The symptoms of zinc poisoning by inhalation of zinc oxide fumes are neurological symptoms such as spasticity and confusion, pulse velocity, pharyngeal congestion, and coarse breath sounds in both lungs. Heavy inhalation can be complicated by bronchitis pneumonia and pulmonary edema and respiratory distress hypoxia and hair group, etc. Long-term inhalation of zinc stearate dust can cause pneumoconiosis with cough, sputum, shortness of breath, hemoptysis, chest canker, etc. Poisoning is mostly caused by inhalation of dust containing zinc. It should be the result of a combination of factors such as deposition of dust, involvement of the respiratory system, as well as the patient’s external environment, treatment, etc. Short incubation period, usually 1-8 hours after inhalation, suddenly appear violent chills, lasting 1 or 2 hours after high fever up to 38-40 ℃, can be accompanied by headache, dizziness, weakness, sweating muscle and joint canker tinnitus, similar to the onset of malaria at the same time there are respiratory symptoms, there can also be gastrointestinal tract dysfunction, severe cases have neurological symptoms, such as spasms, delusions and confusion, physical examination can be found in the pulse rate, pharynx The physical examination may reveal rapid pulse, congestion in the throat, rough breath sounds in both lungs, etc.; recurrent attackers may have hepatomegaly, pressure pain, elevated transaminases, anemia, etc. Generally, the fever lasts for 6-7 hours, and the symptoms mostly subside within 24-48 hours. Using flame atomic absorption method, determination of toxic substances (zinc) blood zinc urine zinc higher than normal, increased white blood cells, neutrophils left shift, platelets can be reduced several times, acute attacks can lead to anemia, increased blood glucose urine glucose positive urine bile increased occasionally leaf order urine aminotransferase elevation. Heavy inhalation can be complicated by bronchitis, pneumonia and pulmonary edema and respiratory distress, hypoxia and hair group, etc. Long-term inhalation of zinc stearate dust can cause pneumoconiosis with cough, sputum, shortness of breath, hemoptysis, chest canker, etc.
