Tin (188,7 а.е.м.) – tracer element, potentially toxic. Tin is containing in gastrin (gastric enzyme), affecting the activity of flavin enzymes, able to increase growth processes. Metallic tin and alloys thereof are widely used in household (tin cans, cans, food containers, foil) Non-organic compounds of tin are hardly-soluble, hardly absorbed and weakly toxic, but in high concentrations could cause inflammation of gastric mucosa. Chronic inhalation of metallic tin-containing dust causes lungs diseases.

Organic compounds of tin could be very toxic. They are present in polyvinyl plastic, elastic paints, fungicides, insecticides, anthelmintic agents. Tin intoxication causes headaches, muscular weakness, fatigue, giddiness, sense of smell disorders and hyperglycaemia.

In severe cases – kidney, eyes, immune and cerebrospinal system diseases. Very long-lasting intoxication with tin dust could cause pneumoconiosis. Increased concentration of tin in hair could indicate constant or past increased level of tin intake.
