氧化剂及其转化产物会对环境生物产生不良影响，甚至引发环境事件，这引起了人们对橡胶抗氧化剂及其转化产物的环境发生和潜在影响的极大关注。本文综述了国内外橡胶抗氧化剂的种类及应用，阐述了橡胶抗氧化剂在环境中的形成机理，重点介绍了橡胶抗氧化剂对臭氧氧化降解的影响。本文进一步综述了抗氧化剂及其TPs的潜在毒性作用，以提高对其生物健康影响和环境风险的认识。最后，总结了抗氧化剂及其tp在环境中的分布情况，并结合近年来的研究成果阐述了它们对环境的影响。由于目前对这些化合物的毒性和生物效应的认识有限，为了更好地评估这些抗氧化剂的各种TPs及其对环境的影响，需要进一步的研究。据我们所知，这是第一次对抗氧化剂及其在环境中的TPs进行综述，这可能在不久的将来提高橡胶制品及其TPs的环境风险意识。
Antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. However, recent studies have revealed that their transformation products (TPs) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber antioxidants and their TPs. In this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their TPs in the environment, emphasizing their influence on the ozone oxidative degradation. The potential toxic effects of antioxidants and their TPs are further reviewed to improve understanding of their biological health impact and environmental risks. Finally, the environmental occurrences of antioxidants and their TPs are summarized and their environmental impacts are demonstrated based on the recent studies. Due to the currently limited understanding on the toxic and biological effects of these compounds, further studies are required in order to better assess various TPs of these antioxidants and their environmental impact. To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
