Blood lead level (BLL), is a measure of the amount of lead in the blood. [1] [2] Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death. [3]
Of North American children, 7% have blood lead levels above 10 μg/dL, whereas among Central and South American children, the percentage is 33–34%. [219] About one fifth of the world's disease burden from lead poisoning occurs in the Western Pacific, and another fifth is in Southeast Asia. [219]
Lead poisoning epidemics refer to specific instances of mass lead poisoning. These events often occur without the knowledge of the communities they affect. Common causes of lead poisoning epidemics include mining, lead recycling, and food/water contamination. [1] These events also cause disproportionate childhood fatalities as children are more ...
Nearly 10,000 local children tested with high lead levels in their blood over the past two decades, and kids are still at risk today. A new law, still a year away from implementation, aims to ...
The problem remains rooted in lower-income communities that have a high percentage of renters and an older housing stock with deteriorating lead paint Children in these NJ communities are most at ...
Lead poisoning is especially hazardous to children under six years of age. [8] High levels of lead at this age can produce impaired neurological development that results in lifelong problems. A 1996 study showed 43% of children ages 1–5 in the Superfund area had blood lead concentrations above the threshold considered dangerous by federal ...
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 ...
Childhood testing for lead poisoning fell steeply at the beginning of the pandemic, and it hasn't rebounded, new data shows. Lead poisoning can cause lifelong harm. Many kids aren't being screened.
