Résumé : |
Greenhouse trials were carried out to grow crops in soil to which chromium III in various forms had been added. The dressings included tannery sludges from both bovine and sheepskin production, a proprietary fertilizer manufactured from chrome leather scrzp, a sewage-plant sludge containing appreciable amounts of Cr III, and precipitated Cr III hydroxide. The progress of the various crops was minotored and their fruit, leaves, roots, etc., were analysed for Cr III, as applicable. Although some of the mixtures were beneficial to plant growth, these effects could not be attributed to the presence of Cr III, but the results fully confirmed the nontoxicity of Cr III, at least at a level of 500 mg/kg in the soil. The concentration of Cr III in the soil had a negligible effect on the uptake of Cr III by the edible portions of the crops. |
