Disclaimer and references

Lead (II) sulfate (sulphate in British English) (PbSO4) is a white crystal or powder. It is also known as white lead, fast white, milk white, sulphuric acid lead salt or anglistlite.

It is often seen in at the terminals of car batteries, as it is formed as the battery is discharged (and electrolysed back to lead and sulfuric acid when the battery is recharged). This compound is insoluble.

[edit] Toxicology

Lead sulfate is toxic by inhalation, ingestion and skin contact. It is a cumulative poison, and repeated exposure may lead to anemia, kidney damage, eyesight damage or damage to the central nervous system (especially in children). Some lead salts may cause reproductive defects and cardiovascular disturbances. It is also corrosive - contact with the eyes can lead to severe irritation or burns. Typical threshold limit value (above which the substance is harmful) is 0.15 mg/m³.

[edit] Mineral

The naturally occurring mineral anglesite, PbSO4, occurs as an oxidation product of primary lead sulfide ore, galena.
