在塑料生产过程中使用塑料添加剂来改变聚合物的属性和稳定性。随着海洋塑料废物的降解，这些添加剂可能会浸出，对全球海洋生态系统有害。尽管大量添加剂渗入海洋环境，但人们对其对海洋浮游动物的直接影响知之甚少。在这里，我们在 4 天的连续剂量反应中测试了四种塑料添加剂 UV-327、Irganox 1010、DEHP 和对羟基苯甲酸甲酯（均常用于塑料制造）对紫海胆 (Strongylocentrotus purpuratus) 幼虫生长和存活的影响。至少一剂对羟基苯甲酸甲酯、UV-327 和 Irganox 1010 可使幼虫体长显着缩短约 5%。相比之下，所有化合物都会使幼虫存活率降低 20-70%，且中剂量而非高剂量的效果最强。我们的结果强调，应该测试塑料添加剂对海洋生物的影响。
Plastic additives are utilized during the production of plastic to modify the attributes and stability of the polymer. As oceanic plastic waste degrades, these additives can leach, and are harmful to global marine ecosystems. Despite the high abundance of additives leached into the marine environment, little is known about their direct impact on marine zooplankton. Here we test for impacts of four plastic additives, UV-327, Irganox 1010, DEHP, and methylparaben, all commonly used in plastic manufacturing, on purple sea urchin (Strongylocentrotus purpuratus) larval growth and survival in a serial dose response for 4 days. Methylparaben, UV-327, and Irganox 1010 significantly reduced larval body length by about 5% for at least one dose. In contrast, all compounds reduced larval survival by 20–70% with strongest effects at intermediate rather than high doses. Our results highlight that plastic additives should be tested for their effects on marine organisms.
