Summary: | Nanotechnology is playing an increasing role in the society, but very little is known about the environmental toxicity of nanotechnological products. Few previous studies have been published with regard to the effect of nanoparticles on soil organisms. The present paper deals with the toxicity of carbon double-walled nanotubes (DWNT) and C60 fullerenes to the soil-dwelling earthworm
Eisenia veneta, with the aim of evaluating the lethal and sub-lethal toxicity. Reproduction of
E. veneta was affected by DWNT administered through food at concentrations above 37
mg
DWNT/kg food. The most sensitive toxicological parameter was reproduction (cocoon production), with no effect on hatchability, survival or mortality at up to 495
mg
DWNT/kg and 1000
mg
C60/kg. |
