| Résumé : |
Earthworms were grown in soils to which various tannery byproducts containing chromium were added. The tannery byproducts and the chromium (Cr) contents of the experimental soil mixtures after they were added were as follows : blue shavings 670 ppm, tannery sludge 1,835 ppm, leather buffings 970 ppm. The Cr content of the original control soil was 16 ppm.
Incorporating the shavings into the soil had no effect on the population of worms, although it did increase the Cr content of the worms and their casts. The tannery sludge decreased the worm population and the leather buffings decreased the size of the worms produced. However, the worms survived in all of these experimental soils and evidently ate the chromium containing materials, since their gut contained 100 ppm or more of Cr. |
