CADMIUM NITRATE is an odorless white solid. Sinks in water. (USCG, 1999)
Cadmium nitrate is an odorless white solid. Sinks in water. (USCG, 1999)
Cadmium nitrate is an odorless white solid. Sinks in water. (USCG, 1999)|Cadmium nitrate is an inorganic nitrate salt having Cd(2+) as the counterion. It has a role as a carcinogenic agent, a hepatotoxic agent and a genotoxin. It is a cadmium salt and an inorganic nitrate salt. It contains a cadmium(2+).|Cadmium Nitrate is a colorless, crystalline, inorganic compound that forms toxic fumes of cadmium oxides when heated. Calcium nitrate is used in the production of cadmium hydroxide for use in alkaline batteries, to color glass and porcelain, in photography and in nuclear reactors. Exposure to this substance irritates the eyes, skin and respiratory tract and causes damage to the lungs resulting in shortness of breath, chest pain and pulmonary edema, and can also damage the kidneys causing proteinuria and decreased renal function. Calcium nitrate is a known carcinogen and is associated with an elevated risk of developing lung cancer. (NCI05)

Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Cadmium nitrate is included on this list.
The major hazards encountered in the use and handling of cadmium nitrate stem from its toxicologic properties. Toxic primarily by ingestion and inhalation, exposure to this odorless, colorless-to-white, crystalline substance may occur from its use in making other cadmium salts, in photographic emulsions, in coloring glass and procelain, and in the manufacture of nickel-cadmium batteries and turf fungicides. Effects from exposure may include headache, nausea, shortness of breath, chest pain, kidney damage, liver damage, emphysema, and intense pulmonary edema (possibly resulting in death). Processes and operations which may release cadmium fumes or dust should be enclosed and fitted with exhaust ventilation. In activities where overexposure is possible, workers should wear a high efficiency particulate filter respirator or self-contained breathing apparatus. Protective clothing also should be worn, including eye, face, and hand protection. All such clothing should be removed before leaving work. If contact should occur, immediately wash contaminated skin with large amounts of water. Do not eat, smoke, or drink in work areas. Cadmium nitrate presents only a moderate fire hazard (when in the form of dust) if exposed to heat, flame, or by chemical reaction with oxidizing agents, metals, hydrogen azide, zinc, selenium, or tellurium. Wear a self-contained breathing apparatus when fighting such fires. Cadmium nitrate should be stored in cool, well-ventilated areas, out of direct rays of sun, and away from combustibles and other fire hazards. Should hazardous concentrations of cadmium nitrate be released, first stop the discharge, then isolate and remove the discharged material. Before implementing land disposal of waste cadmium nitrate, consult environmental regulatory agencies for guidance.

Toxicity
highly toxic
In order to test the potential effect of prior exposure to different Cd concentrations on Cd uptake and accumulation, plants of Arabidopsis thaliana, including a phytochelatin-deficient mutant, cad1-3, and the wild type, were compared. For Cd uptake experiments, plants were grown for 1 week in nutrient solution containing different Cd concentrations (0, 0.05, 0.1, 0.25, 0.5, and 1.0 uM Cd(NO3)2). Thereafter they were subjected to 0.5 uM Cd labelled with (109)Cd for 2 hr. Uptake experiments with (109)Cd showed that the phytochelatin-deficient mutant cad1-3, accumulated less Cd than the wild type. Both a lower proportion and lower total amount of absorbed Cd were translocated to the shoot in cad1-3 plants compared to wild-type plants. Cadmium exposure also influenced the amounts of nutrients found, whereby after exposure to high Cd concentrations (0.5, 1.0 uM) during growth, cad1-3 roots contained less Fe, K, Mg, P, and S compared to roots of the wild type. In cad1-3 these elements decreased with increasing Cd concentration. The total Cd content in roots and shoots increased significantly with increasing Cd concentration during growth, although the increase was much less in cad1-3 plants. In time-dependent experiments of Cd uptake carried out between 15 and 120 min on plants not previously exposed to Cd, no significant difference in Cd accumulation between the mutant and wild type were found, although a smaller amount of Cd was translocated to the shoot in cad1-3 plants. The possibility that the differences in Cd accumulation in mutant and wild-type lines may be due to the cytosolic Cd regulation, which is inhibited by the complexation of Cd by phytochelatins, is discussed|The interaction between selenium and cadmium was studied in relation to cellular uptake and expressions of selenium-cadmium interaction. Human K-562 cells were pre-treated or simultaneously treated with (5 or 50 uM) selenite or (10 or 50 uM) selenomethionine and with (60 or 75 uM) cadmium nitrate. Cells pre or simultaneously treated with selenite revealed increased cadmium concentration with increased doses of selenite, particularly pronounced in the simultaneous treatments. In both treatments, selenium protection was observed during the exposure period, but not during the growth period. In cells simultaneously treated with selenomethionine and 60-uM cadmium, an increase in cadmium concentration was observed after increased selenium dose. In addition, it was found that simultaneous selenomethionine treatment with 60-uM cadmium resulted in selenium protection during the exposure period, although protection was not observed during the growth period.|Plants that hyperaccumulate metals are ideal subjects for studying the mechanisms of metal and mineral nutrient uptake in the plant kingdom. Indian Mustard (Brassica juncea) has been shown to accumulate moderate levels of Cd, Pb, Cr, Ni, Zn, and Cu. In this experiment, 10 levels of Cd concentration treatments were imposed by adding 10-190 mg Cd /per/ kg to the soils as cadmium nitrate [Cd(NO3)2]. The effect of Cd on phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and the micronutrients iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) in B. juncea was studied. Plant growth was affected negatively by Cd, root biomass decreased significantly at 170 mg Cd /per/ kg dry weight soils treatment. Cadmium accumulation both in shoots and roots increased with increasing soil Cd treatments. The highest concentration of Cd was up to 300 mg /per/ kg dw in the roots and 160 mg /per/ kg dw in the shoots. The nutrients mainly affected by Cd were P, K, Ca, Fe, and Zn in the roots, and P, K, Ca, and Cu in the shoots. K and P concentrations in roots increased significantly when Cd was added at 170 mg /per/ kg, and this was almost the same level at which root growth was inhibited. Zn concentrations in roots decreased significantly when added Cd concentration was increased from 50 to 110 mg /per/ kg, then remained constant with Cd treatments from 110 to 190 mg /per/ kg. However, Zn concentrations in the shoots seemed less affected by Cd. It is possible that Zn uptake was affected by the Cd but not the translocation of Zn within the plant. Ca and Mg accumulation in roots and shoots showed similar trends. This result indicates that Ca and Mg uptake is a non-specific process.|We examined the influences of three trace metals on the accumulation of a major nutrient (NO3-) in Scenedesmus quadricauda. A comparative study on metal-nutrient interaction in free and immobilized states of algal cells was conducted. The effect due to interaction between different variables (cell state type, metal type, and metal dose) was studied to assess the variation in the nitrate uptake by free and immobilized cells. The results analyzed by ANOVA (three-way) (components: cell state type, metal type, and metal dose) confirmed that the inhibition of nitrate uptake by test metals was highly significant (P<0.001). Free and immobilized states of S. quadricauda responded differently (P<0.05, ANOVA) to the types of metal added. Uptake kinetics was studied by monitoring short-term uptake rates at different nutrient levels. Free and immobilized cells of the organism displayed noncompetitive modes of inhibition for Ni and Zn while a competitive mode of inhibition by Cd was observed in both free and immobilized states of the organism.|For more Interactions (Complete) data for CADMIUM NITRATE (6 total), please visit the HSDB record page.

Drug Information
A meta-analysis of existing scientific literature recently suggested that Cd is absorbed more efficiently by sheep if it is in the organic form in grass, than if it is added as an inorganic supplement to the diet. We tested this experimentally by feeding sheep grass from contaminated soil, compared with uncontaminated grass and with Cd added to the diet. To produce contaminated herbage, Cd nitrate was added to soil in 11 lysimeters sown with perennial ryegrass, with a further 11 lysimeters receiving no Cd to produce uncontaminated herbage. In the Cd-treated lysimeters, soil had increased exchangeable K, Mg, and Ca, leachate had increased K, Mg, Ca, Na, and P, grass had increased Cd and reduced Mg, Na, P, Mn, Fe, Cr, Al, and Ni, and there was some reduction in grass yield compared with untreated lysimeters. Grass from Cd-treated or untreated lysimeters was fed to groups of 12 ewes for 2 days, with Cd intake equated by adding Cd nitrate to the concentrate feed of ewes receiving the uncontaminated grass. The apparent absorption of Cd, Zn, Mo, Cr, and Al was increased for ewes receiving Cd-enriched grass, and apparent absorption of Cu was reduced, compared to those receiving supplementary inorganic Cd. Most of the unabsorbed Cd was excreted in feces within 4 days of feeding. The ewes consuming Cd in grass had increased B concentrations in their urine, possibly due to adverse effects of Cd on kidney function. Finally, the ewes were offered a choice of the two herbages and they ate significantly more of the uncontaminated grass. It is concluded that the apparent absorption of Cd and other heavy metals by sheep in a short-term experiment was greater when Cd was in the grass than when the Cd was added in in an inorganic form and that sheep partially avoided herbage with a high Cd concentration.

/ALTERNATIVE and IN VITRO TESTS/ Effects of some metals on the growth of cultured human erythroleukemia K-562 cells were investigated when grown in two different types of media based upon RPMI-1640 or Ham's F-10. The study on proliferation, using RPMI-1640 supplemented with sodium selenite, selenomethionine, mercuric chloride, methylmercuric chloride and cadmium nitrate showed no inhibition of growth at concentrations of 2.5, 25, 25, 2.5 and 25 uM, while at 75, 250, 50, 5 and 50 uM toxicity was apparent. Selenite at 5-50 uM and selenomethionine at 50-100 uM inhibited the growth. In Ham's F-10 supplemented with the same compounds no inhibition was found at concentrations of 5, 10, 25, 1 and 50 uM, while at 50, 100, 50, 5 and 75 uM toxic effects were noted. Selenite 10 uM and selenomethionine 25-50 uM inhibited the proliferation. Measurements of trace element levels in pellets of K-562 cells grown in RPMI-1640 or Ham's F-10 unveiled higher cell contents of cadmium and selenium in cells grown in RPMI-1640, being consistent with higher concentrations of these elements in that medium. Manganese and mercury concentrations were higher in cells grown in Ham's F-10 correlating with a higher medium concentration of these elements. The growth responses and cellular uptake differed between the metals and the selenocompounds and although extrapolating the results to humans is difficult the selenium exposures were in approximately the same order of magnitude as in human exposures. The compounds could be ranked according to decreasing toxicity as: methylmercuric chloride > mercuric chloride, cadmium nitrate, sodium selenite > selenomethionine.|/ALTERNATIVE and IN VITRO TESTS/ Recent reports, highlighting the relationships of cadmium exposure and vascular diseases, indicated that vascular endothelial cell was the target of cadmium (Cd) toxicity. However, the underlying mechanisms have not been fully elucidated. ...this study...evaluated the internalization of Cd(2+) into human umbilical vein endothelial cells (HUVECs) by a novel Cd(2+)-selective sensor suitable for living cells. Then, we detected apoptosis in the treated cells. Our results showed that Cd(2+) at low concentrations (< 10 umol/L) inhibited apoptosis induced by deprivation of serum and basic fibroblast growth factor (bFGF). To investigate the corresponding molecular mechanisms, we employed acridine orange staining and Western blotting of /microtubule-associated protein 1 light chain 3 alpha/ MAP1 LC3 to detect autophagy, and analyzed the levels of integrin beta4, caveolin-1 and activity of /phosphatidylcholine-specific phospholipase/ PC-PLC. Our results showed that low concentrations of Cd(2+) promoted autophagy and depressed the levels of integrin beta4, caveolin-1 and PC-PLC activity. The data suggested that autophagy played a key role in Cd(2+) induced endothelial dysfunction; integrin beta4, caveolin-1 and PC-PLC might be the targets of Cd(2+) in vascular endothelial cells
