Eisenia fetida was used as a model terrestrial organism to assess the potential ecotoxicity of molecular pristine C₆₀ in soil. Reproduction (assessed by counting cocoon numbers) was hindered only at very high C₆₀ concentrations (5% by weight), and C₆₀ (up to 1%) was not avoided and did not hinder earthworm growth. This suggests that E. fetida is unlikely to experience acute toxicity as a result of C₆₀ occurrence in soil. Whether sublethal toxicity may decrease earthworm populations that are chronically exposed to C₆₀ at lower concentrations remains to be determined.
利用赤子爱胜蚓作为模式陆生生物来评估土壤中分子形式的原始 C₆₀ 的潜在生态毒性。只有在非常高的 C₆₀ 浓度（按重量计 5%）下，赤子爱胜蚓的繁殖（通过计算茧数来评估）才会受到阻碍，并且 C₆₀（高达 1%）不会被回避，也不会阻碍蚯蚓的生长。这表明赤子爱胜蚓不太可能因土壤中 C₆₀ 的存在而遭受急性毒性。亚致死毒性是否会降低长期慢性暴露于低浓度 C₆₀ 的蚯蚓种群，仍有待确定。
