The effects of lead on children's brains Essay

The lead in the environment is formed naturally in the earth’s crust mainly as Lead Sulphide. The main exposure channels of lead entering the environment through atmospheric lead is predominantly from automobile emissions. Other lead exposure routes include lead-acid batteries, paint chips, fertilizers, utilized ammunition, pesticides, and other industrial byproducts. The means of conveying lead from key emission sources is mainly through the air. Concerning the sources of lead in drinking water, normally lead reaches into the residents’ water after it is channeled from their water treatment plant or the wells. To be more precise, the source of lead in people’s water supply largely emanates from their households’ pipes or lead solder from plumbing. The most typical cause of the lead formation is from the corrosion reaction by the lead pipes or solders and the water. The acidity as a result of the low pH, dissolved oxygen, and little mineral contents in the water are main reasons of the corrosion. The lead amounts in the water become high if the water spends a long duration of time stagnated inside the old pipes.

(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).

Lead was discovered in 3000 BC, making it one of the earlier metals discovered. Lead became popular due to how easy it is to

Lead poisoning has been a concern for many years. In fact, because of the affects of lead poisoning, there has been an extensive decline in its use. "Many people believe lead poisoning is no longer a threat, yet millions of homes contain lead based paint" (Heck, J., 2005, para. 1). Exposure to lead at any level is unhealthy, especially in infants, children, and pregnant women and continues to be an ongoing dilemma in this country. I read two articles concerning lead poisoning; the first article is from FineTuning, a popular press and the second article is from Pediatrics, a peer-review journal. In this paper, I will clearly summarize each article by comparing the content of both articles. In addition, I will summarize the attention to

Potential lead contamination from drinking water presents a significant health risk. Recent examples of this lead contamination include Flint, Michigan, a city that experienced a large increase in the number of people, especially children, who exhibited symptoms of lead poisoning. A March 9, 2016 article in the Washington Post reported data from the Environmental Protection Agency that indicated approximately 350 schools and day-care centers across the US failed lead tests approximately 470 times between 2012 and 2015. Seven years ago, according to the Post, a study concluded that hundreds of young children in Washington, DC, had potentially damaging amounts of lead in their blood due to contamination in the city’s tap water. The toxin can cause permanent developmental and behavioral issues.

Unfortunately, it has proven to be deadly for humans, especially for children. Lead production shifted into high gear in the 1920’s. Chemists figured out lead could be marketed in gasoline which is called tetraethyl-lead (TEL). The creation of this product led to the birth of the Ethyl Lead Corporation (ELC). ELC formed in 1923 by General Motors and Standard Oil Company of New Jersey. It was purchased by Albermarle Paper Manufacturing Company in Richmond, Virginia in 1962. General Motors sold the company due to the growing concerns of the product. Researchers discovered that TEL contributed to the soil, air, and water lead pollution and toxic to humans. Lead made the gasoline more efficient, however; its lead pollution levels increased over 625 times over the previous levels. The Lead levels were a huge concern for General Motors. They did not want to be liable for anything. During the 70's and 80's, car manufacturers moved towards unleaded gasoline, but the damage was

The major sources of lead here were gasoline, paint chips and water from old plumbing. After lead was removed from gasoline and paint, blood lead levels (BLL) in children decreased on average from 16 mcg/dL to less than 3 mcg/dL. Residual lead persists in the environment, however. A toxic level is currently defined as 5 mcg/dL. In U.S. children age 1-5, the prevalence of BLLs >10 mcg/dL decreased from 88% to 4.4% between 1976 and 1994 and further dropped to 0.8% by 2010. Yet there are still almost half a million children in the U.S. with levels >5

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.

Kevin Drum’s article on lead, in short, is an argument for the removal of lead from the environment while mainly focusing on the link between crime and the use of tetraethyl lead in gasoline. Drum believes that cleaning up the lead from the environment in the US would improve crime rates, increase the cognitive performance of the general population, and generate hundreds of billions a year. These are fairly outlandish claims until he further examines what lead does to the early development of children.

There are multiple reasons to expect that a person's lead exposure as a child could affect

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

The improved screening and treatment of lead poisoning decreased the severity of symptoms usually seen. However, the level of lead in the blood does not establish what symptoms are seen, since lead in blood only establishes current exposure. Recently, studies have shown that a long exposure to low amounts of lead may have severe neurobehavioral effects that are not diagnosed until the child enters school (Singhal et. al., 1980).

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)

* Lead. Lead is hazardous to health as it accumulates in the body and affects the central nervous system. Children and pregnant women are most at risk.

To please the public the industry also said they would conduct research about the effects of lead, but the research was funded by the lead industry so they skewed the presentation of the results to the public. Soon there were also cases reported of lead poisoning in children from their habit of biting lead-painted toys. This time the lead industry tried to distract the public by increasing their advertisements highlighting the benefits of lead using the mascot of the Dutch Boy Painter and slogans, such as “ethyl is to gasoline what vitamins are to food.” However, by the 1970’s with the introduction of safer elements and the decrease in public support, the lead industry lost its importance in the world.
