Lead Poisoning: Why Do Fireflies Blow In The Dark?

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.

Most people do not see color as simply the way something looks, however. They tend to associate certain colors with specific feelings, emotions and memories. (Dmitrieva) For instance, blue is most commonly associated with “feeling blue” meaning one feels upset or depressed, however, blue is

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.

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

Many service lines leading into homes are leaching lead into the water. This problem happened because the city of Flint decided to not treat the water properly with corrosion control (Ganrin, 2016). This proves that officials did not care about those living in Flint. They chose to save money but instead they destroyed many lives. So this proves that our government is not there to help the people out, but instead to cut money wherever they feel necessary to not have to take it from other places. Lead poisoning can affect IQ and behavior. This can cause some people to become score low on standardized test and to become violent and to sometimes harm others. No level of lead is ever safe in any person or animal (Ganrin, 2016). The water source in Flint is currently undrinkable and very unsafe and will continue to be for months ahead ("Researcher: Flint water 'like Russian roulette'," 2016). Flint water is not a safe water source and has not been for many months. According to federal regulations Flint's water supply still does not meet standards. Since August 2015 the water supply has improved, but it still is not safe ("Researcher: Flint water 'like Russian roulette'," 2016). The people of Flint have been poisoned under their noses without even knowing it, secretly being sickened by their own government. Flint’s water is not safe it's an unreliable water

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.

In April of 2014 Flint, Michigan started to get their water from the Flint River rather than the Detroit river that was formerly used as the main water source in hopes of saving money. The water being provided has been classified by Flint residents as smelly and murky and is avoided at all costs. It has also been discovered to cause damage to the lead pipes that transported it throughout the city. Children have been found to have high levels of lead in their blood and this may be the cause of an outbreak of Legionnaire’s disease which has killed 10 people in the Flint area. People have also reported rashes from the dirty water. Video news interviews show residents holding water that is

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 article “How Tap Water Became Toxic in Flint, Michigan” By Sara Ganim and Linh Tran talks about the toxicity in the tap water from Flint, Michigan. In the article it is described that the levels of led in Flint's’ water system was because there was a corrosive agent in the water that was taking led off the pipes and putting it into the drinking water. The start of everything happened when Flint stopped paying Detroit for water and switched to a temporary source until they could build their own pipe to lake Huron. The temporary water source that they switched to was the Flint river. The water in the Flint river is 19 times more corrosive than the water from the lake Huron. Pipes that carried the water were not used to the level of corrosion

Chemistry is a branch of science that deals various compositions of matter which involves investigating properties that affect us directly, including our environment and our way of life. One of such issues is the public water contamination of Flint, Michigan. The state experienced a water crisis for almost two years continuously, which highly devastated the town since its main water source had been contaminated. There were increasing levels of lead in the city’s drinking water (Broadsidedpress.org). The issue started in 2014 when the city of Flint changed its source of water from their original source, Detroit Water and Sewerage Department, where they received treated water, to the Flint River. Drinking water from Flint River had a series of problems, including lead and bacterial contamination, which led to serious health issues (Dixon). Flint River water was corrosive thus it caused lead from old pipes leach into the water supply and this caused very high levels of metal neurotoxins in the water. So many children have been exposed to the contaminated water leading to a series of health issues. The children have elevated blood-lead levels and the number increased drastically from 2014 to 2015 (Dixon). The change in the water source also led to Legionnaire’s disease breakdown that killed more than ten people while affecting another 77 in 2015. Due to this issue, many people and organizations stepped in to aid the city of Flint by providing them with bottled

The poor water that is flowing into the homes and business in Flint, Michigan has struck headlines for the past couple of months. The water has been reported tot contain extremely high levels of lead. These high levels of lead are extremely unhealthy and are harmful not only to those that are currently coming across. This water but also for their future generations. Although turning to the Flint river in theory will save the city money, the idea has taken a turn and the city is forced to suffer.

Strictly speaking, blue is nothing but light that is reflected off the surface of an object and into receivers. These receivers then send electrical impulses to the brain that then interprets the impulses as blue. In that case, what more is color other than the interpretation of electrical signals? Without the stimuli and the receiver, there would be no color. In that case, color is only defined by the measurement of something else. A scientific approach to seeing color reveals a puzzling explanation.
