How harmful are the used lead-acid batteries? Harmful substances in the processing of lead-acid batteries include lead, sulfuric acid, carbon black, sulfur, and pitch. Among them, the people exposed to lead and sulfuric acid are the most, and these two substances are also very harmful to operators. my country has now included lead poisoning, carbon black pneumoconiosis, and tooth erosion on the list of statutory occupational diseases. 1. The entry route of lead and the entry route of harming lead and its compounds are mainly the respiratory tract, followed by the digestive tract, which cannot be absorbed by intact skin. 2. Sulfuric acid intrusion route and hazards Sulfuric acid is an intrusion route. The most important thing is that sulfuric acid mist is inhaled from the respiratory tract, causing damage to the operator's teeth and upper respiratory fatigue. Currently included in the list of statutory occupational diseases is tooth erosion. Although the geo-sensitivity inflammation of the respiratory tract is not included in the statutory occupational diseases, it should also be concerned. 3. Invasion route and harm of carbon black and pitch Carbon black mainly causes harm to the human body through the respiratory tract and skin. Long-term inhalation of carbon black by the human body will cause fibrotic lesions in the lungs, which will gradually harden the lung tissues and lose normal respiratory function, resulting in pneumoconiosis caused by carbon black.
