ZINC AND THE ENVIRONMENT
A NATURAL COMPONENT OF THE ENVIRONMENT
ZINC IN INDUSTRY
Zinc is a chemical element that was first discovered around 1500 B.C. in Asia. It did not appear in Europe until the 17th century.
Zinc is a highly recyclable material. Recovered zinc accounts for approximately 30% of global supply and comes from sources such as brass components, galvanized steel from the automotive industry, household appliances, and residues from the galvanizing process (e.g., ash, furnace dust, and foundry returns).
Although it is difficult to determine the exact amount of zinc being recycled worldwide, it is estimated that nearly 2 million tons are reused in industrial applications each year.
EFFECTS ON HUMAN HEALTH
In the human body, zinc is one of the most essential trace elements. It is necessary for the proper functioning of over 300 enzymes, the stabilization of DNA, and signal transmission within the human nervous system.
According to the World Health Organization (WHO), the recommended daily intake of zinc is 10 mg for children, 12 mg for women, and 15 mg for men.
An average adult body contains about 3 grams of zinc, mainly stored in the bones and muscles.
The primary dietary sources of zinc include beef, poultry, fish, whole grains, shellfish, and dairy products. This element plays a role in numerous processes such as metabolism, bone mineralization, wound healing, immune system function, insulin secretion by the pancreas, and the regulation of vitamin A and cholesterol levels. It also contributes to blood pressure regulation and heart rhythm control.
Zinc levels can also be supplemented through appropriate dietary supplements. One noteworthy initiative is “Zinc Saves Kids”, a program supported by UNICEF and launched by the International Zinc Association (IZA). The initiative aims to combat malnutrition and high child mortality rates in developing countries through zinc supplementation.

ZINC AND THE ENVIRONMENT
Throughout the process of evolution, living organisms have utilized the zinc available in their surroundings for proper development. It is an essential element for the functioning of ecosystems.
Living organisms absorb the zinc they need to survive directly from their environment. Therefore, maintaining a balanced level of this element in nature is crucial for their proper functioning.
