Lead levels are a huge affective issue in America, mainly schools. Public schools in New York are reporting that there are lead levels in their water fountains. Later did researchers realize that the amount of children with above average lead levels in their blood had doubled. This water crisis has been affecting the blood of young school children. Lead levels are the amount of lead building up in somebody’s blood.
This water crisis effects are unhealthy water sources. Also, there are lead-filled water fountains that can build up in your blood. This water crisis is directly affecting school attending students. The lead that builds up in students blood causes abdominal pain, abdominal cramps, aggressive behavior, constipation, sleep problems,
Humans need water. In a world that is overpopulated, we use a lot of water and other natural resources. Currently, in our world, clean water is getting scarce. Recently, for example, Flint, Michigan, had a water crisis. In early 2016, the water was discovered to be tainted with lead and other toxins. Long before that, the Michigan Department of Health and Human Services, and Governor Rick Snyder along with his council, knew about the lead, but to save money for the city of Flint in early 2014 Snyder had changed the city’s water source to the Flint River which had corroded pipes, causing people of all ages to be sick from the high amounts of lead
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...
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.
lead are more prone to developing ADHD. Some scientists in Brittan have linked a higher
Huddie William Ledbetter also known as "Leadbelly" was an American folk singer and blues musical, most famous for his strong prominent vocals and his ability to play thetwelve-string guitar. Leadbellys astounding ability to play the guitar combined with his personal life experiences provided the foundation for his musical career. He also wrote about mainstream culture and black culture in general to express feelings of anger, sadness, and expose the wrongdoings of American society against blacks.
... 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.
... environmental quality leading health indicators are air quality index exceeding 100 and children of ages 3 to 11 exposed to secondhand smoke. Poor water quality can lead to gastrointestinal illness, neurological problems and cancer. Poor air quality can cause cardiovascular disease, cancers, and asthma. Certain chemicals found in homes and workplaces can contribute to severe poisonings and other toxic serious effects.
Investigatiing Whether the Thickness of Lead Inside a Pencil Affects the Resistance Aim The aim of this investigation is to find out whether the thickness of a lead inside a pencil affects the level of resistance when connected to and electrical circuit. Prediction I think that lower resistance will be shown in the results from pencils with thinner lead because the current will ba able to pass through the lead easier. Preliminary Test Our preliminary test was for the purpose of finding out whether doing the investigation in different ways would affect the results. We started with putting a high current through a pencil first, taking our results, and then lowering the voltage. Then we did the opposite, starting with a low voltage, taking our results, and re-testing with a higher voltage.
Lead and lead compounds can be highly toxic when eaten or inhaled. Although lead is absorbed very slowly into the body, its rate of excretion is even slower. Thus, with constant exposure, lead accumulates gradually in the body. It is absorbed by the red blood cells and circulated through the body where it becomes concentrated in the soft tissues, especially the liver and kidneys. Lead can cause damage in the central nervous system and apparently can damage the cells making up the blood-brain barrier that protects the brain from many harmful chemicals.
...anganese levels include hypertension, psychiatric illnesses, mental confusion, impaired memory, loss of appetite and neurological problems. Well water containing a high manganese content can lead to excessive manganese intake and increased bacterial growth (Blaurock-Busch, 2002). Except for one isolated incident, which still remains unclear, manganese intoxication due to drinking water has not been recorded. In 1941 in Japan, the cause of a disease similar to encephalitis was attributed to well water with a high manganese concentration of 14 mg/L. However, other metals like zinc were also present in excessive concentrations and it was never confirmed whether the high level of manganese was, on its own, responsible for causing the disease. Regarding the acceptable daily intake, no adverse health effects were noted in humans with the following daily manganese intakes:
Recently, the environment impacts on our health have become a large concern of our societies worldwide. Lead is a pervasive and persistent environmental pollutant and recognized to be a major public health problem; therefore it has been paid attention by researchers in probing further into its toxicity. Lead poisoning is an insidious disease which is often detected late after being confused with other disorders such as digestive, hepatic, hematologic and behavioural disorders where it decreases the activity of certain enzymes by binding their sulfhydryl groups, or even to replace other metal ions
Thousands of people are affected by the lack of school safety in schools across the nation. Students everywhere are attending schools that are more dangerous than expected. This is a growing concern everywhere, and schools need to improve, or else they are prone to being unsafe. Whether it is building, drill, concussion, social, or technology safety, schools need to improve to lower the risk of an incident.
The water in your home is probably safe to drink, but places like Flint, Michigan have polluted water or no water at all. Two articles “For the World’s Poor, Drinking water can kill” and “After Pollution in Flint, Some Find Tap Water’s Benefits Hard to Swallow” detail events of polluted water or people refusing to drink water because they heard about the problem in Flint. However, there are many similarities and differences between these articles.
These days, school safety is one of the most important parts of running a good school. So how can we make our school, safer and a better school overall?
