Nickel is a heavy metal with many health hazards. The most common mode of transport is cigarette smoke. In addition, a large amount of nickel is stored in plants. Human health can have fatal consequences ranging from cancer. It is known that a high proportion of nickel is present in foodstuffs, especially in chocolate and fats. People get nickel most by inhalation, by drinking water and by consuming foods. Although a small amount of nickel is necessary for the human body, it is dangerous to human health if it is overdosed. In the meantime, batteries should be used with the greatest care in daily life. Batteries contain toxic heavy metals such as lead, mercury, cadmium and nickel.

Nickel balance in the alloys and coatings of leather garments, which have a special place in textile products, is important for the enterprises operating in this sector. Skin products containing direct and prolonged contact with human skin should therefore be analyzed.

Laboratories are accredited in accordance with the TS EN ISO / IEC 17025 standard from the domestic or foreign accreditation organizations in order to be qualified and reliable in their measurement, test and analysis studies and for the validity of the reports they prepare.

Within the scope of chemical and ecological studies, measurements and analyzes are performed in authorized laboratories to determine the amount of nickel spot in textile products. The standards adopted in these studies are as follows:

• DIN EN 12471 Screening test for nickel balance of alloys and coatings in consumer products with direct and long-term contact with leather

This European standard provides a rapid screening method based on the use of dimethylglyoxime, which is suitable for the detection of nickel release of substances that come into direct and prolonged contact with the skin, referring to nickel allergy.
