Avoidance of brass powder‐contaminated soil by the earthworm,lumbricus terrestris

摘要

AbstractTests of the avoidance of brass powder (70 Cu, 30 Zn) contaminated soils by the earthwormLumbricus terrestrisat concentrations ranging from 0 to 200 μg/g were conducted. Avoidance was significant (p<0.001) at brass concentrations as low as 38 μg/g. Avoidance was found to be a more sensitive indicator of the impact of brass powder on the worms than sublethal effects measured by weight los
