What Are The Advantages And Disadvantages Of Lead?

(Campbell, 2016). Two giants in childhood lead poisoning research and advocacy, Dr. Philip Landrigan and Dr. David Bellinger, summarize the adverse effects of lead very completely, yet succinctly: “Lead is a devastating poison. It damages children’s brains, erodes intelligence, diminishes creativity and the ability to weigh consequences and make good decisions, impairs language skills, shortens attention span, and predisposes to hyperactive and aggressive behavior. Lead exposure in early childhood is linked to later increased risk for dyslexia and school failure.”(p. 3).

The author further goes on to explain what is being done about lead poisoning, and finally explaining how to know for sure if a person has lead poisoning and how to have your home tested for lead poisoning. The author pays great attention to detail by providing facts to support the information provided in the article. For example, the author states, "75% of houses and other buildings built before 1978 have lead-based paint. When the paint is in good condition it does not pose a threat. When it chips and peels however, it can make a child very ill" (Heck, Where does lead come from section, para. 1). This article clearly achieves its purpose, which is to inform the public about prevalence of lead and the ongoing risks associated with lead poisoning. This article is not about one specific case of lead poisoning, which is evident because the author talks about the history of lead use and the laws relating to lead use in this country.

What are some of the effects of the crisis? For any adult, lead poisoning can cause kidney problems, fatigue, lethargy, depression, and slower reaction time. However, adults require a higher level of lead in the blood to produce those effects. For pregnant women lead poisoning can can cause miscarriages and future health problems in a developing fetus. What about children? For children, lead poisoning affects the development of children's brains and nervous systems.

Everyone is susceptible to the dangers of lead contamination; but children are especially at risk. High levels of lead in children can lead to brain and kidney damage and damage to red blood cells. Low levels of lead can also cause problems that are less life-threatening but can be just as devastating, like low IQ, hearing and language impairment, reduced attention span and poor school performance. In adults, exposure to lead can lead to an increased risk for high blood pressure. Pregnant women and their fetuses are extremely vulnerable to lead. In women, lead increases the risk of infertility and miscarriages; in fetuses, lead can cause low birth weight, premature birth and impaired mental and physical development.

1900s, it may also be the case that the exposure of lead is also an important factor that affected

The water in Flint is placing people in peril because the water is accumulating with lead. Lead is a type of chemical element in the carbon group. Lead is a soft and heavy post - transition metal. If lead accumulates in your body you could sustain death or lead poisoning. Lead poisoning occurs when lead builds up in the body often over a period of months or years. Even small amounts of lead can cause perpetual health problem. Children under the age of six are vulnerable to lead poisoning and possibility death.

Children under six years old are very easily affected to the effects of lead. Even low levels of lead in the blood of children can result in: behavior and learning problems, lower IQ and hyperactivity, slowed growth, hearing Problems and anemia; lead can accumulate in our bodies over time, where it is stored in bones along with calcium. For pregnant women, during pregnancy, lead is released from bones as maternal calcium and is used to help form the bones of the fetus. This is particularly true if a woman does not have enough dietary calcium. Lead can also cross the placental barrier exposing the fetus the lead. So lead can cause serious effects to the mother and her developing fetus, including: reduced growth of the fetus and premature birth. And for other adults, lead can also be harmful, it can cause cardiovascular effects, increased blood pressure and incidence of hypertension, decreased kidney function, and reproductive problems in both men and

Lead is poisonous because once it enters your body it can form into other atoms like zinc and iron fooling the body into thinking they are there and not carrying out the vital functions they need. Lead atoms can also block neurotransmitters. In the 1920s there was essentially a lead "boom" and marketers began putting lead in everything including shoes, lightbulbs, and leaded gasoline, advertising that it was safe and even kid friendly (in some items) when it wasn't. The lead levels in the factories became so bad that the workers were becoming sick, hallucinating, going mad, and dying from being poisoned by lead. Scientist Robert Kehoe was hired by GM to "cover up" the lead threats saying the amount of lead was a naturally occurring. No one cared about the use of leaded gasoline and other leaded materials until Clair Patterson began to dig deeper into the research of lead in the

Lead is a poisonous substance when consumed by humans, and can cause behavioral problems, learning disabilities, and kidney illnesses, among other complications. Corrosive, inadequately treated water from the Flint River had triggered the lead's release from old pipes in homes and schools. As the extent of the problem became apparent, many residents accused local and state officials of having failed to act early enough to alert the public to the poison, despite civilian complaints that their water smelled, looked, and tasted unusual.

The effects of prolonged exposure to lead will result in lead poisoning. It causes behavior problems, hearing problems, kidney damage, and slowed body growth (Heller).

When lead enters the human body, it is distributed to the brain, liver, kidney and bones. It is deposited in the teeth and bones where it accumulates over time. Exposure to high levels of lead may cause anemia, kidney and brain damage. Lead exposure can also cause miscarriage and infertility. The effects are even more severe in children. Lead can affect children’s brain development resulting in decreased intelligence quotient (IQ), shortened attention span and increased antisocial behaviour. At high levels of exposure, lead may attack the brain and central nervous system, causing coma. Children who survive severe lead poisoning may continue to suffer mental retardation and behavioural disorders. Furthermore, pregnant woman exposed to lead can

Chronic lead poisoning in children may cause intellectual disability, seizure disorders, aggressive behavior disorders, developmental regression, chronic abdominal pain, and

Health officials agree that no amount of exposure to lead is safe, be it from water, the air, old paint, or dirt. Even the smallest of amounts can lead to irreversible cognitive and developmental damage, especially in younger children.

Lead dust is dangerous to everyone because lead dust is so small it cannot be seen with the human eye (Ways to Reduce Lead Dust in Your Home or Apartment). Unsanitary shooting ranges around the United States leave toxins, such as lead dust and vapor, in the air and tables with lead on it (Ways to Reduce Lead Dust in Your Home or Apartment). A lack of air purification and circulation keeps contaminated air inside the facilities. Contact with lead can easily spread to homes and the outside world. Therefore, this leads to deadly consequences because lead dust cannot be seen and of the amount for a lethal dosage. The U.S. government needs to increase regulations and laws about the health and safety environment of recreational shooting ranges.

Lead, a naturally occurring metal and can be used in almost everything. It can cause serious health issues if it is exposed for a long time, particularly in children as they are more susceptible to absorbing and retaining lead in their bodies. Each year, in the United States 310,000 of 1- to 5-year age group are found to have unsafe levels of lead in their blood, which can cause a wide range of symptoms. (1)
