Lead

The element I got was Lead, Lead is a chemical element that is assigned the symbol Pb it is from the Latin plumbum and it is a bluish-white element, Lead is not really rare but since it is fairly widespread and easy to extract it typically occurs in very small amounts in ores and is found in the ores galena, anglesite, cerussite and minim also the earth’s crust contains approximately 0.0013 percent lead. Lead can be toxic to humans and animal but is found mostly in combination and used a lot in cable

was lead. Lead was used many years before and it is still used a lot today. Lead is still very useful and is found in many things that were used a long time ago and things we still use today. Lead is a very poisonous element that can really harm your skin and your body. Since lead is very toxic, it’s not recommended for children. Lead is also the heaviest of the carbon family. Lead was used by the Romans for water pipes, aqueducts, tank linings, and cooking pots. In the 21st century, lead remains

Lead is toxic if inhaled or ingested. It gets into the blood stream, travels to other parts of your body and stores itself in your bones. It interferes with the production of red blood cells (leading to anemia) and absorbs calcium. The Center for Disease Control and Prevention (CDC) stated that nearly one million children in the United States has levels of high lead that causes irreversible damage to their health. The CDC’s current “level of concern” regarding blood level testing is set at ten

possibly believe that the correlation between the percentage of lead exposure in a person correlates with the amount of crime in the United States? The lead-crime hypothesis is a hypothesis proposed by the economist, Steven D. Levit that claims that increase blood lead levels in children had an affect on the amount of crime happening in the United States. As know by much of society and almost all scientist increase blood-lead levels can lead to multiple disabilities in children which includes but is not

Lead is a chemical element that is in the carbon group. The symbol is Pb and has an atomic number of 82. Lead can be used for weapons and cosmetics. However, there are advantages and disadvantages of using this element. A disadvantage is that if you are repeatedly exposed to this toxic element, it can cause anemia, brain damage and high blood pressure. An advantage is that lead has a low melting point, so it is easy to shape and mold the bullet. Bullets were originally either made out of stone

Importance of Lead Poisoning * It can cause serious harmful problems effects on the body including: hearing, anemia, peripheral neuropathies, wrist/foot drop, encephalopathy, seizures, coma, and even death. It can also cause children to have lower IQ scores and behavioral issues. * Lead stays within the body for decades, stored within the bones of the human body. * In pregnant women, lead can cross the placental barrier and cause harm to the fetus such as reduced growth and prematurity

contaminated with lead has heightened public alarm. It has been further stoked by news of more results of tests on residents that reveal lead levels in blood in excess of World Health Organisation guidelines, with a medical expert warning of possible exposure to potential health risks, including harm to an unborn baby and to the developing brain and nervous system in children. Until now confidence in the safety and security of the city's water supply has long been a given. The lead contamination is

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

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,

general population’s exposure to lead , research continues to demonstrate significant increases in risk of adverse outcomes in both children {Wigle, 2005 #96;Lanphear, 2005 #18} and adults {Guallar, 2006 #32;Lustberg, 2002 #59;Navas-Acien, 2004 #60} at low blood lead levels. In addition, millions of people carry elevated body burdens of lead, from past exposures, that may induce present and future health effects {Nash, 2003 #99;Nash, 2004 #100}. Given continued uses of lead by human societies (primarily
