Classification[ edit ] Classically, "lead poisoning" or "lead intoxication" has been defined as exposure to high levels of lead typically associated with severe health effects.
Urine lead levels may be used as well, though less commonly. In cases of chronic exposure lead often sequesters in the highest concentrations first in the bones, then in the kidneys.
If a provider is performing a provocative excretion test, or "chelation challenge", a measurement obtained from urine rather than blood is likely to provide a more accurate representation of total lead burden to a skilled interpreter.
Lead poisoning can cause a variety of symptoms and signs which vary depending on the individual and the duration of lead exposure. Absorption of large amounts of lead over a short time can cause shock insufficient fluid in the circulatory system due to loss of water from the gastrointestinal tract.
A woman who has elevated blood lead levels during pregnancy is at greater risk of a prematurely birth or with a low birth weight. Furthermore, children, especially as they are learning to crawl and walk, are constantly on the floor and therefore more prone to ingesting and inhaling dust that is contaminated with lead.
Although less common, it is possible for fingernails to develop leukonychia striata if exposed to abnormally high lead concentrations. Cardiovascular system[ edit ] Evidence suggests lead exposure is associated with high blood pressureand studies have also found connections between lead exposure and coronary heart diseaseheart rate variabilityand death from stroke, but this evidence is more limited.
Areas of volume loss are shown in color over a template of a normal brain. Occupational exposure[ edit ] Battery recycling workers are at risk for lead exposure. In adults, occupational exposure is the main cause of lead poisoning. Even a small amount of a lead-containing product such as a paint chip or a sip of glaze can contain tens or hundreds of milligrams of lead.
Lead white oil colour was the main white of oil painters until superseded by compounds containing zinc or titanium in the midth century.

Tetraethylleadwhich used to be added to automotive gasoline and still is added to some aviation gasolinescontributed to soil contamination. Residual lead in soil contributes to lead exposure in urban areas.
However, this is not always the case, as there are several other reasons for lead contamination in soil. The city of Madison, Wisconsin addressed the issue and replaced all of their piping, but there are still others that have yet to follow suit.
While there are chemical methods that could help reduce the amount of lead in the water distributed, the sure fix would be replacing the pipes completely. Experts say that if the city were to replace their pipes and the citizens were to keep the old pipes located in their homes, there would be a potential for more lead to flow into their drinking water.Advancing the state of water knowledge and management.
