Symptoms of tin poisoning

summary

Tin smelting workers work in the environment of tin dust concentration of 9.362mg/m3, and tin pneumoconiosis occurs. Clinically, cough, expectoration, chest tightness and other symptoms are rare, and most patients have no lung function changes. The chest X-ray film typically showed clusters of round or quasi round small spot like shadows widely distributed in the two lung fields, which looked like petaled Osmanthus fragrans flowers, but did not fuse with each other. Its diameter could reach 3-5mm, with high density and sharp edge. The hilum of lung is usually not enlarged. Symptoms of tin poisoning? Let's talk about it

Symptoms of tin poisoning

It is reported that the lowest concentration of tin in canned food and fruit is 5 mg / kg. It was also reported that eating tinned fruit with the concentration of 563mg / kg or 400mg / kg of tin pollution would lead to nausea, vomiting, diarrhea and other symptoms of acute gastroenteritis. It should be differentiated from acute bacterial gastroenteritis and given symptomatic support treatment.

Most of the lung markings could not be identified or only faintly visible. Ten to 15 years after the diagnosis, the speckled shadows on both sides of the lung field gradually became smaller, the density decreased, the number also decreased, the lung field gradually became clear, but the hilar density gradually increased. After 25-30 years, there were various metal massive shadows in the hilum, but the lung field was clear.

Workers exposed to stannic chloride for a long time may have respiratory tract irritation and digestive tract symptoms, such as nausea, epigastric discomfort, constipation, and sometimes shoulder and foot pain. Stannic chloride can also cause skin ulceration and eczema.

matters needing attention

Tin smelting, crushing and other processes should be mechanized and closed, and ventilation and dust discharge should be strengthened. Besides strengthening personal protection, workers exposed to tin dust should be monitored regularly. For organotin poisoning, we should try to avoid contact with organotin preparations and pay attention to ventilation in the relevant working environment.
