So the US Department of Housing and Urban Development tested laying down sludge on lawns and a vacant lot to see if it reduce lead poisoning. Interesting. Lead poisoning is certainly bad but besides the rather suspicious fact that studying this only in poor black neighbourhoods seems unethical in terms of choosing the people who would have the fewest means to argue, it also seems invalid. What if it turns out that it's fine for African Americans but deadly for Caucasians? What if poorer individuals, due to a less healthy diet, are more sensitive to whatever's in the sludge, as compared to middle and higher income families? I don't know anything about this study other that from the above linked article so perhaps I'm assuming a lot but I would hope that details about other tested areas and populations would be reported by the Associated Press.
