生物基微塑料对蚯蚓的生物效应
Biological effects of bio-based microplastics on earthworms
摘要
Abstract
With the development and application of bio-based plastics,the biological effects of bio-based microplastics(MPs)in the soil environment have attracted more and more attention and concern in related fields.Using earthworms as test subjects,the biological effects of four bio-based MPs(polybutylene succinate(PBS),polybutylene adipate terephthalate(PBAT),polyethylene 2,5-furandicarboxylate(PEF)and polylactic acid(PLA))on earthworms are investigated and compared with petroleum-based MPs(polyethylene terephthalate(PET)).The results show that bio-based MPs inhibit the growth of earthworms and induce oxidative stress and lipid peroxidation.At the same time,bio-based MPs can inhibit the activity of earthworm neurotransmitters and cause damage to the nervous system.The biological effects of MPs on earthworms are closely related to the species,concentration and exposure time of MPs.There are significant differences in the effects of different types of MPs on earthworm biological indicators,and the effects of bio-based MPs are generally greater than those of petroleum-based MPs.However,the results of integrated biomarker response index evaluation show that there is no significant difference in the biological effects of bio-based MPs and petroleum-based MPs on earthworms.The results of the study provide a research basis to explore the biological effects of MPs from different sources(bio-based or petroleum-based)and basic data for the environmental risk assessment of bio-based MPs.关键词
