Abstract

Fibrous microplastics represent an anthropogenic pollutant affecting aquatic systems globally. However, fibres formed from natural materials (e.g., cotton or wool) have only recently been recognised as potentially posing similar ecological threats as their synthetic counterparts. In this study we employed a laboratory-based aquarium experiment to examine the ingestion of preselected anthropogenic (polyester – microplastic) and ‘natural’ (cotton) microfibres by the Asian Clam (Corbicula fluminea). We considered how the ingestion, retention, and rejection of preselected microfibres (specific, distinctive colours), differed associated with fibre type (cotton vs polyester), biofilm development (control – no biofilm / uncultured, 1-week culturing and 4-week culturing) and time (1-48 hours). We found that the ingestion of microfibres was complex, dependent on the interaction of culturing and fibre type. Greater retention of synthetic microfibres was recorded compared to ‘natural’ microfibres as the duration of culturing increased. We also observed that ingestion of microfibres was immediate but that microfibres were rejected and visually observed in pseudofaeces. Our results suggest that the time microfibres spend within the environment, allowing biofilm to develop on their surface, influences the ingestion of microfibres and we call for further studies to consider this in the future.

纤维状微塑料是影响全球水生系统的人为污染物。然而，由天然材料（如棉花或羊毛）形成的纤维最近才被认为可能会对生态环境造成与其合成材料类似的威胁。在这项研究中，我们利用实验室水族箱实验来研究亚洲蛤蜊（Corbicula fluminea）摄取预选的人为（聚酯--微塑料）和 "天然"（棉花）微纤维的情况。我们研究了预选微纤维（特定、独特的颜色）的摄取、保留和排斥与纤维类型（棉与聚酯）、生物膜发展（对照-无生物膜/未培养、培养 1 周和培养 4 周）和时间（1-48 小时）的关系。我们发现，微纤维的摄取是复杂的，取决于培养和纤维类型的相互作用。与 "天然 "超细纤维相比，随着培养时间的延长，合成超细纤维的保留率更高。我们还观察到，微纤维的摄取是即时的，但微纤维会被排出并在假粪便中被肉眼观察到。我们的研究结果表明，超细纤维在环境中停留的时间（允许生物膜在其表面形成）会影响超细纤维的摄取，我们呼吁今后开展进一步的研究来考虑这个问题。

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
