We examined the bioaccumulation of essential (Cu, Fe, Se, and Zn) and nonessential (As and Hg) trace elements in 2 aquatic invertebrate species (adult snails and mayfly nymphs) with different feeding habits at the site of a coal ash spill. Differences in food web pathway, exposure concentrations, and biological processing affected bioaccumulation patterns in these species. Mayflies had higher body burdens, but snails had higher retention of most elements studied. Environ Toxicol Chem 2020;39:2437–2449. © 2020 SETAC

在粉煤灰污染地点比较蜗牛和May蝇中的微量元素生物富集和净化。

我们在粉煤灰溢漏现场检查了2种水生无脊椎动物物种（成年蜗牛和may蝇若虫）中必需（铜，铁，硒和锌）和非必需（砷和汞）微量元素的生物蓄积性。食物网途径，接触浓度和生物加工的差异影响了这些物种的生物积累模式。f蝇具有较高的身体负担，但是蜗牛对大多数研究元素的保留较高。2020年《环境毒理学》； 39：2437-2449。©2020 SETAC
