However, the dangers of calcium come from its compounds, especially calcium salts. Here's a breakdown:
1. Calcium Salts:
* Ingestion: Some calcium salts, like calcium chloride, can be quite irritating to the digestive system if ingested in large quantities. This can cause nausea, vomiting, and diarrhea.
* Skin and Eye Contact: Many calcium salts are caustic and can cause skin and eye irritation, burns, and even permanent damage if not handled properly.
* Inhalation: Dust from some calcium compounds can irritate the lungs and cause respiratory problems.
2. Specific Examples:
* Calcium oxide (Lime): This is a strong base that reacts violently with water, producing heat. Contact with skin or eyes can cause severe burns. Inhalation can cause lung irritation.
* Calcium carbide: This is a compound that releases flammable acetylene gas upon contact with water, posing a fire hazard.
* Calcium cyanamide: This is a nitrogen fertilizer that releases toxic ammonia gas upon exposure to water. It is also a potential skin and eye irritant.
3. Calcium Imbalance:
While not directly related to the element itself, it's important to note that calcium imbalances in the body can lead to serious health issues.
* Hypocalcemia (low calcium): Can cause muscle cramps, weak bones, and even seizures.
* Hypercalcemia (high calcium): Can cause kidney stones, constipation, and weakness.
4. Overall:
The risks associated with calcium primarily stem from its compounds and their interactions with water, air, and biological systems. It's important to handle calcium compounds with caution and wear appropriate protective gear. Always consult safety data sheets for specific information about handling and risks related to each calcium compound.
