calcium carbonate inhalation toxicity

Haematology results, clinical chemistry analysis and necropsy findings did not show any treatment-related changes. 1. Suspected ammonium nitrate fertiliser poisoning in cattle. Calcium metal is hazardous because of its sometimes-violent reactions with water and acids. Bienvenue sur le site web de l'ECHA. First-aid measures after skin contact : Wash with water and soap. All carbonate salts are on the FDA generally regarded as safe list. The results of this study are read across to bulk calcium carbonate. Paper fabrication; Plastic fabrication; Ceramics; Toxicology. However, these effects are more prevalent in those people suffering from renal insufficiency and following the ingestion of high doses of calcium (well above the recommended classification limits for STOT RE as defined in the Guidance on the Application of Regulation (EC) No 1272/2008). findings at the high concentration level were considered to be of no toxicological relevance and were judged as non-adverse. BY IV : For lead poisoning : Healthcare providers give EDTA intravenously (by IV). - Confusion, bizarre or aggressive behavior. Calcium Carbonate 471-34-1 100 Section 4 First Aid Measures Emergency and First Aid Procedures Inhalation: In case of accident by inhalation: remove casualty to fresh air and keep at rest. MI11214 Revision date 25/Jun/2015 Reproductive toxicity This product does not contain any known or suspected reproductive hazards. CAS Number : 471-34-1. Identification . The circumstances leading to the incident included the method of application of the fertiliser, low rainfall and the absence of subsequent irrigation of the fertilised pastures. Uncoated nano calcium carbonate was administered by gavage to three groups, each of ten male and ten female Wistar rats, for up to forty-eight consecutive days (including a two week maturation phase, pairing, gestation and early lactation for females), at dose levels of 0, 100, 300 and 1000 mg/kg bodyweight/day. Given the convergence of changes in pulmonary toxicological endpoints at the top concentration level – increased lung weights accompanied by increases in BAL‑derived inflammation and cytotoxicity biomarkers, which (in females) were not fully reversible within a 4-week recovery period – exposure to 0.399 mg/L uncoated nano calcium carbonate was considered to have resulted in an adverse response in the lower airways. Kidney function: Some studies have indicated that perimenopausal women with total calcium intakes between 2 and 3 g/day may show a tendency for compromised glomerular function as indicated by increases in serum creatinine. Exposure to 0.212, alcium carbonate (nano) resulted in very limited alterations in BAL parameters only. Therefore, the findings at the high concentration level were considered to be of no toxicological relevance and were judged as non-adverse. The occurrence of a suspected mixed ammonia and nitrate fertiliser poisoning that led to acute illness and fatalities in cattle is described. Calcium metal is found in some drain cleaners, … It is expected to partition strongly to water rather than organic media. Sensibilisation . The NOAEC was 0.212 mg/L. It is widely held (though at times hotly debated 2, 3) that calcium administered in the setting of digoxin toxicity will probably induce arrhythmia or cardiac arrest. This article is for information only. The content is subject to change without prior notice.Reproduction or further distribution of this information may be subject to copyright protection. Under the conditions of the current study, inhalation exposure to 0.399 mg/L uncoated nano calcium carbonate resulted in treatment-related changes in the lower airways, characterized by an increased lung weight accompanied by slight increases in BAL‑derived inflammation and cytotoxicity biomarkers. The aim of the present study was to provide data on the sub-chronic (13‑week) toxicity of inhaled calcium carbonate (nano) in rats. Particle size distribution (Granulometry), Solubility in organic solvents / fat solubility, Stability in organic solvents and identity of relevant degradation products, Storage stability and reactivity towards container material, Biodegradation in water and sediment: simulation tests, Additional information on environmental fate and behaviour, Short-term toxicity to aquatic invertebrates, Long-term toxicity to aquatic invertebrates, Toxicity to aquatic algae and cyanobacteria, Toxicity to aquatic plants other than algae, Endocrine disrupter testing in aquatic vertebrates – in vivo, Toxicity to soil macroorganisms except arthropods, Endocrine disrupter mammalian screening – in vivo (level 3), Direct observations: clinical cases, poisoning incidents and other, Exposure related observations in humans: other data. Horner RF. Therefore, a classification as STOT RE is not justified and no classification is proposed. [1] BAL measurements are usually a rather sensitive toxicological read-out parameter, and it is not uncommon to observe treatment-related changes at concentrations below a level at which histopathology is induced. Cases of calcium supplements poisoning most often result when a canine family member discovers a supply of human calcium chews. sur la façon dont nous utilisons les cookies. The exposure to the test material was well tolerated by the animals. The NOAEL was therefore reported to be 1300 mg/kg bw/day. Calcium toxicity refers to an overabundance of calcium within the human body, also known as hypercalcemia.It can result from medical complications that include diseases and hormone imbalances or from excessive calcium intake. Not irritant to skin. It has a strong chlorine odor, but odor may not provide an adequate warning of hazardous concentrations. On dietary calcium intakes in the range of the recommended dietary intake the risk of nephrolithiasis is determined by other dietary components and by genetic factors. The results of this study are read across to bulk calcium carbonate. Potential Adverse human health effects and symptoms : Practically non-toxic if swallowed (LD50 oral, rat > 2000 mg/kg). Symptomatic hypocalcemia, hyperkalemia. Immediately call a doctor. [Calcium carbonate poisoning]. However, no such effect was observed in another study with women receiving comparable calcium amounts. Mise à jour : 2005-09-28. Calcium carbonate is commonly found in antacids (for heartburn) and some dietary supplements. Thus, the NOAEL for uncoated nano calcium carbonate in this study was >1000 mg/kg bw/day. 453/2010 01/05/2015 EN (English) 2/5 SECTION 4: First aid measures 4.1. 4). 1 Material Safety Data Sheets Calcium Carbonate • Looe in te Lab • Loose in the Lab, Inc. Issue Date 6/11/2015 9462 South 560 West ... of inhalation. To assess recovery or delayed occurrence of toxicity, two groups of 10 male and 10 female animals each. Repeat dose toxicity - inhalation: A 90 day inhalation toxicity study in the rat is has been performed using uncoated nano calcium carbonate in which no systemic toxicity was observed. I-Acute Exposure A-Inhalation CAS Number : 471-34-1. The exposure conditions were close to their respective targets. Therefore, it is not clear whether this finding can be attributed to the ingestion of calcium. Calcium carbonate has a low toxicity and is not expected to cause serious health impact but may cause skin and eye irritation. 77, No. Give10% calcium gluconate, 10–20 mL (children, 0.2–0.3 mL/kg), or 10%calcium chloride, 5–10 mL (children, 0.1–0.2 mL/kg), slowly IV. DO NOT use it to treat or manage an actual poison exposure. Local effects were observed in the lung, these were irritation and increased lung weights. Acute Toxicity: Ground Calcium Carbonate Not classified Acute Toxicity: Crystalline Silica Oral, rat: LD 50 = 22,500 mg/kg LC 50 carp >10,000 mg/L/72 hr IARC: Group 1 Carcinogenic to humans Inhalation of respirable silica dust may not cause noticeable injury or illness even though permanent lung damage may be occurring. . Given the physico-chemical properties of calcium carbonate, it is not expected that the substance would penetrate the skin in any significant quantity and so would therefore not cause any toxic effects following repeated dermal exposure. Please upgrade your Internet Explorer to a newer version. Furthermore, as calcium carbonate is used as a food additive with an ADI not allocated, it can be concluded that intake of calcium carbonate should not pose a need for concern regarding its toxicity via the oral route. It generally has a low ecotoxicity. Ammonium Bicarbonate, Ammonium Carbonate, Calcium Carbonate, and Potassium Carbonate that are accessible at the European Chemicals Agency’s (ECHA) website. Acute calcium poisoning is rare, and difficult to achieve unless calcium compounds are administered intravenously. The document prepared by the Scientific Committee on Food describes a number of potential adverse effects following calcium supplementation. High calcium levels can also cause serious heart rhythm disturbances. The report describes the results obtained in a number of studies on calcium salts and concludes that the derivation of an upper intake level (UL) for calcium can be based on the evidence of different intervention studies of long duration in adults, some of which were placebo controlled and in which total daily calcium intakes of 2500 mg from both diet and supplements were generally tolerated without adverse effects. Calcium CARBONATE supplements, specifically, is an acid neutralizing alkali which is why it is used in over the counter 'Antacid' tablets and why it can contribute to calcium toxicity. Repeat dose toxicity - oral: A 14 day range finder study, a 28 day and a 90-day repeat dose oral toxicity study in rats are available that have evaluated the repeated dose toxicity of uncoated nano calcium carbonate. In these reports the supplemental calcium intakes were reported as between 1.0 and 23 g/day. Veuillez mettre à jour Internet Explorer. Calcium hypochlorite is not flammable, … This article is for information only. Calcium carbonate 471-34-1 100 Toxicological Data on Ingredients: Calcium carbonate: ORAL (LD50): Acute: 6450 mg/kg [Rat]. Furthermore, the safety assessment has been revised to include data from the REACH dossier on ammonium carbamate: acute inhalation toxicity data on ammonia (LC Molecular formula : CaCO 3. The exposure to the test material was well tolerated by the animals. Section 3: Hazards Identification Potential Acute Health Effects: Hazardous in case of eye contact (irritant). Information on Registered Substances comes from registration dossiers which have been assigned a registration number. No indications for systemic toxicity of inhaled calcium carbonate (nano)were observed in this study. BAL measurements are usually a rather sensitive toxicological read-out parameter, and it is not uncommon to observe treatment-related changes at concentrations below a level at which histopathology is induced. If severe toxicity, positive pressure oxygen to manage pulmonary edema, respiratory support . It is often added to other fertilizers, and composts. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). These findings were not substantiated by any concomitant changes in lung weight or treatment-related histopathology.
