The heavy metal testing market is projected to reach USD 3.65 billion by 2022, at a CAGR of 7.6% from 2017. The market is driven by factors such as the increasing pollution in water due to heavy metals in industrial discharge, a stringent regulatory environment, and the increasing number of food recalls for the safety of consumers. The high-growth potential in emerging markets and untapped regions provide new growth opportunities for market players.

The arsenic segment dominated market for food and is projected to grow at the highest CAGR from 2017 to 2022. Arsenic is the most harmful heavy metal contaminant in the food industry, especially in foods that require high amounts of water for processing. The element exists in both inorganic and organic forms; inorganic arsenic compounds such as arsenic trichloride are considered to be extremely toxic because of their higher levels of carcinogenesis. Hence, heavy metal testing for arsenic is growing.

The ICP-MS & OES segment for food testing is projected to grow at the highest CAGR from 2017 to 2022. The speed & reliability of this technology is superior as compared to the other technologies such as AAS and volumetric technologies. This technology has automated approach to testing, which provides quick results.

The blood & other samples segment is projected to be fastest-growing between 2017 and 2022. Heavy metal testing in cellular samples is widely conducted for blood & other samples including urine, serum, and saliva samples. As a result of the growing pollution levels and food & water contamination, the level of toxicity in the environment is increasing rapidly. Once inside the body, toxic metals can cause tissue destruction, functional disturbances, and the general weakening of an individual’s resistance to illness. A heavy metals test measures the quantity of specific potentially toxic metals in the blood, urine or, more rarely, in the hair or other body tissue or fluids.

The Asia Pacific region accounted for a significant share in the heavy metal testing market in 2016, and is also projected to grow at the highest CAGR during the forecast period. This region has high potential for heavy metal testing in various samples. The requirement for heavy metal testing has grown in recent years owing to the high concentration of heavy metals in the agricultural lands of China and Japan. Manufacturers are focusing on heavy metal testing to meet international standards and be applicable for global trade.
