Lead Chromate, with the chemical formula PbCrO₄, is an inorganic compound recognised for its bright yellow to orange hue. This pigment, often referred to as "chrome yellow," has been widely used historically in paints, coatings, and plastics due to its vivid colour and durability. Lead chromate’s excellent opacity and resistance to weathering make it valuable for industrial applications such as road marking paints and corrosion-resistant coatings.
However, its use has declined in recent years due to health and environmental concerns, as it contains lead and hexavalent chromium, both of which are toxic. As a result, safer alternatives are increasingly being adopted, though lead chromate remains significant in specialised and regulated applications.

Lead Chromate is classified as a hazardous substance due to its potential health and environmental risks. Prolonged or repeated exposure can damage organs (H373). Environmentally, it is extremely toxic to aquatic life, with both acute and long-lasting effects (H400, H410). Proper handling requires precautions to avoid inhalation, skin contact, or environmental release, and it should only be managed by trained professionals using appropriate safety measures.
Make sure to read the Material Safety Data Sheet (MSDS) for all hazard information before handling Lead Chromate.
