Lead may also be harmful to the developing immune system, causing production of excessive inflammatory proteins; this mechanism may mean that lead exposure is a risk factor for asthma in children. [188] Lead exposure has also been associated with a decrease in activity of immune cells such as polymorphonuclear leukocytes. [188]
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]
Exposure to lead in gasoline during childhood resulted in many millions of excess cases of psychiatric disorders over the last 75 years, a new study estimates. Lead was banned from automobile fuel ...
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 ...
However, chronic exposure to metals, “even at low levels, can lead to detrimental health impacts, affecting cardiovascular, renal, cognitive and psychiatric functions,” she added.
Exposure to lead in utero, infancy and early childhood can lead to harmful neurological effects like learning and behavior disabilities and lowered IQ. For adults, chronic lead exposure is linked ...
Lead may be found in food when food is grown in soil that is high in lead, airborne lead contaminates the crops, animals eat lead in their diet, or lead enters the food either from what it was stored or cooked in. [287] Ingestion of lead paint and batteries is also a route of exposure for livestock, which can subsequently affect humans. [288]
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 ...
