TROPHOMETABOLIC POTENTIAL OF ESENIA FETIDA SAVIGNY, 1826 (OLIGOCHATA, LUMBRICIDAE) CAUSED BY COPPER NANOPARTICLES AND COPPER OXIDE IN THE SOIL

Depending on the concentrations of Cu and CuO nanoparticles (NPs) (50, 100 and 500 mg/kg dry matter) introduced into an artificial soil, the influence of Cu NPs upon E. fetida is much stronger than similar CuO doses. In particular, this was reflected in higher mortality (80%) and a 50% weight reduction of the worm (p ≤ 0.05) when the dose of Cu NPs was 500 mg/kg, whereas the validity limit of the test (20%) was not exceeded with a similar dose of CuO.
