Lead is a naturally occurring metal. It is used in industry and, in the past, was added to petrol and household paints.
Lead is not required for human health and can be hazardous when taken into the body by swallowing or breathing in lead or materials contaminated with lead. Once in the body, lead circulates in the blood and can be stored in the bones. Young children, including unborn babies, are at greatest risk of the health effects of lead exposure.
Children are most often exposed to lead by swallowing items or soil containing lead or breathing in dust containing lead.
Adults are most often exposed to lead if they work in a job which involves lead-based activities. In Australia the most common source of lead exposure is at workplaces involving the use of lead compounds.
Workers can also sometimes bring lead residues into their home on their work clothes, skin, hair and equipment after contact with lead. The Department of Health and Human Services Victoria Environment Section can provide advice about lead sources in the home and how to manage them safely Tel.
Lead exposure can permanently damage the brain and impair intellectual development. For children the risk of exposure to lead and the health effects of exposure can depend on their environment, stage of development or behaviours.
Children under five years of age are especially vulnerable to lead exposure because:. Children with pica — a behaviour that leads to eating non-food substances such as peeling paint flakes, soil or small objects — are also at an increased risk of lead exposure.
Children are particularly at risk during home redecorating or renovating, as they may pick up or swallow paint chips or dust. Unborn babies are also at risk, since lead swallowed by the pregnant mother readily passes through the placenta.
Breastfeeding mothers can also pass on lead to their infants via their breast milk. Lead exposure can affect people differently, and symptoms often depend on the type of exposure. Some children or adults may not have any symptoms at all. Acute lead poisoning is usually caused by a recent exposure to a high amount of lead.
The symptoms may include:. If a person is exposed to smaller amounts of lead over a longer time period, chronic long-term or ongoing lead exposure may produce symptoms such as:. Many of these symptoms could be caused by other conditions, so it is important to see a doctor if you are worried. If you suspect that you or a member of your family has been exposed to lead, visit your doctor for further advice.
They may recommend that you have a blood test to measure the amount of lead in your blood and determine whether you have been exposed to lead. Your doctor or paediatrician can advise you about avoiding exposure to lead. They may recommend monitoring your blood lead level s to assess the effectiveness of any action taken. If your blood lead levels are extremely high your doctor may recommend a treatment known as chelation therapy to rapidly decrease the amount of lead in your body.
Someone from the department may contact you to help you understand the source of your lead exposure. This will help prevent further lead exposure to you and the people around you. If you think you or someone else may be in a situation where you are exposed to lead at home or work, you can reduce this exposure by:.

Adult lead paint poisoning symptoms. What Is It?
It is stored in the organs, tissues, bones and teeth. The leading source of exposure to lead is lead-based paint. This was outlawed for residential use in But it remains in some older homes.
The main hazard is paint dust. Paint dust enters the air when old paint is scraped, sanded or begins to flake. Children face the most serious risk. Their growing bodies absorb more lead. Young children, especially toddlers, tend to put objects in their mouths that may be covered with lead dust.
If lead paint is flaking, small children sometimes eat the sweet tasting paint chips. Or they chew on painted surfaces, such as window sills.
Adults who have high lead levels in their blood usually were exposed in the workplace. Industries with a high potential for exposure include:.
Construction that involves welding, cutting, blasting or other disturbances of surfaces painted with lead. Young children can be exposed to lead when parents who work in these areas carry lead dust home on their clothes and shoes.
A woman who had lead poisoning can pass lead on to her fetus if she becomes pregnant. This remains true even if she no longer is exposed to lead. Since lead was banned in gasoline and residential paint, average blood levels of lead have dropped dramatically in the United States. Recent studies suggest that even lower levels may be harmful. They are encouraged to look carefully for possible sources of lead exposure. The damage may not be obvious. It only becomes noticeable at school age, when the child shows signs of possible learning disabilities, behavioral problems or mental retardation.
A doctor who thinks someone has lead poisoning will do a physical examination. He or she will ask about:. Blood tests can also be used for lead screening. Because there are often no early symptoms, a blood test is the best way to identify children at risk of lead poisoning at an early stage. Lead screening typically starts at age 6 months to 12 months.
Lead screening guidelines vary from state to state, but the minimum screening is at 1 and 2 years. Live in or regularly visit a house built before that has been remodeled in the last six months. Live near an active smelter, battery recycling plant or other industry likely to release lead into the air. It may take several weeks, months or years for lead to leave the body, even after there is no further exposure.
To prevent lead poisoning, avoid or minimize exposure to lead. Remove lead paint or contain it with frequent cleaning:. Use a mop or sponge with warm water and an all-purpose cleaner to regularly clean floors and other surfaces. If you have lead paint in your home, do not try to remove it or paint over it yourself. Improper removal of lead paint can make contamination worse by sending lead-containing dust into the air. If you have lead pipes or lead solder in your plumbing, or if you have an older house and are not sure about the pipes, call your local health department or water supplier for information on getting your water tested.
Run the water for 15 seconds to 30 seconds before drinking it, especially if you have not used the water from that faucet for a few hours. Insist that your employer comply with all federal and state laws to protect workers and to monitor their health. Launder your work clothes separately from those of the rest of the family or from clothes you do not wear for work.
For more information on sources of lead poisoning and ways to prevent them, visit the Lead website at the Centers for Disease Control, www. For all cases of lead exposure, the most important step is to remove the source of lead. However, repeat blood tests to be sure the amount of lead in the bloodstream stays low. Higher levels of lead in the bloodstream may need to be treated.
Treatment consists of taking a drug that binds to the lead and helps the body to remove it. This process is called chelation therapy. Doctors decide whether to use chelation therapy on a case-by-case basis.
Blood tests help track blood levels until they are no longer too high. Besides recommending a nutritious diet, the doctor also may recommend iron or calcium supplements. If a child with lead poisoning has iron-deficiency anemia, it is very important that the anemia be treated. Anemia puts the child at higher risk. It was a significant cause of mortality amongst slaves and sailors in the colonial West Indies.
With the Industrial Revolution in the 19th century, lead poisoning became common in the work setting. The 20th century saw an increase in worldwide lead exposure levels due to the increased widespread use of the metal.
The levels found today in most people are orders of magnitude greater than those of pre-industrial society. In the late s through the s Herbert Needleman and Clair Cameron Patterson did research trying to prove lead's toxicity to humans. ConAgra Grocery Products Company et al. The Plaintiff shall recover its costs on appeal. Studies have found a weak link between lead from leaded gasoline and crime rates.
Humans are not alone in suffering from lead's effects; plants and animals are also affected by lead toxicity to varying degrees depending on species. Farm animals such as cows and horses  as well as pet animals are also susceptible to the effects of lead toxicity. Lead, one of the leading causes of toxicity in waterfowl, has been known to cause die-offs of wild bird populations.
The critically endangered California condor has also been affected by lead poisoning. As scavengers , condors eat carcasses of game that have been shot but not retrieved, and with them the fragments from lead bullets; this increases their lead levels.

The Weight of Lead: Effects Add Up In Adults
Lead toxicity is not a problem of the past, nor is it the exclusive domain of children. In fact, lead continues today to pose a serious threat to the health of many U.
But there are still pockets of high exposures, such as among workers in certain industries. Industries most affected include lead mining, refining, and smelting; construction work involving paint removal, demolition, and maintenance of outdoor metal structures such as bridges and water towers; auto repair; and battery manufacturing and recycling.
When workplaces adhere to the OSHA standard, occupational exposures are usually reduced below levels that cause symptomatic lead poisoning. But as far back as , studies have suggested that significant health effects happen at levels below those allowed by OSHA.
Now scientists say the evidence is overwhelming that action needs to be taken to further reduce lead exposures in both the workplace and the general environment. The most recent evidence from epidemiological and toxicological studies suggests that low levels of exposure can, over time, damage the heart, kidneys, and brain. Some of these health effects, such as a 1-mm rise in blood pressure or a slight cognitive decline, seem small when expressed as the average impact to the entire population.
In one individual, they may not even be noticed. But the overall impact on public health nevertheless worries scientists. Tests to measure lead exposure itself and its health effects have become more sophisticated.
For example, similar blood lead concentrations in two individuals or populations do not necessarily translate to similar exposure histories. For instance, lead will mobilize from bone more quickly in people with conditions in which the body is resorbing bone, such as pregnancy or osteoporosis. Stores of lead in bone are a more reliable marker of cumulative lead exposure. In the late s a noninvasive way of measuring bone lead emerged, using X-ray fluorescence technology.
Scientists began applying the technique in epidemiological studies in the s. Studies of cognitive function, for example, now have the benefit of more sensitive markers, including tests of memory, visuospatial function, and the ability to communicate or understand communication.
In addition, studies with larger sample sizes and those that look at community-based populations, not just occupationally exposed workers, have sharpened the picture of the effects. But animal studies support many of these findings and suggest mechanisms for some of these health effects. A large number of these studies have investigated the effects of lead on blood pressure.
Increases in both blood lead and bone lead appear to be associated with blood pressure increases. Many epidemiological studies in humans suggest that rising blood lead correlates with rising blood pressure. In the last 15 years, about a dozen studies have also tied bone lead to blood pressure increases.
For example, in a longitudinal study published in the 15 January American Journal of Epidemiology , Yawen Cheng of Harvard Medical School and colleagues found that in men who began the study without hypertension, baseline bone lead level predicted development of the condition six years later. Rothenberg points out that although blood lead primarily reflects recent exposures, it can also in part reflect the leaching of bone lead stores back into the bloodstream.
Lead is also associated with increased mortality from diseases of the heart. So, how does lead actually cause cardiovascular effects? Animal studies show that lead can promote the growth of vascular smooth cells, which play a role in the formation of atherosclerotic plaques. Oxidative stress happens when chemically reactive oxygen and nitrogen damage cells in a process similar to how oxygen rusts metal.
Damage from lead-induced oxidative stress has been demonstrated in studies of rats as well as in studies of human cells in culture, says N. But in animals it takes 10 to 12 weeks for lead exposure to result in hypertension, and in humans it likely takes years to decades, Vaziri says. One possible reason is that the body launches a variety of defense mechanisms that prevent or minimize rapid rise in blood pressure and gross tissue damage. However, over time, these defense mechanisms gradually fail, blood pressure begins to rise, and detectable tissue damage appears.
Vaziri demonstrated this progression in cell culture studies published in the May issue of the American Journal of Hypertension. So we had a reduction in superoxide at an interim period. But the defending enzyme converts superoxide to hydrogen peroxide, which is less toxic than the original free radical but still toxic, and capable of causing injury and dysfunction upon prolonged exposure. Ultimately, however, lead exhausts the system. Epidemiological studies of the general population suggest that kidney function may be altered at the lowest levels of blood lead studied to date in relation to renal effects.
In a review published in the December 2 issue of Kidney International , E. This is because the kidneys help regulate blood volume and vascular tone, which are the principal determinants of blood pressure. Thus, alterations of kidney function or structure can cause the blood vessels to constrict throughout the body, thereby raising blood pressure.
Declines in cognitive function are more likely to be associated with lower-level environmental exposures over time, rather than recent acute exposures. In the May issue of EHP , Lourdes Schnaas of the Mexican National Institute of Perinatology and colleagues published one of the few studies of this relationship to pinpoint prenatal lead exposure as a greater risk to offspring IQ than childhood exposure.
Previous studies had shown the strongest effects with postnatal exposure. In the EHP study, though, prenatal exposure had a more significant effect than postnatal exposure, and the strongest effects were seen at the lowest levels of exposure, says Rothenberg, a coauthor on the study. In other neurotoxic effects, animal studies have suggested that lead exposure increases the risk of brain cancer. Some association studies in humans also have suggested a link.
For instance, a 1 September report in the International Journal of Cancer by Edwin van Wijngaarden, an assistant professor of community and preventive medicine at the University of Rochester, showed that workers in jobs with high lead exposure were more likely than unexposed subjects to die from brain cancer. Wijngaarden is now recruiting participants for a pilot study in which he will measure bone lead in patients with brain tumors.
No studies to date have measured bone lead in cancer patients. Despite these findings, however, studies of brain cancer and lead have been inconsistent—some studies have found elevated rates of brain cancer associated with lead exposure, and some have not. For cancer in general, most studies show a positive association between low levels of lead exposure and cancer, but with relatively few cancer deaths, says Kyle Steenland, a professor of environmental and occupational health at Emory University.
Some scientists say that determining a threshold would require long-term prospective studies of adults with blood lead levels commonly found in the current population. Scientists disagree on just how low measurements need to go. Further, policy makers will want to know if there is a level of blood lead below which the resulting improvement in public health no longer outweighs the cost of further exposure reduction.
Still, the group could have had higher exposures before Physicians can get some idea of cumulative exposure by measuring blood lead regularly. Scientists have been calling for reductions in these cutoffs as far back as Indeed, a Supreme Court decision in the case of Automobile Workers v.
Johnson Controls held that precluding such women from exposure would be unlawfully discriminatory. In the past, OSHA has touted its emphasis on voluntary medical surveillance programs and other measures to reduce exposure.
Industry tends to favor voluntary exposure reduction as well. Other subgroups that are very susceptible to lead exposure are emerging, and scientists say these groups pose another reason that regulations should be strengthened. People with certain genetic susceptibilities might constitute one such group. Now, scientists are finding that the same is true of the emergence of health effects at very low levels of lead exposure, and recent research suggests that genetic variations may play a role.
People who already have medical conditions are also at increased risk. In the November issue of EHP , Hu and colleagues showed that lead exposure was associated with increased heart rate variability an indicator of poor cardiovascular health , especially in people with metabolic syndrome, a cluster of conditions including obesity, high blood sugar, and high blood pressure.
Such studies point to another reason why lead exposure is very much a problem of the present. He points out that although blood lead levels have decreased substantially in the last 30 years, they are still much higher than they were in preindustrial times, before humans began spreading lead into the air, water, and soil. Increases in both bone lead and blood lead appear to be associated with possibly dangerous increases in blood pressure.
Studies show that higher blood lead concentrations are linked to decreases in kidney function. Lead exposure is known to cause declines in brain function, but the link to brain cancers is less clear. Measurements of lead in the body are taken from blood and bone, but each has limitations.
More accurate methods are needed, particularly to measure effects of low-level exposures. National Center for Biotechnology Information , U. Journal List Environ Health Perspect v.
