I was reading a Slate article about lead in children’s toys. In it, it says that lead paint is still commonly used for road markings and bridges.
Is this really true? Is this source of lead harmful to human health?
Those road markings and painted bridges eventually get degraded and the paint gets pulverized to dust. I would think that this would spread lead over a wide area and anyone in the vicinity would be at a great risk of lead poisoning, even those in cars. I ride my bicycle for thousands of kilometres each year on the road and this would really concern me if it could harm me.
What is the straight dope?
