Poisoning Zinc and its compounds
Occupational Diseases / / August 12, 2017
Zinc - bluish-silver metal is used to produce alloys with non-ferrous metals.
oxide zinc - white crystalline powder, used in the manufacture of glass, ceramics, matches, dental cement, paints, etc.
chloride and sulfate zinc -.. Colorless crystals are used in the pulp and paper industry, for preservingwood, the production of synthetic fibers, zinc paint, tinning and soldering.
MPC for zinc oxide - 6 mg / m3.
In a production environment zinc enters the body mainly through the respiratory system, is released through the gastrointestinal tract, partially - the kidneys.Metallic zinc in the solid and non-toxic dusts.Inhalation of zinc fumes causes the so-called zinc, or metal, fever.
Prolonged exposure may develop zinc oxide is slowly progressive pneumoconiosis (interstitial form).Soluble zinc salts have a significant cauterizing effect on the skin and mucous membranes.
Inhalation poisoning with zinc oxide - a sweet taste in the mouth.After 1-5 h - thirst, tightness and pressin
If poisoning by ingestion soluble salts of zinc: metallic taste in the mouth, burn the mucous membrane of the mouth, digestive tract, persistent vomiting (with blood), abdominal pain, diarrhea, cramps in the calf muscles, the danger of collapse.
Atrophic subatrophic and catarrh of the upper respiratory tract, gastrointestinal disorders.Complaints of fatigue, irritability, sleep disturbances, tinnitus and hearing loss.It may be mild anemia, hypoglycemia, hypocholesterolemia in urine - urobilin and elevated levels of porphyrins.On the X-ray - increased pulmonary pattern, the initial signs of pulmonary fibrosis.It noted an increased incidence of respiratory diseases and digestive system.Perhaps the activation of tuberculosis in the lungs.
are marked ulceration of the skin of the "bird eyes", mainly on the back of the hand, mostly painless.Zinc chloride has a weak sensitizing properties.Allergic dermatitis.
There is evidence of a carcinogenic effect of zinc and its compounds (in the experiment with different ways of introducing fine dust of metallic zinc and zinc chloride in 1.5-2 years the animals developed malignant tumors of various localization).
disability With a significant lesion of the skin can be a temporary disability, often requires a temporary transfer to another job.
