With lead it's all about how "bioavailable" it is. The mining companies fought back against the EPA in the 1980s and 90s by feeding mine waste to pigs and then doing necropsies to determine how and what was damaged by the ingested lead (I was directly involved in this "war" as an EPA contractor". It was fun to watch the bureaucrats fold and run when this data was presented.) That data was developed by using hard and sound science and has kept EPA well at bay until now. Lead has many forms, carbides, sulphides, metallic, etc. The science I have seen so far that supports any sort of ban is pure rubbish. Lead dust in the air can be a problem, metallic lead pellets randomly spread around the soils and muddy bottoms of various lakes and rivers is not, period. What I have seen presented so-far is purely emotional speculation, hype and fear-mongering.
