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.

Short-Term Effects

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 Lead white oil colour was the main white of oil painters until superseded by compounds containing zinc or titanium in the midth century.

It is speculated that the painter Caravaggio and possibly Francisco Goya and Vincent Van Gogh had lead poisoning due to overexposure or carelessness when handling this colour. 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.

The ultimate goal is for a total overhaul to take place, but this would require the citizens to buy into the pipe replacement. Such a move would allow the preservation of present health and secure greater health for the future.

Ceramic glaze often contains lead, and dishes that have been improperly fired can leach the metal into food, potentially causing severe poisoning. Bullets[ edit ] Contact with ammunition is a source of lead exposure. As oflead-based ammunition production is the second largest annual use of lead in the US, accounting for over 84, metric tons consumed in Because game animals can be shot using lead bullets, the potential for lead ingestion from game meat consumption has been studied clinically and epidemiologically.

In a recent study conducted by the CDC, [] a cohort from North Dakota was enrolled and asked to self-report historical consumption of game meat, and participation in other activities that could cause lead exposure. The study found that participants' age, sex, housing age, current hobbies with potential for lead exposure, and game consumption were all associated with blood lead level PbB.

According to a study published in1. However, the biggest impediment to using the vast majority of alternatives relates to current laws in the United States pertaining to armor-piercing rounds. Laws and regulations relating to armor-piercing ammunition expressly prohibit the use of brass, bronze, steel, tungsten, and nearly every metallic alternative in any bullet that can be shot by a handgun, which at this time is nearly every caliber smaller than 50BMG including the popular.

Some lead-based bullets are resistant to fragmentation, offering hunters the ability to clean game animals with negligible risk of including lead fragments in prepared meat. Other bullets are prone to fragmentation and exacerbate the risk of lead ingestion from prepared meat. In practice, use of a non-fragmenting bullet and proper cleaning of the game animal's wound can eliminate the risk of lead ingestion from eating game; [] however, isolating such practice to experimentally determine its association with blood lead levels in study is difficult.

Bismuth is an element used as a lead-replacement for shotgun pellets used in waterfowl hunting although shotshells made from bismuth are nearly ten times the cost of lead.

Pathophysiology[ edit ] Tetraethylleadstill used as an additive in some fuels, can be absorbed through the skin. Lead may be taken in through direct contact with mouth, nose, and eyes mucous membranesand through breaks in the skin.

Tetraethylleadwhich was a gasoline additive and is still used in fuels such as aviation fuel, passes through the skin; however inorganic lead found in paint, food, and most lead-containing consumer products is only minimally absorbed through the skin.Antioxidants and Related Phytochemicals: Current Scientific Perspective Stephen Barrett, M.D.

Many "antioxidant" products are marketed with claims that, by blocking the action free radicals, they can help prevent heart disease, cancer, and various other conditions associated with aging.

Smoking tobacco is a well-known health hazard, which often leads to respiratory and cardiovascular diseases.

However, smoking can impair physical fitness long before these chronic diseases arise.
