Except this molecule isn't dangerous.

>Despite containing both lead and hexavalent chromium, lead chromate is not particularly toxic because of its very low solubility. The LD50 for rats is only 5,000 mg/kg. Lead chromate is treated with great care in its manufacture, the main concerns being dust of the chromate precursor. "Extensive epidemiological investigations have given no indication that the practically insoluble lead chromate pigments have any carcinogenic properties".
- mschuster91 3y agoTo quote just a few sentences afterwards: > One of the greatest threats comes from inhalation of particles, so much effort has been devoted to production of low-dust forms of the pigment. With lead, there is no safety assumption that one can make. Zero. You never know if someone will expose the paint to acid, basic or otherwise corrosive solutions, if a child ingests it, or what happens with it in the human body.
