Clean Air Act: CAS# 1313-13-9 (listed as Manganese compounds, n.o.s.) Manganese Essentiality, transporting characteristics and toxicity of manganese Manganese (Mn) is a trace metal commonly found in the environment. (2011, 2012) found the pallidal nuclei to be more susceptible to manganese accumulation compared with the caudate and putamen in welders with high occupational exposure to manganese. Studies in neonatal animals have detected structural and neurochemical changes at doses of Mn similar to or slightly above dietary levels (1–10 mg Mn/kg/day) (Chandra and Shukla, 1978; Deskin et al., 1980), suggesting that young animals might be more susceptible to Mn than adults. Studies in Caenorhabditis elegans have shown that Mn has the ability to induce DAergic-specific neurodegeneration. Organic Mn crosses the BBB by passive diffusion. Prepared from the mineral Pyrolusite and from other ores. The CNS of neonatal rats was found to be more susceptible to Mn-induced neurotoxicity compared with the adult rat CNS (Kontur and Fechter, 1988). : 1313-13-9 EC-No. Changes in laboratory values (full blood count, electrolytes, serum creatinine, and liver function tests) and vital signs (pulse, blood pressure) were generally transient, not clinically significant, and did not require treatment. Although manganese exposure can occur through several different forms, including ingestion of food and exposure to manganese-containing products, exposure in an occupational setting such as mining, smelting, and welding appears to be a major contributor to these toxicants. AC203191000, AC203195000, AC213490000, AC213490010, AC213490250, Mn-SOD is one of the cell’s primary defenses against oxygen-derived free radicals and is vital for maintaining a healthy balance between oxidants and antioxidants (Flores et al., 1993).   MSDS Name: Manganese(IV) dioxide We use cookies to help provide and enhance our service and tailor content and ads. In toxic concentrations, the detrimental effects of Mn on human health include childhood developmental disorders and manganism. (1993) demonstrated reduced body weight of mice during development after exposure to 8 or 16 mg/kg Mn (II). AC222580000, AC222580050, AC222580500, AC222581000, AC222585000, Manganese or potassium ignites in nitrogen dioxide [Ann. Thomas P. Moyer, in Pharmacology and Therapeutics, 2009, Manganese is widely distributed in the environment and is an essential trace element. Manganese compounds were in use in prehistoric times; paints that were pigmented with manganese dioxide can be traced back 17,000 years. 13. Manganese dioxide is a heavy metal oxide, and is reasonably toxic. However, the disturbance is likely to occur at different points within the complex neuronal pathways in the basal ganglia (Roth, Li, Sridhar, & Khoshbouei, 2013). Calabresi et al.   Skin: The diet has to include foods with little manganese (ie. AC357790000, AC357790050, AC357790500, S75734, S75737, S93297, S93298,   Other studies showed that expression of D2–DA receptors (D2R) is downregulated in the basal ganglia and the midbrain following Mn exposure (Butterworth, Spahr, Fontaine, & Layrargues, 1995; Mousseau, Perney, Layrargues, & Butterworth, 1993; Sriram, Lin, Jefferson, Roberts, Chapman, et al., 2010). Manganese dioxide decomposes above about 530 °C to manganese(III) oxide and oxygen. Cumulative evidence has established that Mn exposure induces signs and symptoms similar but not identical to Parkinson’s disease (Tuschl et al., 2013; Rutchik et al., 2012; O’Neal and Zheng, 2015; Kwakye et al., 2015; Guilarte and Gonzales, 2015). One had mild hepatic dysfunction. Uses advised against Not for food, drug, pesticide or biocidal product use Details of the supplier of the safety data sheet : M108, M108-500 CAS-No 1313-13-9 Synonyms Manganese dioxide Recommended Use Laboratory chemicals. It functions as Regardless of the controversy, several reports have confirmed the effects of manganese exposure on the brain, particularly nuclei of the basal ganglia. to the accumulation of dark crystals of insoluble manganese dioxide in tissues within or alongside the veins (1, 3), and ... from manganese toxicity is displayed most notably in the cabbage family (Brassica spp.) Potassium permanganate is used in water purification, manganese dioxide in the manufacture of dry batteries and fireworks, manganese chloride in animal feed, and manganese sulfate as a fertilizer. Injection-associated reactions included heat (49%) and flushing (39%). The hallmark of PD is the degeneration of the nigrostriatal DAergic neurons in the substantia nigra pars compacta that innervate the caudate and putamen. The Egyptians and Romans used manganese compounds in glass-making, to either remove color from glass or add color to it. It is also possible that Mn-SOD might have a critical role in Mn toxicity because either an Mn deficiency or an excess dose of Mn can alter Mn-SOD activity (Borello et al., 1992; Davis and Greger, 1992; Hirose et al., 1993; Cobbs et al., 1996). 1 mg/m3 TWA (as Mn) (listed under Manganese compounds, n.o.s. high amounts of manganese include an increased incidence of cough Manganese Dioxide tech CAS No 1313-13-9 MATERIAL SAFETY DATA SHEET SDS/MSDS. May cause adverse reproductive effects based upon animal   Early symptoms include sluggishness, sleepiness, and weakness in the legs. Testes weights in males were significantly decreased from controls only when Mn was administered in conjunction with an iron-poor diet (Laskey et al., 1982). have been reported in animals. ), the univalent reduction product of dioxygen (Coassin et al., 1992; Singh et al., 1992; Tampo and Yonaha, 1992). Mn was suggested to mediate oxidation of extracellular DA, which, after uptake via DAT, may cause oxidative injury and degeneration of DAergic neurons (Chakraborty & Aschner, 2012). 0.2 mg/m3 TWA (as Mn) (listed under Manganese, inorganic compounds). The effect of MnCl2 on the activities of SOD and GPx and its effect on GSH content were evaluated in different regions of rat brain after administration at 2.5 or 5 mg MnCl2/kg. 5 mg/m3 Ceiling (as Mn) (listed under Manganese compounds, n.o.s. Recent work in nonhuman primates (Guilarte et al., 2008) detected Mn-induced brain gene expression changes associated mainly with genes affecting apoptosis, protein folding and degradation, inflammation and axonal/vesicular transport. Formation of Mn(III) may occur by oxidation of Mn(II) by superoxide (Hussain et al., 1997). Mn at a 5000 ppm dietary level is lethal to preruminant calves (Puls, 1994). Has shown teratogenic effects in laboratory animals. Oxidative stress generated through mitochondrial perturbation may be a key event in the demise of the affected central nervous system cells. The majority of these exposures are via inhalation of manganese dust, as in mining, or volatilization and inhalation of manganese fumes from manganese substrates during smelting and welding (Huang et al., 1989; Hudnell, 1999). In high doses, manganese may increase anemia by For further details on Mn-induced reproductive and developmental effects, readers are referred to a recent publication (Milatovic et al., 2017). Manganese Essentiality, transporting characteristics and toxicity of manganese Manganese (Mn) is a trace metal commonly found in the environment. Animal studies have shown that Mn exposure decreased the growth of reproductive organs (preputial gland, seminal vesicle and testes) (Gray and Laskey, 1980). Mn-SOD activity was not altered in the caudate nucleus or frontal cortex, however, there was a significant increase of Mn-SOD activity in the hippocampus (Fig. It can exist in oxidation states from -3 to +7, the most common being +4 in the chemical form of manganese dioxide (Keen and Leach 1988). The general toxicity of manganese and its neurotoxicity [ 8] have been reviewed. The specific area of injury in humans seems to be primarily in the globus pallidus. In terms of the neurochemistry of manganese toxicity, some other studies have shown that dopamine levels are affected by manganese exposure in humans, monkeys, and rodents, with various indications of an initial increase in dopamine followed by a longer-term decrease (Barbeau, 1984; Donaldson, 1984). Significant differences across the different groups were evaluated by ANOVA, and p values (< 0.05) are indicated (*) on the top of the bars. By continuing you agree to the use of cookies. In the case of Pseudokirchneriella subcapitata, manganese dioxide powder should be used as an alternative quenching agent to catalase, since this enzyme exhibited a highly toxic … In Meyler's Side Effects of Drugs (Sixteenth Edition), 2016.   Investigated as a reproductive effector. Exposure to high levels of airborne manganese has been associated with several neurologic symptoms, including reduced neurobehavioral performance and neuropsychologic impairment (Huang et al., 1993; Gibbs et al., 1999). The general toxicity of manganese [7] and its neurotoxicity [8] have been reviewed. Manganese peroxide; Manganese binoxide; Manganese black; Battery The SOD activity is expressed as units/mg of protein; mean ± SEM for 6–8 animals per group. Figure 12. Studies with primary astrocyte cultures have revealed that they are a critical component in the defenses against manganese-induced neurotoxicity (Dobson et al., 2004). manganese; Manganese superoxide; occurs in nature as the mineral CNS depression. Target Organs: Central nervous system, lungs, The precise biochemical mechanism by which manganese leads to selective destruction of dopaminergic neurons is not known, but many researchers believe that manganese ion enhances the autooxidation or turnover of various intracellular catecholamines, leading to increased production of free radicals (Donaldson et al., 1982), reactive oxygen species, and other cytotoxic metabolites, along with a depletion of cellular antioxidant defense mechanism (Barbeau, 1984; Donaldson, 1987; Graham et al., 1984; Liccione and Maines, 1988; Nachtman, 1986; Verity, 1999).
