In the textile industry, heavy metals are used to make certain pigments and dyes. In addition to this, in some natural fibers, heavy metals are encountered when the plants are fed from the soil. Another way of transmission of heavy metals to textile products and leather products is through finishing processes applied during finishing processes.

As a result of skin contact with skin, a number of heavy metals are absorbed by the skin and enter the body and accumulate in certain organs such as the liver or kidneys. When this accumulation rises to high levels, negative effects on human health begin to emerge. For example, lead, one of the dangerous heavy metals, threatens the nervous system.

The types of heavy metals that can be found in leather products are generally: antimony, arsenic, copper, lead, cadmium, chromium, mercury, cobalt and nickel. Heavy metals are naturally occurring elements in the earth. They are indestructible and indestructible. It is beneficial for the human body, provided that some are in small amounts, but is usually very dangerous. They usually enter the human body with foodstuffs, drinking water and inhaled air. One way is to contact the skin.

Among these, cadmium has been banned for many years in European Union countries. Lead is limited to a certain amount by legal regulations both in European Union countries and in our country.

Tests and analyzes are carried out by authorized laboratories to determine the amount of heavy metals that can be extracted from the skin within the scope of specific tests. In these studies, standards published by local and foreign organizations are taken into consideration. The standards for determining the amount of heavy metals that can be extracted in the skin are:

  • TS EN ISO 17072-1 Leather - Determination of metal content - Part 1: Extractable metals
  • TS EN ISO 17072-2 Leather - Determination of metal content - Part 2: Total metal content
