Literature on cadmium poisoning symptoms?

summary

Cadmium poisoning is mainly caused by inhalation of cadmium dust or cadmium compound dust. A large amount of inhalation can cause acute pneumonia and pulmonary edema; Chronic poisoning causes pulmonary fibrosis and kidney disease. The industries that come into contact with cadmium include smelting, spraying, welding and casting bearing surfaces of cadmium, using cadmium rods or graphite rods covered with cadmium as neutron absorbents in nuclear reactors, manufacturing cadmium batteries and other cadmium compounds, etc. Japan reported that "tongtongbing" is a chronic cadmium poisoning caused by long-term ingestion of water polluted by cadmium sulfate.

Literature on cadmium poisoning symptoms?

Most of them are caused by eating acidic food in cadmium plated containers. After several minutes to several hours, they have symptoms similar to acute gastroenteritis: nausea, vomiting, abdominal pain, diarrhea, general fatigue, muscle soreness, headache and muscle pain. They can collapse due to water loss, and even die of acute renal failure. The lethal dose of cadmium in adults is more than 300 mg.

Inhalation of high concentration of cadmium smoke caused by the first symptoms of upper respiratory tract mucosa irritation, the above symptoms were relieved after contact. After 4-10 hours incubation period, cough, chest tightness, dyspnea, chills, back and limbs muscle and joint pain, chest X-ray examination showed patchy shadow and lung texture thickening. Severe patients with delayed pulmonary edema may die of respiratory and circulatory failure. A few patients had liver and kidney damage. In a few cases, pulmonary fibrosis occurred after acute phase, leading to pulmonary ventilation dysfunction.

Long term excessive exposure to cadmium mainly causes kidney damage, and a few severe advanced patients may have bone lesions. Inhalation poisoning can also cause lung damage. Patients with chronic poisoning are often accompanied by macula in the neck of teeth, loss or anosmia, nasal mucosa ulceration and atrophy, mild anemia, occasional anorexia, nausea, mild abnormal liver function, weight loss and hypertension. Lung cancer incidence rate increased after long-term exposure to cadmium.

matters needing attention

First aid treatment of oral poisoning, as soon as possible with warm water gastric lavage, catharsis, and rehydration, correct water, electrolyte disorders; Acute inhalation poisoning should be evacuated early, stay quiet, stay in bed, breathe in oxygen, keep airway clear, use 10% silicone inhalation to eliminate foam, adrenal cortex hormone can reduce capillary permeability, early appropriate use.
