What is Chloride?
Chloride is a chlorine anion that forms the negatively charged part of many salts. It is the most common inorganic anion in water and wastewater. Natural sources of salt are the ocean and salt deposits above and below ground. It is an essential electrolyte in all body fluids for maintaining acid/base balance, transmitting nerve impulses, and regulating fluid flow in and out of cells. Chloride is very corrosive to most metals in systems with elevated pressures and temperatures such as boilers and oil-drilling equipment. Chloride plays an important role in desalination, which removes chloride salts to make potable water.
Chloride Exposure and Health Risks
Direct contact can cause an allergic skin reaction. Health risks depend on the other ion present with chloride. Sodium chloride, known as table salt, is harmless. Calcium, magnesium, and potassium chlorides have varied uses ranging from medical treatments to de-icing to cement formation. Hydrogen chloride can be extremely dangerous and even toxic.
