➤ It works as a cofactor of enzymes, provides protection against oxidation, maintains the ionic balance of cellular structures and influences the course of metabolism.

➤ Leads to cephalgia, a characteristic metallic taste in the mouth, gastrointestinal disorders, general weakness, kidney and liver dysfunction.

➤ It has a negative impact on the body's regulatory activity. Causes metabolic and energy balance disorders, leading to anemia and impaired bone marrow function.

➤ OsO4 p-value 1-2%

➤ The substance osmium oxide is widely used for the thorough examination of tissue structures with an electron microscope, as well as in oxidation reactions and modification of the functioning of chemical compounds. .

➤ Osmium tetroxide (OsO₄) - used for dermatoglyphics of fingers and for histological staining of adipose tissues.

➤ The compound osmium tetraoxide Os₃O₄ has a toxic effect on the mucous membranes of the eyes, skin and respiratory tract. A feeling of heartburn and cephalgia is characteristic.

➤ Coughing, abnormal breathing resulting in asphyxiation, decreased visual acuity leading to loss of vision, discoloration and deep burns of the skin, possible blistering, shock and collapse.

➤ Antidote: Dimercaprol.

➤ Free osmium has an odor of chlorine and garlic because it is easily oxidized to OsO₄ anhydride, which has the same odor.

➤ Os is the heaviest of all the elements, with a density of 22.6 g/cm³, and one of the hardest.

➤ Alloys made of Os are the most wear-resistant.

➤ OsO₄ is a catalyst and is used to synthesize the drug cortisone
