Cadmium

MCL: 0.005 ppm

Source: Found naturally in rocks and minerals. Produced as a byproduct of smelting for zinc, lead, and copper. It is used in pigments, electroplating, and was formerly used in batteries.

Summary: Cadmium is element 48 on the periodic table of elements. It is found naturally in the crust of the earth in rocks and minerals associated with oxygen and sulfur. Cadmium is produced as a by-product of smelting for the more heavily used elements it is found with such as lead, zinc, and copper. Cadmium was formerly used in batteries with nickel (nickel-cadmium batteries). The element has many applications and is chosen especially for its non-corrosive properties in specialty areas such as aerospace engineering. It may also be used in electroplating for brake rotors among other materials. Cadmium is also used in pigments and in the production of photocells. It is known to accumulate in the environment. The element has a density of 8.69 g/mL at 25 C.
