Lead Poisoning in Poor Neighborhoods

Scientists using federal grants spread fertilizer made from human and industrial wastes on yards in poor, black neighborhoods to test whether it might protect children from lead poisoning in the soil. Families were assured the sludge was safe and were never told about an harmful ingredients. Nine low-income families in Baltimore row houses agreed to let researchers till the sewage sludge into their yards and plant new grass. In exchange, they were given food coupons as well as the free lawns as part of a study published in 2005 and funded by HUD. No one involved in the $446,231 grant for the two year study would identify the participants, citing privacy concerns. There is no evidence there was ever any medical follow-up. Don't you think that is strange?
