ABLES states are required to have a mandatory state requirement that laboratories report blood lead level results to the state health department or designee. [13] The lowest blood lead level to be reported varies from state to state. Lead may be taken home from the workplace on clothes or in cars potentially exposing spouses and children.
Measuring a person's blood lead level requires a blood sample, which may be performed with a fingerstick or a blood draw.. The amount of lead found in the blood sample may be measured in micrograms of lead per deciliter of blood (μg/dL) especially in the United States; 5 μg/dL is equivalent to 0.24 μmol/L ().
Over 170 million U.S.-born people who were adults in 2015 were exposed to harmful levels of lead as children, a new study estimates. Researchers used blood-lead level, census and leaded gasoline ...
The CDC uses a level of 3.5 micrograms per deciliter to identify kids with higher blood lead levels than most. Lead exposure can cause a large variety of symptoms, Breeher said, including ...
Lead is widely understood to be toxic to multiple organs of the human body, particularly the human brain. Concerns about even low levels of exposure began in the 1970s; in the decades since, scientists have concluded that no safe threshold for lead exposure exists. [2] [3] The major source of lead exposure during the 20th century was leaded ...
The study published Wednesday combined data on blood lead levels and estimates of historical lead exposure with findings from past studies, including a 2019 study of nearly 600 New Zealand ...
Since the 1970s and ‘80s, when lead paint was banned and leaded gasoline phased out, median blood lead levels in the U.S. have declined by 96%, according to estimates in CDC health survey data.
The US Centers for Disease Control and Prevention and the World Health Organization state that a blood lead level of 10 μg/dL or above is a cause for concern; however, lead may impair development and have harmful health effects even at lower levels, and there is no known safe exposure level.
