One more environmental pollution that threatens our health through water, but also through the air and skin touch, is hexavalent chromium. It is a compound of chromium, which is dangerously toxic and carcinogenic even in small quantities.

Hexavalent chromium in the environment is almost exclusively derived from human activities as there is not as free formation in nature except in some rare rocks only. It comes from various industrial processes such as steel manufacturing, waste incineration and the color and cement production that emit into the air, water and soil multitude of its compounds.

The World Health Organization, as well as various health and environment agencies around the world, have classified it in the list with the dangerous carcinogens. Experiments that have been done in animals resulted cancer in their vital organs such as the kidneys and digestive organs.

The consumption of contaminated drinking water and food, since through irrigation hexavalent chromium passes in agricultural products, may be damaging to the kidneys, liver and create gastric disorders. Even more there is greater risk by inhalation of droplets and steam as well as by contact with contaminated water, which can cause respiratory problems, lung diseases and even cancer in long-term exposure, allergic and toxic dermatoses.

In our country recently found hexavalent chromium in the water supply of Galia village at Mires, where residents were informed to stop the usage. However conducted investigations in other areas for signs of hexavalent chromium existence in water. This phenomenon isn't unprecedented since in past have been identified in regions of Attica and Viotia, with the larger problem exists in areas bordering the river Asopos.

The solution for a clean drinking water free from hexavalent chromium is Veluda water filters of reverse osmosis. Kapodistrian University testified through its analysis - study that our filters remove hexavalent chromium.
