Abstract
This paper looks at whether or not mercury poisoning causes malformations in young children. There is some evidence for brain damage in fetuses from mercury which crosses the placenta and the blood-brain barrier, but there is no conclusive evidence on malformations caused by mercury poisoning. Mercury is a neurotoxin, so most of its affects are within the nervous system.

Abstract
This paper discusses the chemical properties and uses of mercury. It particularly discusses the medical uses of mercury and then goes on to describe the concerns of using mercury for medicinal purposes. The paper discusses the fact that government regulatory agencies are being pressured into loosening mercury pollution controls, despite the fact that history and science have shown the risks of mercury poisoning. The paper concludes by discussing the possible link between mercury in childhood vaccinations and the development of autism.
From the Paper
"Thimerosal, or thiomersal, is an organic compound containing mercury, that is used as an antiseptic and antifungal treatment Originally trademarked under the name Merthiolate in 1929, it has been "used as a preservative in vaccines, immune globulin preparations, skin test antigens, antivenoms, ophthalmic and nasal products, and tattoo inks." (Wikipedia 2006c) Most childhood vaccinations not longer contain thimerosal, and are instead stored in single-dose vials that do not need the same preservatives added. It was first used as a bactericide in vaccines in the early 1930s, and by the mid 1980s it was used in the vast majority of vaccines. In 1999, the American Academy of Pediatrics requested the removal of thimerosal from all pediatric vaccines. Today, thimerosal is still used in a few United States vaccinations, and "The World Health Organization, with US funding, is providing thimerosal-containing vaccines (TCVs) for children in developing countries with the same amounts of thimerosal, as were given American children at their peak exposure levels." (Wikipedia 2006c)"

History of Lead Poisoning
Incidence of the Problem
Epidemiology of Lead Poisoning
Pathophysiological and Biochemical Basis of Lead Poisoning in Children and Adults
Recommendations to Eliminate Lead Poisoning as a Public Health Hazard
Summary and Conclusions
From the Paper
"Lead has been used by mankind for centuries, but the dangers associated with its use have only been identified fairly recently. The research showed that in spite of some progress in recent years, lead poisoning represents one of the leading preventable public health threats for young people in the United States and abroad today. The research showed that there are no safe levels of lead exposure for children, and lead levels as low as 10 [micro]g/dL have been shown to affect child development. A host of other health issues are implicated in lead poisoning as well, but most people tend to recover completely if appropriate treatments are provided in a timely manner. Finally, the research was consistent in emphasizing the inherent problems in addressing the problem of lead poisoning among low-income families where the exigencies of daily life preclude concern over this potential threat. Clearly, lead poisoning represents a challenging and ongoing threat to the nation's welfare, and public health officials continue to pursue increasingly aggressive campaigns to address the issue, but the studies to date suggest that these initiatives will remain ineffective unless and until the economic disparities that exist between the world's affluent and poor are addressed first."

Abstract
This paper explains that mercury preparations and compounds are a vitally important component of U.S. production in a wide range of industries, but its use carries with it some known health and environmental risks. The author points out that the coal, agricultural and healthcare industries, which use mercury compounds, are most likely in favor of the legislation because of a lack of a suitable alternative. The paper recommends that the U.S. Senate support the proposed legislation because it represents a viable approach to moderating the impact of mercury emissions across the board, provides those industries that are not currently able to achieve EPA standards with the opportunity to improve and is cost advantageous.

"How is this proposal likely to play out in the press? Clearly, this is an emotionally charged issue that is fraught with opportunities for misunderstanding among the public, and these misperceptions about the safety record and importance of mercury in many industrial applications may be overlooked. There is, in fact, valid reason for concern. According to Stadler and Murray, during a 12-month period beginning in 2000, several major developments in mercury-related industries emphasized the need for oversight in order to eliminate mercury pollution and exposure in the United States."

Click here to show/hide summary
Abstract
The United States Department of Health and Human Services (1991) reports that childhood lead poisoning is one of the most common pediatric problems in the United States. The result of industrialization, the report notes that lead is ubiquitous in the American human environment and children are particularly susceptible to its effects. This paper proposes a research study to examine parental knowledge of childhood lead poisoning as well as related knowledge and perceptions in a sample of Michigan parents living in a large urban area of the state. The paper begins by presenting a review of the pertinent literature. It continues with a brief description of the problem of childhood lead poisoning, including its sources and common treatment options. This is followed by a review of the few studies that have been conducted to explore for parental knowledge of the condition. The paper then explains the research design for the proposed study, including methodology, instrumentation and statistical analysis plan.
From the Paper
"Interested in recommendations for screening for lead poisoning, Goldman et al. (1998) attempted to determine the screening practices of a state-wide, representative sample of New Jersey physicians (N = 333) to examine whether practices were consistent with key CDC recommendations. Approximately 60 percent of the sample engaged in practices that were not in accord with CDC recommendations. Only 42 percent of the interviewed pediatricians and 24 percent of family practitioners said they screened the majority of the children in their practice by age 2 years. About 60 percent of all respondents reported not providing lead exposure education to half their patients."

Abstract
Discusses the serious problem of mercury pollution. Dangers to children and the developing fetus. Industrial air pollution as the major source of mercury pollution. Power plants and automobiles as other sources. Growing problem of mercury polluted waters on fish and humans who eat fish. Lack of effective treatment. Control measures.
From the Paper
"Summary
Mercury toxicity is a serious problem since mercury does not degrade in the environment and so once it is there as a contaminant, it is difficult to remove. It is highly toxic, particularly to children and the developing fetus, where it interferes with development, particularly the maturation process of the brain. Whatever form mercury is in - elemental, inorganic, or organic - it is toxic, and there is no truly effective treatment once it gets into the human body. Chelation therapy may help, but there are doubts as to its effectiveness or its ability to reduce the toxic effects which may have already occurred.
Most mercury pollution comes from industrial air pollution, although more and more water is becoming polluted from industrial ..."

Abstract
This paper explains that the symptoms of campylobacter food poisoning usually present within 2-5 days after the consumption of the organism and include diarrhea, which may have blood or white blood cells in it, fever, abdominal pain, nausea, headache and muscle pain. The author points out that campylobacter is commonly found in raw chicken, raw milk and non-chlorinated water; the bacteria can be destroyed, thus preventing food poisoning, by cooking chicken, pasteurizing milk, and chlorinating drinking water. The paper relates that, although they are rare, there are a number of complications associated with the disease: Reactive arthritis, hemolytic uremic syndrome, septicemia and infections of organs, meningitis, recurrent colitis, acute cholecystitis and Guillain-Barre syndrome; the estimated case/fatality ratio for all C. jejuni infections is 0.1, meaning one death per 1,000 cases.

From the Paper
"While there is usually only a small population of people affected at a time, generally fewer than 50, Bennington, VT experienced a "large outbreak involving about 2,000 people while the town was temporarily using a non-chlorinated water source as a water." Dairies can be responsible for outbreaks when children become infected during field trips, or if they do not properly pasteurize the milk according to industry standards, such as the case in 1986 when 32 students of an elementary school became infected."

From the Paper
"Cadmium poisoning was chosen as a topic because it is a threat that can be avoided and because it is not a well-known source of poisoning. Better knowledge of the issue would help reduce incidence. Cadmium, the name for which was derived from the Greek kadmeia, is a zinc ore that resembles tin. It is a metallic blueish white element with the atomic number 48 and the atomic weight of 112.40. Cadmium has many uses in industry. At one time, Cadmium was included in medications, but these have since been replaced by less toxic drugs. A recurrent problem is cadmium poisoning, brought about through the inhalation of cadmium in fumes created by welding, smelting, or other industrial processes involving solder. Cadmium bromide is used in engraving, lithography, and photography and can cause severe gastrointestinal symptoms if swallowed. Cadmium poisoning may also be caused by the ingestion of acidic foods prepared and stored in cadmium-lined containers, such as lemonade in certain metal cans."

The Biochemistry of Lead Poisoning, 2003.
A look at the chemical mechanisms and biological effects of lead poisoning.
1,395 words (approx. 5.6 pages), 9 sources, MLA, $ 46.95
»

Abstract
This paper describes lead poisoning, focusing on the chemical processes that take place as lead (II) displaces zinc (II) from ALAD and inhibits hemoglobin synthesis. The technical details of the inorganic and biochemical processes at play are explored and discussed, as well as the mechanisms of various lead poisoning therapeutic strategies. This paper also contains several referenced illustrations and figures.
From the Paper
"The protein ALAD, also know as porphobilinogen, is crucial in heme biosynthesis (2). ALAD, a ZnII metalloenzyme, consists of A and B subunits each of which contain a zinc atom when functional. The functionality of the A and B sites has been determined experimentally by displacement of zinc. When magnesium displaces zinc at the A site ALAD is marginally active. Furthermore, when magnesium replaces the zinc in the B site no change in the activity of the enzyme is observed (3). Thus the A site is key to the activity of the enzyme. However, when PbII displaces the active ZnII ion present in the A- site, the enzyme is rendered useless."

From the Paper
"Chairman and President of the National Center on Addiction and Substance Abuse at the Columbia University Joseph A. Califano, Jr. called for a down-the-line and complete change not only in attitudes towards substance abuse and addition (Manchikanti 2007). He also called for a radical change in the nation's systems in healthcare, criminal justice, social service and education in addressing the drug abuse issue. He backed his position up with the statistical revelation on the stealthily rising incidence in prescription drug abuse. This, he said, was the hidden reality to the publicized success in the control of alcohol and illicit drug use and the decrease in the incidence in teen smoking, the abuse and addiction to controlled prescriptions and stimulants. He stressed that prescription drug abuse had accounted for increasing emergency hospital visits and unintentional deaths (Manchikanti)."

Abstract
The paper discusses current government advisories that suggest limiting the consumption of certain fish because of high levels of mercury. The paper also discusses, however, how shellfish and seafood are an important part of a healthy diet. The paper addresses the risks that shellfish and seafood pose to the average US citizen and reveals that there is conflicting and biased evidence as to the actual risk involved. The paper concludes, therefore, that fears over fish consumption are exaggerated, but one should still follow government advisories regarding fish consumption.

From the Paper
"Since the 1800s people have been aware that fish contain high levels of mercury (Ferguson, 2005). The harmful effects of high levels of mercury in the human body have been known for many years as well. Recently, there has been a rash of media hype about the dangers of mercury to the developing fetus and to small children. This has led to suggestions that the public avoid consumption of certain shellfish and seafood above certain levels. However, this denies the known health benefits of fish, including the important Omega-3 fatty acids and their heart protective properties."

" The Removal of Mercury and Mercurial Compounds From Wastewater
Over the past several decades, increasing attention has focused on wastewater reclamation. Legislative measures aimed at protecting the environment currently regulate wastewater composition. In addition, with greater demand for fixed natural water supplies, wastewater renovation has become more important. Potential reuses may include agricultural and industrial processes; wastewater may even find its way into potable supplies. The processes involved in wastewater reclamation are complex. A multitude of pollutants may be present in any given effluent. One contaminant which has long been recognized as a potential threat to human health is the metal, mercury. Within the environment, mercury may take a variety of forms. Perhaps the most toxic of these are the methylated mercurial compounds."
