Saltwater intrusion - Wikipedia

The salts of hydrochloric acid contain chloride ions and can also be called chlorides. The word chloride can also refer to a chemical compound in which one or more chlorine atoms are covalently bonded in the molecule. The simplest example of an inorganic covalently bonded chloride is hydrogen chloride, HCl.

Heavy Metals Toxicity and the Environment

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological appliions have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.
