...LEAD POISONING IN CHILDREN Introduction: Lead poisoning results from the accumulation of lead in the blood and body tissues of those individuals that are frequently exposed to lead. Lead is a heavy metal which is naturally occurring in the soil. It is recognized on the periodic table by its chemical symbol [82Pb]. Lead poisoning is most common in children between the ages of 1 -2 years. Its adverse effects are also most devastating among this age group. Lead is mined and extracted for many industrial and domestic uses. Hence the ease of indoor and outdoor exposure. Chronic exposure to Lead could result in severe morbidity and mortality in affected individuals. Adverse effects of Lead poisoning range from seizures to mental retardation and even death in children. Childhood lead poisoning remains a major environmental health problem in the United States. A more disturbing fact is that even children who appear healthy can sometimes have dangerous levels of lead in their bodies. [8] Short History of lead poisoning: Lead was first mined in Asia Minor (today Turkey) about 6500 BC. A 6000- to 8000-year-old lead necklace was found in the ancient city site of Anatolia. Lead's easy workability, low melting point and corrosion resistance were among its attractions. Lead toxicity was first recognized as early as 2000 BC. Nicander of Colophon wrote of lead-induced anemia and colic in 250 BC. Gout, prevalent in affluent Rome, is thought to be the result of lead, or leaded eating...

...Lead poisoning can have serious effects on development in children. Because lead is present everywhere in our environment, parents need to be especially diligent to supervise their children when around known lead sources (Graziano 2002). Lead is not only dangerous to youth after birth, but also while still in utero, as it is a teratogen. One case example of this is a pregnant woman who had been shot 15 years prior to pregnancy. A bullet had been lodged in her spine and remained there. The lead from the bullet caused lead poisoning in her and her child (https://www.poison.org/articles/2011-dec/unusual-sources-of-lead-poisoning). Symptoms of lead poisoning can be misleading and only with a blood test can it be determined. However, common symptoms and long-term effects are abdominal pain, sleep problems, headaches, high blood pressure, anemia, and kidney dysfunction. Prolonged exposure can lead to low IQ, problems with hearing, and growth delays. Further, very high toxic doses of lead poisoning could even produce “emergency” symptoms like muscle weakness, seizures, and coma (https://www.healthline.com/health/lead-poisoning#symptoms)....

...Pica Disorder: “Eating disorders are a serious mental illness, not a lifestyle choice.” Millions of people have to deal with inner demons on a daily basis, some more serious than others but one that is severe, is Pica disorder. Pica disorder is an eating disorder where people have an appetite for non-nutritive, inedible materials and become addicted to eating items such as clay, nail polish, drywall, light bulbs and much more. This disorder causes victims to eat unimaginable things and causes many medical problems in the process. Some doctors believe that this disorder is just complication of the mental psyche, but there is more underlying issues that cause this disorder. Thus, Pica disorder is caused by a combination of biochemical, environmental and psychological factors. Biochemical factors are located in the brain and are chemical or mineral that control our brians health. A patient can have an abundance or a shortage of certain chemical or mineral, which can cause serious problems within the brains processes. Many victims that have pica disorder, have severe iron and zinc deficiency. Therefore patients begin to crave certain item that one would not normally desire such as magnets, light bulbs, nail polish, and much more that contain high amounts of iron and zinc in there make up. They tend to eat an abundance of materials that satisfy what there body is craving. At some point the victims tend to believe that what they are ingesting is helping them so they continue...

...produces many different chemical compounds and solutions, including the ever controversial lead additive used in gasoline in some developing nations. The company, which was originally founded as an oil company, eventually acquired several other corporations and extended their oil business into one that handles chemicals such as bromine and eventually took over the company Octel which produced a lead additive. While the use of leaded gasoline became illegal in the US and all developed countries, it was still in heavy use in developing countries. These countries had yet converted to non-lead use, impart by the total control of these businesses by the government who cared solely on their profits. By a technological standpoint, Great Lakes uses minimal technological advances in its production of the lead additive, along with their other chemicals. With the advancement and use of non-leaded gasoline, all other chemical companies stopped producing the lead additive, mostly to comply with new regulations enforced against the environmentally unsafe additive. The company has been faced with dramatic push backs from environmentalists who urge the company to stop the production of this. The main issue with following through with this is that their economic situation has been extremely successful. The company itself is a billion dollar company, with well over half of their profit being from the lead additive itself (Octel). Although the company was beginning to see small declines in...

Mitchell Western Governors University Table of Contents Situation Synopsys 3 Possible Alternatives 3 Recommended Course of Action 4 Future Actions 5 References 6 Whistle Evaluation Situation Synopsys Toy Company had developed and sold a child’s toy set containing a whistle. These sets are set to be sent to the South American market, primarily elementary schools, for order fulfillment. The toy has been found to contain levels of lead that exceed what is considered safe in the U.S. marketplace. Possible Alternatives In order to evaluate each of the following possible alternatives Toy Company needs to establish some level of a decision making matrix. For example each alternative needs to be evaluated on three core questions. What is the cost, in dollars, of this alternative? What is the potential for harm to the consumer by using an alternative? What is the long term impact to Toy Company by moving forward with this alternative? In the process of asking and answering all of the questions a more plausible outcome evaluation will develop. In the evaluation and decision making process the long term impacts need to also be considered, some of the choices may potentially strengthen the relationship with the consumer. All of the considerations need to always be tested with the question “Is this the right thing to do?”. Each...

...Eating habits have been changing rapidly in modern India. While traditionally, Indian families used to cook food at home with healthy ingredients and knew what went into the meal, in modern times, with rising incomes and affluence, more and more people are moving away to readymade fast foods and eating regularly at restaurants. The food in many of these outlets is cooked with poor quality ingredients to attract and satisfy the palate rather than provide a wholesome nutritional meal. We now have a lot more varieties and the choices are many. Though, some of us may not be aware of the fact that the food we consume may be adulterated, 25 to 30 per cent of the food items in India are intentionally adulterated. Impure, unsafe Food adulteration is the addition or removal of any substances to or from food, so that the natural composition and quality is affected. Adulterated food is impure, unsafe and not wholesome. Food can be adulterated intentionally and accidentally. Unintentional adulteration is a result of ignorance or the lack of facilities to maintain food quality. This may be caused by spill over effect from pesticides and fertilisers. Inappropriate food handling and packaging methods can also result in adulteration. Intentional food adulteration is usually done for financial gain. The most common form of intentional adulteration is colour adulteration. Some examples of intentional adulteration are addition of water to liquid milk, extraneous matter to ground spices...

...Lead (Pb) is a malleable, ductile, heavy metal that is resistant to corrosion and is bluish-white in color but turns gray and tarnishes when exposed to air. It is a moderately active metal, dissolves slowly in water, and does not burn. It is naturally occurring in the Earth’s crust. Its abundance is estimated to be between 13 and 20 parts per million. It rarely occurs as a pure element and its most commonly found in the form of lead sulfide (PbS). Children are the most vulnerable population susceptible to the health hazards of lead exposure. They are more sensitive to elevated blood led levels, are more likely to ingest toxins due to frequent hand-to-mouth activity, and are more likely to breathe lead-contaminated dust and soil as well as fumes close to the ground. Increased lead levels in pregnant women may pose risk to the developing fetus. Low lead levels that may harm the fetus and cause neurological problems in newborns may not present risk to the mother. Women may also store lead in their bones from prior lead exposure that can be released during times of calcium stress such as pregnancy and lactation. Elevated lead levels in pregnant women pose an increased risk of preterm labor, miscarriage, spontaneous abortion or still birth, and low birth weight. Other major at risk populations include adults whos occupations are in lead-related industries including lead smelting, refining, and manufacturing industries. People who participate in activities...

...Memorandum To: Mr. Jones, CEO CC: Executive Leadership Team From: Shannon Peaden, Elementary Division Manager Date: [ 10/13/2013 ] Re: South American toy collection shipment Confidential A. South American toy collection alternative decision actions 1. Since the lead limit in South America apparently regulated as tightly as it is here in the U.S. the company should proceed with the shipment as scheduled. This decision alternative came to me when I realized that I couldn’t locate a lead level for South America. After a few unsuccessful Google searches for South American lead level regulations, the automatic thought is that this is not a heavily monitored in that country. This Advantages of this alternative * The obvious cost savings achieved by not having to repackage the collection = positive financial move for the company. * Avoidance of the receiving company finding out about the production error, and on time shipping proceeding as scheduled = this is dishonest and unethical. The difference between right and wrong is obvious to me, personally. * Avoiding bad publicity Disadvantages * Potential to harm a child with increased lead levels * If the client were to find out about this incident after the fact, your company could lose a business deal. Word of mouth also travels fast regarding negative client experiences. This decision is ethically unsound. If one of the children were to get sick after playing with one of the whistles...

...Lakes. Describe how Great Lakes will be affected by each of these external factors. Social/Demographic Segment-Ellie Shannon, the Division Manager for Great Lakes Chemical Corporation had a concern for what option was to offer regarding the continued use of lead based additives in developing countries. Even though it was not illegal to do so, Ms. Shannon considered the potential effects this decision would have on Great Lakes to compete in global markets and if it would impact the company positively or negatively as a corporate citizen. Technological Segment-Great Lakes was a company that always sought to keep up with technology and ways to make its product better. During the 1950s they focused on petroleum production and from there moved into the bromine and chemical business. Great Lakes developed chemical products for applications such as water treatments, specialty household cleaners, flame retardants, polymer stabilizers, fire suppressants, and performance chemicals. Great Lakes took on the production of lead additives and that is where they made the majority of their wealth. Economic Segment-Great Lakes made very wise decisions as far as investing in companies such as Octel Associates, a tetraethyl lead (TEL) producer, which accounted for over most of the company’s total operating profit per year. Even when the company was down they were still up because business was just that good because they made a great investment. When Ms. Shannon was trying to decide whether...

...SUMMARY: During routine product testing, item 32167 was found to contain levels of lead that exceed U.S. allowable limits. This finding may impact a recent order scheduled to be shipped to Department of Elementary Education in South America. The client is expecting delivery next week. Remedies to the situation must be weighed carefully. Financial impact, changes to the company’s reputation, potential liabilities, as well as, social and ethical responsibility should be thoughtfully considered prior to moving forward. The company will incur a cost associated with these findings; the decision that must be made is how we pay the price; with dollars or with our reputation. Considering the above, there are three options, outlined below, that may mitigate the situation. OPTION 1: Ship the items as scheduled. RATIONALE: This option is the simplest. It requires nothing more on our part than to fulfill the existing contract. ADVANTAGES: No further cost incurred. We fulfill the contract with on-time delivery. By delivering the product as requested and on time, the client will be happy and contract with us in the future. The children will be happy with their new toys. DISADVANTAGES: Children could be harmed. South American equivalent of Consumer Product Safety Commission could test the items and determine the lead content and insist on replacement or refund. Our reputation as a company could be damaged internationally, as well as domestically. ETHICAL CONSIDERATIONS:...

...named Elmer Galbraith who has mysteriously contracted lead poisoning and is frantically searching for the cause to his illness. Throughout the story Carey uses suspense and dialogue to grab the attention of the everyday reader. The most obvious way that Carey builds interest is by creating suspense. He begins the story by describing the symptoms that Elmer has, continuing to do so for the first five paragraphs. As the story progresses, the interest towards Elmer’s illness grows. Once Carey has the reader hooked, he reveals that Elmer is actually suffering from lead poisoning. After Elmer’s illness is revealed, the reader stars to wonder what is actually causing the lead poisoning, which creates even more suspense. Using suspense keeps the reader interested and alert throughout the story. If Carey simply stated at the beginning that Elmer suffered from lead poisoning obtained by chewing plastic wire coating, then the reader would not read the rest of the story to learn about the symptoms and complications of lead poisoning. By creating suspense, Carey ensures readers actively read and understand the story. Another way that Benedict Carey is able to grab the interest of the reader is through dialogue. Reading words that were actually spoken by the characters is an excellent way to draw the audience into the story. For instance, the conversation between Galbraith and Kelley about the possible causes of the lead poisoning successfully accomplishes this goal. The reader gets a...
