Heavy metal pollution according to natural and anthropogenic resources is an international problem. Amongst heavy metals, nickel is a contaminant, which collects in soils, plants, animals, and aquatic systems. The nickel (Ni) concentration ranges in soil and drinking water is from 10 – 1000ppm and 6µg/l orderly. The nickel concentration in natural vegetation is between 0.05 and 5mg/kg of dry weight. The nickel portion penetrating the human respiratory is between 0.1 and 0.7µg/day. 100-200 µg of nickel is used each day including nickel cookery dishes. Everyday input of nickel from food is approximately 170µg orderly. The nickel level in seawater and river includes about 0.5 to 2ppb and 0.3ppb orderly. The normal smoke of a cigarette includes approximately 0.04 to 0.58 µg of nickel. Nickel is in the milk of humans and cows at a concentration between 0.001 to 0.1 mg/l orderly. The nickel resources include rocks and soil weathering, forest fires, fertilizers, industrial garbage, sewage, and sludge that includes a high amount of nickel. Nickel is an important factor needed for the plant's healthy growth, animals, and soil microbes, influences the photosynthetic processes of high plants, generates critical and chronic illnesses in humans, and decreases soil fertility. This study demonstrates the effects, significance, and poison of nickel.
