In laboratory studies, microplastics and/or nanoplastics (MPs/NPs) have been shown to cause a variety of ecotoxicological effects on soil invertebrates. Existing data on the effects of these plastic debris on biological functions and physiological systems, showed a great variability among studies. Thus, how soil invertebrates respond to different types, shapes, sizes and concentrations of pristine MPs/NPs remains to be further characterized. The present work is an up-to-date review on quantitative and qualitative data on the effects of pristine MPs/NPs on soil invertebrates in laboratory conditions. Research priorities are also discussed. Out of a total of 1061 biological endpoints investigated in 56 studies, 49% were significantly affected after exposed to pristine MPs/NPs. The polymers with chloro and phenyl groups had more negative impacts on soil invertebrates than other polymers. Most studies used earthworm and nematode species as model organisms. For nematodes, the impact of MPs/NPs seemed to be concentration-dependent and higher concentrations of pristine MPs/NPs appeared to have more adverse impacts on biological functions and physiological systems, but this trend was not confirmed in earthworms. Meta-analysis revealed that pristine MP/NP concentrations higher than 1 g kg⁻¹ (in soil) may decrease growth and survival of earthworms, while a concentration higher than 1 μg L⁻¹ (in water) may affect nematode reproductive fitness.

在实验室研究中，微塑料和/或纳米塑料（MPs / NPs）已显示对土壤无脊椎动物产生多种生态毒理作用。这些塑料碎片对生物学功能和生理系统影响的现有数据显示，研究之间存在很大差异。因此，土壤无脊椎动物如何响应原始MPs / NPs的不同类型，形状，大小和浓度还有待进一步表征。本工作是对原始MPs / NPs在实验室条件下对土壤无脊椎动物影响的定量和定性数据的最新综述。还讨论了研究重点。在56个研究中调查的1061个生物学终点中，有49％在暴露于原始MPs / NPs后受到了显着影响。具有氯和苯基的聚合物比其他聚合物对土壤无脊椎动物的负面影响更大。大多数研究使用worm和线虫作为模型生物。对于线虫而言，MPs / NPs的影响似乎是浓度依赖性的，而更高浓度的原始MPs / NPs似乎对生物学功能和生理系统具有更大的不利影响，但这种趋势在earth中并未得到证实。荟萃分析显示原始MP / NP浓度高于1 g kg 但是this并没有证实这种趋势。荟萃分析显示原始MP / NP浓度高于1 g kg 但是this并没有证实这种趋势。荟萃分析显示原始MP / NP浓度高于1 g kg^-1（在土壤中）可能会降低decrease的生长和存活，而浓度高于1μgL ^-1（在水中）可能会影响线虫的繁殖能力。
