摘要: A mayfly, Ephemerella grandis, and a stonefly, Pteronarcys californica, were exposed to lead, zinc, copper, silver determine the acute metal toxicities. The insects tested found be more tolerant of heavy metals than most fish. They concentrated in relative proportion occurrence stream by some predictable, reproducible factor. These data, together with field tests, indicate aquatic may serve as effective biological monitors pollution where fish-kills are involved.
