Abstract

Microplastics merit attention as they can be ingested by lower trophic organisms, transferred to the food web, and pose potential risks to higher trophic levels. This study investigated the accumulation and effects of polyethylene microbeads (PEMBs, 63-75 μm) on adult water flea Moina macrocopa (600-800 μm), an order-magnitude difference in size, as a result of acute exposure. The organisms were exposed to PEMBs in four treatments of 0 (the Control), 5, 50, and 500 mg PEMB/L for examining PEMB accumulation, survival and reproduction of the organisms after the 24- and 48-h exposures. In general, M. macrocopa ingested PEMBs within 24-h exposure and reached the cumulative PEMB accumulation value of 0.17 ± 0.21 beads/adult after 48-h exposure in the 500 mg PEMB/L treatment. Exposure to PEMBs resulted in a statistically significant decrease of the cumulative survival rates, from 93 ± 12% in the Control to 37 ± 21% in the 500 mg/L treatment. Nevertheless, exposure to PEMBs did not significantly reduce the cumulative reproduction (p > 0.05), although a decrease was observed. This study suggests that the relatively large-size PEMBs could be ingested by the relatively small-size M. macrocopa and pose potential risks to these organisms.

急性接触聚乙烯微珠及其对水蚤 Moina Macrocopa 的影响。
微塑料可被低营养级生物摄入,转移到食物网中,并对高营养级生物构成潜在风险,因此值得关注。本研究调查了急性接触聚乙烯微珠(PEMBs,63-75 μm)对成年水蚤Moina macrocopa(600-800 μm)的积累和影响,两者大小相差一个数量级。生物在 0(对照组)、5、50 和 500 毫克 PEMB/L 四种处理中暴露于 PEMB,以检测暴露 24 和 48 小时后 PEMB 的积累、生物的存活和繁殖情况。一般来说,大鳞栉水母在接触 PEMB 24 小时内摄入 PEMB,在接触 500 毫克 PEMB/L 处理 48 小时后,PEMB 累积值达到 0.17 ± 0.21 珠/成体。接触 PEMB 后,累积存活率从对照组的 93 ± 12% 降至 500 毫克/升处理组的 37 ± 21%,差异有统计学意义。尽管如此,暴露于 PEMBs 并未显著降低累积繁殖率(p > 0.05)。这项研究表明,体型相对较小的大菱鲆可能会摄入相对较大的 PEMB,从而对这些生物造成潜在风险。
