2014-6-27 Stream water immediately down gradient from the mined site had 2 µg L-1 Cr, with 1µg L-1 Cr(VI). As chromite is poorly soluble, the water- extractable fraction of Cr is likely the effect of pore-scale redox processes rather than an outcome of bulk concentration. The watershed-scale effects of mining

2018-7-6 Chromium has long been recognized as a toxic, mutagenic and carcinogenic metal. It is toxic to microorganism, plants, animals and humans. Chromium exists in environment in two stable forms: Cr(VI) and Cr(III). Cr(III) is less toxic and insoluble, while Cr(VI) is extremely toxic and highly soluble. Chromium is used in many industrial applications, but it poses a threat to local environment.
