Heavy Metals

Industrial effluent streams can introduce heavy metal contamination into aqueous systems. Heavy metals (such as mercury, lead, cadmium, arsenic, copper, and nickel) can then migrate to any plant or animal life which uses this water. Fish and other aquatic life are obviously the most affected. Because heavy metals do not break down, they will bio-accumulate up the food chain. Atomic adsorption spectroscopy (AAS) and inductively coupled plasma (ICP) are the analytical techniques most often used to determine the presence and levels of heavy metals in foods, with hyphenated methods such as LC-ICP-MS being often used for speciation analysis. We offer multiple certified reference materials (CRMs) and high quality acids, bases and salts for the calibration and operation of AAS and ICP instruments.
