Chromium oxide nanoparticles (NPs) were rapidly synthesized by reduction of potassium dichromate solution with Arachis hypogaea leaf extract containing reducing sugars which act as reducing agent. The results indicated that the aldehyde groups present in the plant extract played an important role in the formation of Cr2O3 nanoparticles. The purification process of the Cr2O3 product does not req...

The effects of thiol compounds (L-cysteine ethyl ester, 2,3-dimercaptosuccinic acid, or 2,3-dimercapto-1-propanesulfonic acid) on the toxicity induced by chromate (potassium dichromate) were investigated in HeLa cells and mice. Chromate-induced cytotoxicity evaluated by inhibition of cell growth and chromium content of the cells was diminished by all of the thiol compounds tested when the cells...

Soil organic carbon (SOC) is an important property in regard to soil and environmental quality. There are many methods determine SOC. In this study, Walkley Black Loss on Ignition were chosen sixty sub-samples representing collected from three different parts of Arsi zone areas Ethiopia, then nine a composite samples used for SOC determination methods. The variables equipment, accuracy, efficie...
