If you take the average American and analyze their lead content what do you find?  Do you find that its been decreasing? - You find the lead content of about two micrograms per deciliter we will call it two units and the average was much higher lets say 20 30 years ago, 20 30 years ago they tested when they the CDC they found in some cities 80 85 percent of the children had lead in their blood of 20, 20 30 units and today that is considered to be lead poising in those days the CDC threshold level up near 60, 70 80 and it took decades before they started reducing it, now they are down to 10 units as the threshold level for lead toxicity, but the fact of the matter is from a scientific standpoint there is no threshold, there really isn't. We have evidence, solid evidence that a blood like concentration of core blood in the fetus for example of one microgram per deciliter which is we call it one unit to compare it to the threshold the CDC threshold of 10 units that will already cause a decrease in IQ of a child of about seven points.
