Abstract Plastic is one of the major sources of pollution in modern oceans. When in seawater, toxic plasticizers (the additives incorporated in plastic polymers during manufacturing processes) typically diffuse and accumulate in sediments and in benthic and pelagic organisms' tissues. These plastic leachates affect survival, behavior and metabolism of various marine metazoans, but little effort was placed in studying their effect on protists. In this contribution we monitored the short-term effect of polypropylene (PP) leachates at both environmentally realistic and chronic concentrations on Haynesina germanica locomotion and metabolism. We found that PP leachates has no lethal nor effects on this species activity. Taken together, these results suggest that benthic foraminifera may be more resistant than marine metazoans to plasticizers pollutants.

底栖有孔虫 Haynesina Germanica 对微塑料渗滤液的运动行为和代谢反应

摘要 塑料是现代海洋污染的主要来源之一。在海水中时，有毒增塑剂（在制造过程中加入塑料聚合物中的添加剂）通常会在沉积物以及底栖和远洋生物组织中扩散和积聚。这些塑料渗滤液影响各种海洋后生动物的生存、行为和新陈代谢，但很少有人研究它们对原生生物的影响。在这项贡献中，我们监测了聚丙烯 (PP) 浸出液在环境现实和长期浓度下对德国海尼丝藻运动和代谢的短期影响。我们发现 PP 渗滤液对该物种的活动没有致命的影响。综合起来，
