Lead Poisoning In Prenatal Development

(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 current water crisis in Flint, Michigan stems from government officials changing water sources. The government of Flint switched from using the water of Lake Huron, which they had used for over 50 years, to using the water of the Flint River, which had a high level of chloride. The high chloride level eventually led to the corrosion of water pipes allowing unhealthy levels of chlorine and lead contamination. Additionally, irresponsible and unreliable water treatment allowed even more contaminates to enter the city’s water source. All this pollution ultimately ended up in the homes of thousands of people, poisoning families throughout the city. Lead poisoning can have disastrous effects on the human body, with some symptoms including “memory loss, anemia (lack of healthy red blood cells), kidney dysfunction, and in severe

All the inhabitants of Flint communities regardless of their location had irreversible, permanent brain damage due to lead-contaminated water. It started when traces of E. coli and total coliform were found in the Flint River. The city addressed this problem by increasing chlorine levels in the water, causing the pipes to corrode, releasing lead into the waters. Total trihalomethanes (TTHM) were also formed in the water (they are carcinogenic to humans).TTHM is a disinfection byproduct that occur when chlorine interacts with organic matter in the water. At this stage, The lead levels in the water was 13,200 ppb. Water is considered hazardous waste at 5,000ppb (NPR 2016). This tragedy goes to show that this toxic runoff, or even the miss-handling of the water resources in a watershed can affect everyone as the downstream water was piped up into the upstream communities.

“…It drops your IQ, it affects your behavior, it's been linked to criminality, it has multigenerational impacts. There is no safe level of lead in a child." Dr. Mora said when she was talking about what lead poisoning does, and it is devastating, knowing that generations of kids are affected by this event and so will the next generation after them. This also could have been prevented if the state added anti- corrosive agents that would have cost about $100 a day, and experts say 90% of the problems with Flint's water would have been avoided. If officials would have done this then thousands of people would have been saved from

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

An essential necessity for life is slowly killing residents in Michigan. The town of Flint, Michigan is slowly being poisoned by their water supply. Flint is 70 miles north of Detroit with a population of 98,310. According to the U.S. Census Bureau a little under half of residents live below the poverty line. More than fifty-five percent of the city’s population is African-American (CNN Library). The dangerous lead levels in the water went unnoticed for years, despite the residents’ complaints of discolored and foul-smelling water. The question at hand is how could this happen?

The article, “Lead Levels Remain High in Flint’s Water” by Matt Davenport explores the increased lead contamination in the Flint, Michigan water source. In April of 2014, high levels of bacteria, and fecal matter were detected in the water of Flint, Michigan. While the levels of bacteria decreased, the city’s water still breaks the federal rule for lead levels. A series of tests conducted by Marc A. Edwards was able to show that the city’s contaminated water was corroding pipes, which leached lead into the water. Because Edwards was able to inform the public about the contaminated water source, Michigan officials have taken steps to improve Flint’s water quality. For example, the water-pipes were re-routed to carry water from Detroit instead

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

“In September, Virginia Tech researchers released a report saying Flint's water was creating a health threat in old homes that have lead pipes or pipes fused with lead solder. And doctors last week reported high levels of lead in local children's blood samples, also blaming water pipes” (CBSNEWS). Lead is a serious problem as it may cause a serious damage in different organs of the body especially the brain and it is the most known neurotoxin. However, knowing that lead is the source of the problem is an important piece of information which can facilitate reaching the source of lead leaching. In fact, many cities have lead pipes, not only Flint city, and when water sits in those pipes, the lead can leech into the water. So cities usually add corrosion-control chemicals, such as phosphates (PO4), to keep the lead out of the water. However, Flint did not take into account these precautions, and this was a major contributor to the high lead levels and, consequently, health problems, “the public health protection was gone,” Edwards says. (ALANA SEMUELS, 29 Jul. 2015). If we talked about the reason why the water in Flint’s River is difficult to treat, it turns out that it contains high levels of coliform and fecal coliform bacteria. But what makes it more difficult than Lake Huron water is that the Flint River is subject to temperature changes, rain events and high carbon content. An additional indication, is the increased level of trihalomethanes (TTHM), a byproduct of the large amount of chlorine needed to kill bacteria in the river water. For the most part, specific amounts of chlorine are used to treat river water, but the problem is that low levels of chlorine can produce coliform bacteria and, on the other hand, high levels of chlorine may result in Disinfectant Byproducts (DBP), which, in turn, may lead to elevated levels of

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

All the controversy about the lead problems in Flint, Michigan has stirred up questions across the country. Every day there are several news stories about cities across the country discussing the lead issue and how they meet the requirements of the Safe Drinking Water Act. While the average person may feel comforted by these news stories, it doesn’t mean that every home served by the water supply has lead below the EPA’s recommended action level. It’s the job of water treatment professionals to educate those served by municipal water about the regulations surrounding lead and copper and what those consumers can do to protect themselves further.

Imagine being informed that the water with which you bathe, brush your teeth, and cook is the root of many serious and sometimes fatal health problems. Sadly, this is the case for a majority of the citizens in Flint, Michigan. According to an online article titled “This is how toxic Flint’s water really is,” by reporter Christopher Ingraham, the culprit is high concentrations of lead that have leached into tap water from lead-containing pipe systems and fixtures as they slowly corrode. The article also informs that although nearly all citizens were exposed to the hazardous water, some exposures were found to be worse than others (Ingraham). Additionally Ingraham states “A group of Virginia Tech researchers who sampled the water in 271 Flint homes last summer found some contained lead levels high enough to meet the EPA 's definition of ‘toxic waste." With lead being the culprit, and nearly all citizens being exposed to the contaminated water, Flint has found itself in a near epidemic.

The more polluted a water source is, the more processing required to make the water safe to drink. Most of the contaminants now in Flint’s drinking water were introduced during or after processing. For all drinking water, the first concern is bacteria, which can cause diseases like hepatitis, Legionnaire’s disease, and other illnesses. Because Flint’s river water had high levels of bacteria, it was treated with additional chlorine. Chlorine reacts with organic material in the water to produce carcinogenic byproducts such as trihalomethanes; it also makes water more acidic, which corrodes pipes. Federal law mandates adding anti-corrosive agents to drinking water in large cities; this standard water treatment practice was not followed (Carmody, 2016). The water created issues with lead due to its high acidity. Water service connections have been made for years using lead piping primarily in the 1920s and 1930s. The acidic water corroded the old lead pipes and lead seeped into the water. Lead poisoning is the most widespread and serious health problem associated with Flint’s drinking water; children with prolonged exposure to lead experience a range of developmental problems that are incurable. Flint’s water-treatment staff were not able to successfully make Flint River water safe to drink. Whether this is because they were undertrained, understaffed, or simply made a decision not to invest scarce

In the 1950’s and 1960’s, lead poisoning was found to be prevalent in the slums of the inner cities. These areas were referred to as the "lead belt" because these run down houses were havens for lead exposure. The flaking paint on walls, the chipping plaster ceilings, and the old furniture exposed these children to a real hazard. Pica was an important contributing factor and children, ages 1 to 3 were at the greatest risk. Siblings in these situations were often affected and recurrence was common because the lead paint was not removed. The prognosis for these children became worse with each recurrence (Chisholm, 1982).

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