Lead carbonate, PbCO3, is a mineral composed of orthorhombic crystals. It decomposes at about 315degC, producing toxic fumes and reacting violently with fluorine to produce a fire hazard.
Lead is a toxic metal and can cause severe health problems, including comas or death in children. It is also thought to cause hearing loss and IQ problems in children.
Water soluble leads include lead(II) acetate, lead(II) carbonate, and lead metaborate (Pb(CO3)22-). These are important industrial chemicals used in the production of colored glazes, white house paints, and tin-lead plating applications.
Various sets of batch dissolution experiments have been conducted to investigate the impact of pH values ranging from 7.0 – 9.5, temperatures (5@C vs. 20@C) and alkalinity levels (moderate vs. low) on the solubility of lead species in drinking water.
The results of these experiments have shown that pH ranging from 7.0 to 9.5 has no significant influence on the dissolution of lead species. In addition, cold temperature and moderate alkalinity showed a great influence on decreasing the solubility of lead species.
Inhalation of lead carbonate can lead to a variety of health problems such as respiratory tract irritation, sore throat, and lead lines in the gums. Exposure to lead can also be a serious health risk for pregnant women. It can have long-term effects such as lowered IQ, behavioral disorders, and seizures.
