“Despite the limited evidence for lead chromate causing cancer in humans, there is ample evidence in humans and animals that all Cr(VI) compounds, both soluble and insoluble, are capable of causing lung cancer.” Lead poisoning can occur in exposed workers.

In 1977 the Consumer Product Safety Commission banned "lead containing paint" prohibiting the use of such paint on products to which consumers are exposed after sale. [ATSDR ToxFAQs, Toxicological Profile, Regulations and Advisories]
