摘　　要：微塑料作为一种新兴污染物,其污染已成为全球广泛关注的热点环境问题。特别是农田土壤中微塑料污染对食物链和陆生生态系统构成了潜在威胁,微塑料及其与其他污染物的混合作用对蚯蚓造成了一系列不利影响,包括体重减轻、运动能力下降、生存率降低和免疫力减弱等。此外,微塑料与污染物的混合暴露干扰了蚯蚓的肠道微生物平衡,引发其细胞水平上的氧化应激和DNA损伤。该文从研究对象、试验设计、微塑料及混合污染物的类型和浓度等方面综述了关于微塑料及混合污染物对蚯蚓生长和生理影响的研究进展。同时,提出了未来研究需进一步标准化研究方法以增强结果的可比性,加强田间条件下对微塑料污染的系统评估,关注微塑料对蚯蚓的长期影响,以期为环境保护和土壤污染治理提供参考依据。Microplastics(MPs),as an emerging pollutant,is one of hot environmental issues and receives global concerns.The pollution of MPs in farmland soil poses potential threats to the food chain and terrestrial ecosystems.MPs and mixed pollutant with other pollutants have caused a range of negative impacts on earthworms,such as weight loss,reduced mobility,lower survival rates,and weakened immunity.Moreover,the mixed exposure to MPs and other pollutants disrupt the balance of intestinal microorganisms in earthworms,leading to oxidative stress and DNA damage at the cellular level.This study summarizes the effects of single pollutant MPs and mixed pollution with heavy metals and organic pollutants on the growth and physiology of earthworms,in terms of the study subjects,experimental design,and the types and concentrations of pollutants.This review highlights the need in standardizing research methods to enhance the comparability of results from different studies,strengthening systematic assessment under field conditions,and paying attention to the long-term effects of MPs on earthworms,so as to provide a scientific basis for environmental protection and soil pollution management.
