Abstract
We investigated the impact of shape (beads, fibers and films) and size (0.5 and 1.0 mm; diameter or length) of polypropylene microplastics (MPs) on MP transport by a springtail species, Folsomia candida in dishes. The percentages of transported beads, fibers and films were 9.10%, 3.18% and 4.10%, respectively. For 1.0 mm MPs, the number of MPs transported was significantly higher for beads than for fibers and films, whereas, for 0.5 mm MPs, the number was significantly higher for fibers than for the other MP types. Additionally, the number of MPs transported was higher for small fibers than for large fibers, whereas it was higher for large beads than for small beads. These results indicate that the effects of F. candida on MP migration depend on MP shape and size. Our results highlight the importance of considering the physical characteristics of MPs while elucidating the interaction between soil fauna and MPs.
我们研究了形状(珠子、纤维和薄膜)和尺寸(0.5和1.0 mm)的影响;直径或长度)的聚丙烯微塑料(MPs)对MP运输的弹尾物种，假丝酵母菌在盘子。运珠率为9.10%，纤维率为3.18%，薄膜率为4.10%。对于1.0 mm MPs，微珠的MPs运输数量明显高于纤维和薄膜，而对于0.5 mm MPs，纤维的MPs运输数量明显高于其他类型的MPs。此外，小纤维的MPs转运数量高于大纤维，而大纤维的MPs转运数量高于小纤维。这些结果表明，念珠菌对MP迁移的影响取决于MP的形状和大小。我们的研究结果强调了在阐明土壤动物与MPs之间的相互作用时考虑MPs物理特性的重要性。
期刊介绍：
Environmental Pollutants & Bioavailability is a peer-reviewed open access forum for insights on the chemical aspects of pollutants in the environment and biota, and their impacts on the uptake of the substances by living organisms.
Topics include the occurrence, distribution, transport, transformation, transfer, fate, and effects of environmental pollutants, as well as their impact on living organisms. Substances of interests include heavy metals, persistent organic pollutants, and emerging contaminants, such as engineered nanomaterials, as well as pharmaceuticals and personal-care products as pollutants.
