Inhibition effect of glyphosate on the acute and subacute toxicity of cadmium to earthwom Eisenia fetida

0
The acute and subacute toxicities of Cd to earthworm Eisenia fetida (E.fetida) in the presence and absence of glyphosate (GPS) were studied. Cd is highly toxic to E. fetida, while the presence of GPS markedly reduced the acute toxicity of Cd to earthworm, as both the mortality rate of the earthworms and the accumulation of Cd decreased with the increase of GPS/Cd molar ratio. The subcellular distribution of Cd in E. fetida tissues showed that the internal Cd were dominant in the intact cells and fraction heat‐stable proteins fraction. The presence of GPS reduced the concentration of Cd in all fractions, especially the intact cells. During longer period of exposure, the weight loss of earthworm and the total Cd absorption was alleviated obviously by GPS. Therefore, the herbicide glyphosate can reduce the toxicity and bioavailability of Cd in the soil ecosystems at both short‐ and long‐term exposures. Environ Toxicol Chem © 2014 SETAC
