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]
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] High blood lead levels in adults are also associated with decreases in cognitive performance and with psychiatric symptoms such as depression and ...
Elevated lead levels in the blood during pregnancy can increase the risk of miscarriage or premature birth, among other complications. Lead-poisoned adults can experience headaches, abdominal pain ...
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 ...
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 ...
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 ...
Number tested high is defined as a blood lead level greater than or equal to 10 micrograms per deciliter whole blood (μg/dl) See also
