According to the MedLinePlus database of the U.S. National library of medicine, less than 10 micrograms per deciliter (dL) of lead in the blood is considered normal for adults. Furthermore, less than 5 micrograms/dL of lead in the blood is considered normal for children according the the aforementioned database. Therefore, it is my newly held belief that this new restriction is made and that low-income families are protected from unacceptable levels of lead within the paint of the homes that they are planning on purchasing, or have already purchased (that were made prior to 1978).
