Lead Poisoning Research Paper

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.

In this day and age consumers always want more and they want it at the lowest price possible, but are they willing to risk the danger that could derive from it? Hundreds of thousands of toys are imported daily from overseas countries, such as China, into the United States, some toys are inspected for irregularities, but most are not. This may not seem like such a problem but the truth of the matter is that it is one of the larger problems in the nation right now. Children’s toys imported from China are found to be contaminated with high levels of lead and infecting American children with lead poisoning. Some people may say that this is an unnecessary argument, that China isn’t doing anything harmful, maybe it was just a few faulty toys,

The lead effects in the drinking water have caused a massive public health crisis (“Scientific Opinion on the risks”, 2015). The whole crisis was as a result of poor management practices employed in the Flint water plant. The city decided to switch the

Similarly, in the article, The Need for Vigilance: the Persistence of Lead Poisoning in Children published in Pediatrics, a peer-review journal, the authors write the article with the intent of reiterating the need for medical professionals to remain vigilant with the accurate treatment of lead poisoning. The article in Pediatrics is written by doctors for clinical professionals and is based upon a report of "a case of lead poisoning associated with ingestion of a toy necklace in a 4-year-old child" (Florin, T., Brent, R., &

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.

Imagine you're drinking a cup of water and every single drop is poison. This could be happening to you. 50% of the United States have lead in their drinking water. This is because of lead based pipes. Lead based pipes have been leaching lead into water which connects to drinking water. It can also be because of the state's water utilities that might have lead in their water. ( EPA's safe drinking water information system database reports, three, 2016 by Isabella DC, USA Today) says Lead can cause brain damage, cancer, seizures, hearing loss, learning disabilities, and more!

In the article “It’s All Just Poison Now”, Oliver Laughland and Ryan Felton discuss how the lives of the residents of Flint, Michigan have been negatively affected by the city’s tainted water supply. Flint’s aging lead pipes, coupled with its corrosive water sources, have cause a number of contaminants to seep into the water supply. On top of this, the city’s water supply is inadequately purified, which caused many residents to be exposed to these toxins. The main concern to residents is the presence of poisonous lead in the water, which can be deadly even in low amounts. The community of Flint has been unknowingly drinking and bathing in these chemicals, despite being told by city officials that the water was safe. As a result, many residents

The rules for lead and copper have changed over the years, so let’s start at the beginning. Lead was originally regulated under the Public Health Service Act of 1962, which established a guideline of 0.050 mg/L (ppm) for lead in drinking water. This was carried over into the Safe Drinking Water Act of 1974. It wasn’t until 1991 that regulation changed significantly under the Lead and Copper Rule. This rule regulates how public water supplies must deal with the potential of lead and copper in the drinking water. Additionally, there is also the Reduction of Lead in Drinking Water Act, which regulates the amount of lead that can be in products that could come into contact with drinking water, like pipes, plumbing fitting, fixtures, solder and flux.

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

When the contamination in Flint’s water system was noticed, it was because of the “smell, taste, and color.” (The Humanist 23) The water pipes were deteriorating because of the polluted water, which was causing lead to flow into the water. People immediately started complaining to their city’s mayor about the changes in the water. Soon after that, scientists from Virginia Tech discovered it was severe lead in the water. Lead poison is known to destroy or affect almost every organ or system in someone’s body. (The Humanist 23)

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.

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.

Lead poisoning in children was first discovered in 1890 in Queensland, Australia. The lead source was not identified until 1904, when a researcher traced it to the paint used on railings and verandahs. The first discovery of lead poisoning in the United States (with a traceable source) was in 1914; the child had chewed the paint off of his crib. At this time they linked lead poisoning as a cause of convulsions in children. As research progressed and more children were found with high lead levels, symptoms caused by lead were expanded to include lead meningitis, acute encephalopathy, intellectual dullness, reduced consciousness, seizures, comas, and death (Chisholm, 1982).

Lead poisoning is one of the global burden and need to be focused a lot on preventive strategies.

Moreover, exposure to lead and taking a lot of medication without consulting a doctor may lead to
