Once used for varying applications, lead is now known for its toxicity in the human body. Dr. Gary Goldstein, the chief executive of Kennedy Krieger Institute wrote, “Exposure to excessive amounts of inorganic lead during toddler years may produce lasting adverse effects upon brain function (Goldstein 1990).” Lead poisoning awareness has become increasingly prevalent in the American government, with lead poisoning testing recommended as early as nine to twelve months of age (Health and Human Services 2011). This paper will explain briefly lead’s history and industrial uses, as well as give an in-depth analysis on lead’s exposure to children and how it affects their developing brains.
Lead, simply put, is an element found in the earth’s crust. It is slightly soluble in water and is transported mainly through the atmosphere (Harte et al. 1991). The human usage of lead dates back to five- thousand years ago when it was discovered that small quantities of silver could be extracted from lead ore (Harte et al. 1991). The ancient civilizations of Phoenicia, Egypt, Greece, India, and China used lead for vessels, roofs, water ducts, utensils, ornaments, and weights (Harte et al. 1991). Romans used lead acetate as an artificial sweetener in their drinks. Lead acetate, known as sugar of lead, would sweeten a vintage without causing further fermentation, which would have occurred with the addition of sweeteners like honey (Le Courteur and Burreson 2003). The Romans also used lead pipes for plumbing their homes with water. The Latin name for lead is Plumbum (like the word plumbing) hence the symbol Pb on the periodic table (August 1998). Only the rich Romans had access to water in their homes through lead pipes. Lead poisoning from th...

In conclusion, lead is a very widespread poison that has been intertwined throughout the history of mankind. To prevent poisoning from this toxic substance, foods should be washed prior to cooking of eating. Hands, particularly those of young children, should be washed before meals (Harte et al. 1991). Flaking lead-based paint needs to be removed by a professional; intact lead paint on buildings should be maintained occasionally by painting over using lead-free coatings. Joggers and cyclists should exercise away from traffic and avoid peak driving hours (Harte et al. 1991). As a nation, strides are being made to lower contact with lead on day to day bases. On the other hand, countries around the world need to learn from history’s mistakes on lead usage; otherwise, they are just going to repeat the past.

... water crisis will have a long term affect on those who are consuming this water on a daily basis. Lead attack the brain and can cause coma and possibly death. Children who survive lead poisoning are left with serious health issues such as metal defects and leave a child mentally unstable. Even at lower levels of exposure symptoms such as behavioural changes such as reduced attention span, reduced intelligence quotient (IQ). Children with smaller amount of lead exposure also showed increased anti social behaviour, it also reduces educational attainment. These side effect of high lead exposure can leave children scarred for life. The water crisis in Flint Michigan car scar children for life. This could all be resolved if they could come to an agreement and replace the water pipes, allowing for cleaner and healthier water to be accessible to citizens in Flint Michigan.
Paul Thompson in the article “Startling Finds on Teenage Brains” claims that a teenager is not an adult and should not be treated as one. Thompson supports his claim by first explaining about the research his group has done. He then describes the results of the research by stating, “But what really caught our eye was a massive loss of brain tissue that occurs in the teenage years… are only being lost in the areas controlling impulses, risk-taking and self-control”(Paragraph 7). This means that during the teenage years, those part of the brain are vastly immature. Lastly, the author explains that during this reshaping of the brain, it does not remove their accountability. He also states, “While research on brain-tissue loss can help understand
In the article Industrial Urban Agriculture: The Potential and Challenges of Producing Food in Cities, Caroline Schneider talks about the challenges of growing local sustainable food. In the article she says, “Several contaminants can be found in urban soils, and lead is the most prevalent. (Schneider). ” This quote argues that although no chemicals are used, there is still potential danger in eating the food. But later she also says that you can fix that problem by simply cleaning the food. In the article it says, “Practices such as washing food well before eating and covering soils with mulch can help decrease these risks. (Schneider). ” This quote proves that as long as you take the proper steps to clean your food and help your soil, your food will be safe. Local Sustainable is safe and healthy for
This is why the Flint water crisis is so critical today. Because young children are being exposed to lead and they should actually be screened from the lead. The pipelines with lead in the water system and the whole community of Flint, not being able to drink water out of the facet as well as not being able to
Lead is a metal found virtually everywhere even today. Sources of lead include auto body shops, electric storage batteries, glazes for china dishes, crockery, insecticides, electric cable insulation, hose, pipe, sheet and floor coverings. Lead is associated with stain glass work, jewelry making and antique ceramic doll painting. Although lead in paint was outlawed, there are still many homes that have lead paint (White et al, 1990). Lead found in gasoline was found in one study to account for 23--27% of the lead blood levels in the people tested (Wagner, 1991). This exposure to lead sources is more of a concern for children due to the characteristic habit of children to taste everything they touch; this characteristic is known as pica. Children are also in closer contact with their lead polluted environment during play. They are more active and exposed to outdoor contaminates and they inhale dust and dirt that are lead contaminated. Furthermore, the adsorption rate of lead in the digestive tract is up to 10 times greater in chil...
Reports on the neurotoxic properties of Aluminum (Al++), as well as those of many other heavy metals, date as far back as the end of the nineteenth century. In 1965, Al was found to induce the formation of neurofibrillary tangles (NFT) in animal brains. These NFT’s were similar to those found in brains of patients suffering from Alzheimer’s Disease (AD). Vast research thus, was targeted at defining the possible etiologic role of Al in AD. However, several findings, among them the fact that Al++ induced NFT’s are structurally different than those found in AD, have contributed to reducing the importance placed on Al++ as an etiologic factor of AD. The Al++ theory, however, still remains a theory, and further research needs to be done before it can be disproved.
When lead enters the environment, it starts to become a problem. After a period of about ten days, depending on the weather, it falls to the surface. Here lead builds up in the soil particles. Where it may make its way into underground water or drinking water due to the fact the grounds acidic or if it's soft enough. Either way it stays a long time on the soil or in water. Months or years down the road after the lead has built up it starts to become a problem for children that play outside of their homes . This lead containing soil particles get on the child's hands or clothing and end up in the child's mouth. After the build up of so much lead it leads to lead poison. Lead poisoning has been an issue since the early 1900s, when the use of lead started being banned from the manufacturing of paint in foreign countries such as Australia. Unfortunately, the United States did not start banning it until 1978, when it finally became illegal in our nation. Today 90% of the lead in the atmosphere comes from the burning of gasoline. This problem has been a large issue since the 1920s, when the Environmental Protection Agency started making laws on the amount of lead allowed in gasoline.

As children begin to develop and grows, they all are curiosity and learning about the world around them that need to develop their thinking and learning more that included toys. Toys helps children to used their imagines and learning skills to play and imagines as heroes from the stories and children television show which Jean Piaget believe that toys can help and enhance the children’s cognitive development that is defined as the construction of thought processes, including remembering, problem solving, and decision-making, from childhood through adolescence to adulthood. Piaget also stated that there are four stages in his cognitive development theory which are the Sensorimotor Stage-Birth through about 2 years where children will learn about

Paul Thompson in the article, “Startling Finds on Teenage Brains”, claims that the youth thinks differently, especially when it comes to them facing criminal charges. Thompson supports his claims by first citing an example of a real case involving a minor. He then cites research from reliable sources as evidence to back up his claim. Lastly, the author investigates the law system’s way of handling the case mentioned previously in the article as a way to leave options open for the viewer. Thompson’s purpose is to convince the audience that though the research given shows that youth suffer brain tissue loss in their teen years, it gives them no excuse for violent behavior so that he can possibly give a well informed side of the argument.

Due to an above average level of poverty, many homes in New Orleans had very high levels of lead and arsenic in them. (Pastor) This combined with eighty percent of the city being flooded, released significant amounts of lead and arsenic into the environment which still exist today. Soil samples taken before and after Katrina showed elevated levels of lead, iron and arsenic. (Reible)A new study on one-hundred and nine households found that sixty-one percent had lead measurements above federal standards with twenty-seven percent greater than one-thousand two hundred ppm which was significantly higher than the five-hundred and sixty ppm collected before Hurricane Katrina. (Rabito) These inorganic compounds are related to cancer risks of which New Orleans already has a significant problem with. This complicates the decision on when and where to conduct environmental clean-ups in New Orleans to remove the lead, iron and arsenic.
Symptoms of lead poisoning include loss of appetite, weakness, anemia, vomiting, and convulsions, sometimes leading to permanent brain damage or death. Children who ingest chips of old, lead-containing paint or are exposed to dust from the deterioration of such paint may exhibit symptoms. Levels of environmental lead considered nontoxic may also be involved in increased hypertension in a significant number of persons, according to studies released in the mid-1980s. As a result, the U.S. Centers for Disease Control in recent years have been revising downward the levels of environmental lead that it would consider safe.
Addressing the issue of regulating mining waste disposal is imperative due to the potential damage mining waste can cause to the environment. Mining waste are composed of undesirable heavy metals as well as solvents and compounds used to extract ores chemically. These chemicals are often not natural to the environment and can cause significant damage to various parts of the body. For example, the metals present in mining waste, such as arsenic, manganese, lead, and cadmium, have been shown to alter dopamine release in rats. The study, published in 1998, demonstrated that “rats exposed to mining waste released more dopamine, less DOPAC, and less HVA by about 15, 50, and 55 pentagram per microliter, respectively, compared to rats not exposed to mining waste when release [of dopamine] is stimulated” (Rodriguez, et.al 489). It is important to notice that these metals only compose a fraction of mining wastes, and that mining industries produce more waste than what is exposed to the ...
