explanatory Essay
723 words
Lead Many elements, like lead, are very important to the structure and formation of many of the products we use. Throughout history, lead has been developed, mined, extracted, and used. Lead, since its finding thousands of years ago, has proven to be a tricky element with many diverse health effects. Scientists have developed products, and processes that still continue to used lead. Lead is an extremely important and influential element in our daily lives. Lead has many different physical and chemical properties. Being a solid at room temperature, lead is the heaviest member of the carbon family (1). Lead can by physically described as a soft metallic gray color, and tends to be formed naturally with jagged edges. It is also a very ductile and malleable element. When exposed, rust tends to form on the surfaces of lead. Being a softer element, Lead can be easily bended, cut, pulled and changed (2). Compared to other elements, when used to conduct electricity lead does very poorly. Lead also has many Chemical properties. Lead has very few chemical properties. Lead does not burn, dissolves very slowly in cold water/ cold acid, and slightly faster in warm acid (1). …show more content…

- Explains that lead is important to the structure and formation of many of the products we use. it has been developed, mined, extracted, and used.
- Explains that lead has many physical and chemical properties, including a soft metallic gray color, ductile and malleable element, and is toxic to both people and animals.
- Explains that the periodic table is a prime way to learn about the basics of lead.
- Explains that lead began to be extracted nearly 8,000 years ago, and still maintains a use in the modern society.
- Explains that lead can be extracted from more than 60 different minerals, including galena, cerussite, and anglesite. there are 8 steps required in extracting lead from its ore.
Lead is commonly referred to as Pb due to its chemical symbol on the periodic table (7). The Element as has an atomic number of 82 (7). From its atomic number, scientists can conclude that a natural element of lead contains a total of 82 protons, and 82 electrons (8). Lead also has an atomic mass of 207.2 (7). Being that the atomic mass is the number of protons plus the number of neutrons, scientists concludes that an atom of lead contains 125 neutrons along with the 82 protons (8). Lead is considered a poor metal on the periodic table. Lead is also in the p block of elements which means that its valence electrons will be in a p shell (8). Overall, the periodic table is a prime way to learn about the basics of

- Lead Poisoning Essayexplanatory essayLead is considered to be a toxic heavy metal. It occurs naturally in the Earth’s crust. However, it tends to combine with other elements to form lead compounds. (Registry, 2011). Moreover, it has no known function in the body and with excess accumulation, either acute or chronic, will cause a wide array of metabolic dysfunctions by interfering with normal metabolic functions (Analytical Research Laboratories, 2012). From a historical standpoint, most human beings if not all have accumulated some lead in their bodies over the course of their daily lives. In extreme cases, that is, when there is too much lead in the body it is known to cause lead poisoning. In order to fully understand this phenomenon, one must first acknowledge; how lead enters the body, how it is distributed, and how and if it is eliminated.

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...

What are the options and barriers to moving it forward?General Effects of Childhood Lead Poisoning When lead in inhaled it, the lead could be deposited in the bones where some essential body function occurs e.g. blood formations, calcium absorption. Lead is also transported in blood stream and deposited in muscle and nerves and blood vessels. The deposition of lead in these organs systems eventually results in the malfunctioning of these organs. These malfunctions could include decrease in bone and muscle growth/co-ordination, damage to the nervous system and other organs of the body. (KidsHealth, 1995-2010) The above mentioned effects could also impair breakdown and use of nutrients by the body, decreased hearing ability. In addition, it affects child growth, in the sense that it has been shown that children with higher blood lead levels may on average be shorter than their genetic potential by 1cm.Effect of Lead on cognition and Behavior of Children: Lead poisoning have been identified as one of the factors responsible for cognitive deficits and mental illness among children.

1704 wordsRead More - Lead Poisoning: A Pediatrician Must be Informedexplanatory essayOne of the things that a pediatrician should be focused on after reading an article about toxic toys should be the science and research that has been done on this topic. Until recently, clinicians thought that a child either had lead poising or they did not, and there was no in between. At this time, the elevated pediatric lead level was said to be a concentration in whole blood of over 60 micrograms per deciliter (Landrigan, 2000). However, pediatricians should be aware of Herbert Needleman’s research that showed that lead could alter children’s behavior and reduce their intelligence at blood lead levels lower than 60 micrograms per deciliters. Most recently, the blood lead level has been reduced to 10 micrograms per deciliters in 1991, and pediatricians should be fully aware of this (Landrigan, 2000). This decrease in blood lead level is due to the widespread removal of lead in things such as gasoline and paint (Falk, 2003). Pediatricians should know this so that they may be able to offer a small piece of comfort to the parents of their patients, because they will know that lead poising is preventable,...
