Knowra Lead poisoning Lead poisoning Lead poisoning is illness caused by lead accumulating in the body. It can damage the nervous system, blood, kidneys, and other organs, often without obvious early symptoms.
Lead : Lead is a dense, malleable metal with the chemical symbol Pb and atomic number 82. This toxic element accumulates in the body and drives the illness.
Lead paint : Lead paint is paint containing lead compounds, historically used for color, durability, and corrosion resistance. Deteriorating paint and contaminated dust are major exposure sources in older buildings.
Flint water crisis : The Flint water crisis was a public health emergency after contaminated drinking water exposed residents of Flint, Michigan, to lead and other hazards. Corrosion control failures allowed lead from service lines and plumbing to contaminate water.
Childhood lead exposure and cognition : Childhood lead exposure and cognition describes how lead exposure is associated with lower cognitive performance and developmental difficulties. Brain effects can persist after blood lead levels decline.
Acute lead poisoning : Acute lead poisoning is illness caused by a large lead exposure over a short period. It can produce severe symptoms rapidly, unlike the often subtle effects of chronic exposure.
Blood-brain barrier : The blood-brain barrier is a selective interface that regulates which substances pass from blood into brain tissue. Lead can cross this protective interface, particularly in children.
Lead service line : A lead service line is a pipe that carries drinking water from a water main to a building and contains lead. Corrosion can release lead into household drinking water.
Roman lead poisoning : Roman lead poisoning is the proposed contribution of lead exposure to illness in ancient Rome through water systems, cookware, and other uses. The case illustrates historical exposure, though its population-wide effects remain debated.
Lead and cardiovascular disease : Lead and cardiovascular disease concerns associations between lead exposure and elevated blood pressure, cardiovascular disease, and related mortality. Lead's effects extend beyond childhood development to adult cardiovascular health.
Chronic lead poisoning : Chronic lead poisoning is illness resulting from repeated or prolonged lead exposure and accumulation. Long-term exposure can cause progressive organ damage without an obvious initial crisis.
