Copper - Wikipedia
Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposefully alloyed with another
Chloride | Lab Tests Online
Chloride is an electrolyte that works with potassium, sodium, and bicarbonate to help regulate the amount of fluid in the body and maintain the acid-base balance. A chloride test measures the level of chloride in the blood and/or urine.

Overall, calcium phosphates and metal oxides showed a significantly higher (p < 0.001) levels of arsenic and lead relative to other mineral sources (Table 2). This fact could be explained due to the fact that minerals such as Zn, Mn and Fe oxides have such redox potentials that can oxidize As and will thus alter the extent of As retention.
