- Solubility: In an experiment performed under inert gas atmosphere, the solubility /in water/ of freshly precipitated chromium(III) hydroxide was determined from under-saturation and from over-saturation at different pH. As an amphoteric hydroxide, the solubility curve of chromium(III) hydroxide is parabolic, depending on pH. The solubility is as follows: >pH 4: moderately soluble; pH 6.8 - 11.5: insoluble; > pH 11.5 - 14 slightly soluble ... at pH 4, the solubility was about 520 mg/L; at pH 6.8 to 11.8, the solubility was about 0.005 mg/L Source: Hazardous Substances Data Bank (HSDB)

- Health Effects: Chromium in its trivalent state is not very toxic. It may be oxidized to hexavalent chromium, a known carcinogen. Hexavalent chromium has also been shown to affect reproduction and development. (A12) Source: Toxin and Toxin Target Database (T3DB)
- Toxicity Summary: IDENTIFICATION AND USE: Chromium trihydroxide (chromic acid) is a green, gelatinous precipitate. It is used as pigment, e.g. Guignet's green; in tanning industry; as a mordant, and as catalyst for organic reactions. HUMAN EXPOSURE AND TOXICITY: Fatal case was described involving 35-year-old woman who developed severe acidosis, massive gastrointestinal hemorrhage, acute renal failure, and hepatic injury following ingestion of chromic acid (50 mL) and died 12 hours after ingestion. Postmortem liver biopsy revealed a fatty degeneration with chromium concentration 3.6 umol/g. The kidney, with chromium concentration 2.6 umol/g, had extensive necrosis and ischemic lesions. Changes in renal function among ferrochromium workers in a ferroalloy facility in China were investigated (exposed to chromium compounds such a sodium-chromate and chromium-hydroxide). The results of this study suggest that long-term exposure to chromium produces chronic renal injury, mainly involving the proximal tubule. A urinary chromium concentration of greater than 15 ug/g of creatinine can be proposed as a threshold dosage for nephrotoxicity, and gamma-glutamyl-transferase, NAG and alkaline-phosphatase are all ea Source: Hazardous Substances Data Bank (HSDB)
- Toxicity Summary: Trivalent chromium may also form complexes with peptides, proteins, and DNA, resulting in DNA-protein crosslinks, DNA strand breaks, DNA-DNA interstrand crosslinks, chromium-DNA adducts, chromosomal aberrations and alterations in cellular signaling pathways. It has been shown to induce carcinogenesis by overstimulating cellular regulatory pathways and increasing peroxide levels by activating certain mitogen-activated protein kinases. It can also cause transcriptional repression by cross-linking histone deacetylase 1-DNA methyltransferase 1 complexes to CYP1A1 promoter chromatin, inhibiting histone modification. Chromium may increase its own toxicity by modifying metal regulatory transcription factor 1, causing the inhibition of zinc-induced metallothionein transcription.

- Environmental Bioconcentration: BCF values of soluble chromium(III) for bottom-feeding bivalves (oyster (Crassostrea virginica), blue mussel (Mytilus edulis), and soft shell clam (Mya arenaria)) range from 86 to 192(1).
