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]
Elevated blood lead levels (BLLs) in adults can damage the nervous, hematologic, reproductive, renal, cardiovascular, and gastrointestinal systems.. Current research continues to find harmful effects in adults at BLLs previously considered harmless, such as decreased renal function associated with BLLs at 5 micrograms per deciliter (μg/dL) and lower, and increased risk of hypertension and ...
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 US Food and Drug Administration has proposed setting lead levels in baby food of 10 parts per billion for many products and 20 parts per billion for cereals and root vegetables, which can ...
The Food and Drug Administration followed up with a warning against 17 ground cinnamon products found to contain high levels of lead. Short-term exposure to very low levels of lead may not result ...
Anything above that can indicate that lead levels may be unsafe for children, according to the Mayo Clinic. For adults, less than 10 µg/dL is considered normal. A simple blood test can detect the ...
Between the blood lead levels of 5 and 35 μg/dL, an IQ decrease of 2–4 points for each μg/dL increase is reported in children. [42] However, studies that show associations between low-level lead exposure and health effects in children may be affected by confounding and overestimate the effects of low-level lead exposure. [83]
the guidelines, titled "Action Levels for Lead in Processed Food Intended for Babies and Young Children: Guidance for Industry," it added, is the latest move to support its Closer to Zero ...
