Lead poisoning is quite common in suburban and urban areas, when houses / buildings are demolished. There's a huge plume of lead and asbestos dust that is generated, even if the contractor is making some effort to wet the site. If a building or home in your area is being demolished? Don't open your windows, and don't go outside without a well-fitting dust mask. Never attend a building demolition event. Contractors and developers are supposed to take measures and inform local government...if they're stupid enough to inspect for lead / asbestos before construction and declare that they're doing asbestos / lead abatement. Every piece of regulation and law I've found uses a very fascinating phrasing - you're required to do things if conducting abatement. Many states go further and exempt anything under a dozen or two units or commercial buildings. It's an absolute shitshow.
