Nickel - Heavy Metals Test

The average concentration of nickel in drinking water is around 2 ppb; Soil - soil generall contains about 4 - 80 ppm. unless the soil is near mining activities especially where nickel is extracted. It has been known for nickel concentration in these areas to be as high as 9,000 ppm.

2013-10-10 · Nickel concentrations in drinking-water in European countries of 2–13 µg/litre have been reported (28). An average value of 9 µg/litre and a maximum of 34 µg/litre were recorded in Germany (29). Nickel may, however, be leached from nickel-containing plumbing fittings, and levels of up to 500

Nickel | Ni - PubChem

Nickel is a very abundant natural element. Pure nickel is a hard, silvery-white metal. Nickel can be combined with other metals, such as iron, copper, chromium, and zinc, to form alloys.These alloys are used to make coins, jewelry, and items such as valves and heat exchangers. Most nickel is used to make stainless steel. Nickel can combine with other elements such as chlorine, sulfur, and ...

2020-1-21 · 1. Introduction. Nickel is a hard, ductile, silvery-white transition metal; it is the 28th element in the periodic table. It may exist in several oxidative states (from −1 to +4); nevertheless, the +2 oxidation state (Ni 2+) is the most widespread in the environment and biological systems [].Nickel belongs to the ferromagnetic elements, and it is naturally present in the Earth crust usually ...

Nickel concentrations in groundwater depend on the soil use, pH, and depth of sampling. The average concentration in groundwater in the Netherlands ranges from 7.9 µg/litre (urban areas) to 16.6 µg/litre (rural areas). Acid rain increases the mobility of nickel in the soil and thus might increase nickel concentrations in groundwater (IPCS, 1991).
