Lead Exposure Essay

The Agency for Toxic Substances and Disease Registry says that lead exposure in children may cause comas, seizures, and death. Because a child’s brain is still developing, the damage of lead exposure is more severe. Not only does lead affect the way the brain physically develops, but lasting neurological and behavioral damage includes lower IQ scores, higher risk of attention deficit disorders and hearing impairments, decreases in impulse control, and potentially violent behavior. Mona Hanna-Attisha, a pediatrician who runs the pediatric medical residency program at Flint’s Hurley Medical Center, studied blood lead level tests and found that the percentage of children with elevated blood lead levels had gone from 2.4 percent to 4.9 percent citywide (Barry-Jester). Hanna-Attisha’s findings showed a rise to sixteen percent in neighborhoods where lead levels were known to be elevated in the water. She points out, "Lead only last in body a short time … and when you screen them, it's no longer elevated. So we've missed children's peak lead levels and that's why everyone says it

(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).

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,

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!

At the age of just a year old, Reginald Cureton, a Detroit middle schooler, was just a year old, a blood test proved he had four times the level of lead in his blood that was concluded as lead poisoning. His parents were baffled and doctors said it would alter his brain development and hinder his skills as a child. Reginald's elementary school suggested numerous times that he repeat the third grade. This lead his parents to do test him for any mental stagnancies and he was diagnosed with ADHD. Now in middle school, Reginald and his family's fight against lead- exposure is continued and as strong as ever as they are taking extra precautions to reduce his lead exposure in any way possible (Lead-Exposure Problems Spotlighted in Detroit) . Unfortunately

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.

Cadmium is dangerous because it can cause kidney failure. It travels in the blood toward the liver where it shares bonds with proteins. It then travels to the kidneys where it can gather.

Children under six years old are very easily affected to the effects of lead. Even low levels of lead in the blood of children can result in: behavior and learning problems, lower IQ and hyperactivity, slowed growth, hearing Problems and anemia; lead can accumulate in our bodies over time, where it is stored in bones along with calcium. For pregnant women, during pregnancy, lead is released from bones as maternal calcium and is used to help form the bones of the fetus. This is particularly true if a woman does not have enough dietary calcium. Lead can also cross the placental barrier exposing the fetus the lead. So lead can cause serious effects to the mother and her developing fetus, including: reduced growth of the fetus and premature birth. And for other adults, lead can also be harmful, it can cause cardiovascular effects, increased blood pressure and incidence of hypertension, decreased kidney function, and reproductive problems in both men and

Lead is poisonous because once it enters your body it can form into other atoms like zinc and iron fooling the body into thinking they are there and not carrying out the vital functions they need. Lead atoms can also block neurotransmitters. In the 1920s there was essentially a lead "boom" and marketers began putting lead in everything including shoes, lightbulbs, and leaded gasoline, advertising that it was safe and even kid friendly (in some items) when it wasn't. The lead levels in the factories became so bad that the workers were becoming sick, hallucinating, going mad, and dying from being poisoned by lead. Scientist Robert Kehoe was hired by GM to "cover up" the lead threats saying the amount of lead was a naturally occurring. No one cared about the use of leaded gasoline and other leaded materials until Clair Patterson began to dig deeper into the research of lead in the

The improved screening and treatment of lead poisoning decreased the severity of symptoms usually seen. However, the level of lead in the blood does not establish what symptoms are seen, since lead in blood only establishes current exposure. Recently, studies have shown that a long exposure to low amounts of lead may have severe neurobehavioral effects that are not diagnosed until the child enters school (Singhal et. al., 1980).

When lead enters the human body, it is distributed to the brain, liver, kidney and bones. It is deposited in the teeth and bones where it accumulates over time. Exposure to high levels of lead may cause anemia, kidney and brain damage. Lead exposure can also cause miscarriage and infertility. The effects are even more severe in children. Lead can affect children’s brain development resulting in decreased intelligence quotient (IQ), shortened attention span and increased antisocial behaviour. At high levels of exposure, lead may attack the brain and central nervous system, causing coma. Children who survive severe lead poisoning may continue to suffer mental retardation and behavioural disorders. Furthermore, pregnant woman exposed to lead can

Health officials agree that no amount of exposure to lead is safe, be it from water, the air, old paint, or dirt. Even the smallest of amounts can lead to irreversible cognitive and developmental damage, especially in younger children.

Lead is extremely dangerous to young children. If a child drinks water with lead in it, they run the risk of experiencing delays in mental and physical development. Drinking this toxic water can also lead to attention and learning disabilities.

Lead, a naturally occurring metal and can be used in almost everything. It can cause serious health issues if it is exposed for a long time, particularly in children as they are more susceptible to absorbing and retaining lead in their bodies. Each year, in the United States 310,000 of 1- to 5-year age group are found to have unsafe levels of lead in their blood, which can cause a wide range of symptoms. (1)

Cadmium is a naturally occurring element that occurs in the earth’s crust and water and is released into the atmosphere through fossil fuel combustion, waste incineration and metal production. It is commonly found as a mineral combined with various elements such as chlorine, sulfur, and oxygen. Most rocks, soil, mineral and coal fertilizers contain cadmium. The element enters the environment through the action of rain and wind and mining operation. Volcanoes and forest fires release cadmium into the air. When humans consume cadmium, it can cause severe stomach irritation and be the cause of diarrhea and vomiting. Inhaling high levels of cadmium damages lungs and causes death, and is a cancer-causing agent. Humans are exposed to this element
