Our Chicago personal injury attorneys have long since known of the dangers that lead poisoning can cause to individuals, and children in particular. Nevertheless, the U.S. Centers for Disease Control and Prevention (CDC) recently reduced its threshold level for defining the amount of lead in the blood stream that is sufficient to be classified as lead poisoning in children. According to MSNBC, this is the first such reduction in 20 years.
The CDC released a statement claiming that “the recommendation was based on a growing number of scientific studies showing that even low blood lead levels can cause lifelong health effects.” This new “reference value” for lead poisoning was based on the population of U.S. children aged 1 to 5 years whose blood lead levels are in the highest 2.5 percent of children tested, said the CDC. The newly established base level for defining lead poisoning is 5 micrograms per deciliter of blood, as opposed to the previous standard of 10.
The CDC’s level-adjustment means that more children are classified as having lead poisoning under the new benchmark; approximately 450,000 U.S. children aged 1 to 5 have blood lead levels above the new standard, up from 250,000 with lead levels greater than 10 micrograms per deciliter of blood under the previous threshold, said MSNBC.
