Lead Exposure Research Paper

Lead concentrations can be measured in various body tissues or by measuring the biomarkers of the toxic effects of lead. The concentration of lead in the body has been measured in blood, bone, nails, hair, teeth, urine, faces and saliva for screening and diagnostic purposes. In all samples, specimen collection, storage and processing must be meticulously performed to avoid contamination of the samples with lead in the surrounding environment. Teeth, nail and bone reflect long term exposure to lead. The loss of lead from teeth is much slower than the loss from bone and this might make teeth a better indicator of lifetime lead exposure (Schütz et al., 1996; Barbosa et al., 2005).

Lead can be measured in whole blood and plasma to indicate current

    In “Lead Contamination in Flint - An Abject Failure to Protect Public Health” David Bellinger examines the impact Flint’s contaminated water has and will continue to have on its population, primarily the children. In 2014, executives from the Flint Water Treatment Plant decided to use the Flint River as the main source of water instead of Lake Huron as a “cost saving measure.” The river is polluted with lead from older, now defunct industrial factories which specialized in products that contain harmful byproducts. One of the water-purifying agents used in the Flint River is ferric chloride which has an effect on naturally occurring bio-matter in water, increased corrosiveness.…

    One of today's silent villains is lead poisoning. It is one of the most prevalent sources of childhood health problems. Each year, several hundred children in Yount County are treated for serious cases of lead poisoning. There are countless others who are suffering silently because their symptoms are either too minor or they go unnoticed by parents, teachers and other authorities. for example, consider the case of Janice Brown in northwestern Yount County.…

    Acid, below-normal pH, causes many problems in our world today—from drinks to teeth, from pollution of industry to natural disasters. Acid is a chemical substance that can subdue alkalis, can dissolve specific metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in English:"). Alkalis is any kind of substance that can produce OH ions, hydroxide ions, in water, which can also be known as 'basic', or 'basicity' ("GCSE CHEMISTRY - What is an Alkali? - What is a Base? - GCSE SCIENCE."). Litmus is a weakly acidic, organic…

    The article Fetal Death and Reduced Birth Rates Associated with Exposure to Lead-Contaminated Drinking Water by Marc Edwards discusses some incidents regarding lead exposure, along with the correlation between this complication and fetal death, as well as miscarriages. At first glance the observation and claims being shown seem constructed with specific diction concerning a science, more precisely, ecological science. Throughout Edwards’s article, the claims presented are accompanied with the use of charts and notation. When viewing this notion of lexicon, it is suggested that the intended audience should possess knowledge and be familiar with certain vocabulary, as stated in the first sentence, “in children at thresholds >5 μg/dL and also >10 μg/dL” (739). We assume this as Edwards does not further elaborate on his charts and notations, leaving a portion of audience unsure of the truth and meaning behind these claims.…

    Lead poisoning occurs when there is an immense build-up of lead in a person’s body. This can happen over the course of a couple of months, to years. It is extremely serious and can sometimes turn into a fatal condition. Lead is usually found in certain paints, art supplies, or contaminated dust. It can enter the human body through inhalation or consumption.…

    To start we will be looking at blood’s role in distribution of lead. Blood plays a major role in the distribution of lead even though it has a tendency to carry a small fraction of the total amount of lead present in a body. This is due to the fact that blood is constantly circulating and coming into contact every single part of the human body. Lead found within the blood system on average has a half life nearing only 1 month. Next is distribution and storage through the accumulation of many soft tissues.…

    Situations are not always as they appear. While a situation, prima facie, may seem ethical, taking a deeper look, one may uncover nuances that lead to seeing the situation as unethical. In this essay, I analyze the Lead-Based Paint Abatement Repair and Maintenance Study (1992) conducted by the Kennedy Krieger Institute, in order to provide an ethical analysis of the study. In doing so, I argue that the ethics of the study shifts depending upon which set of non-moral facts an individual chooses to focus on. My stance, however, is that the study was unethical.…

    Introduction In the wake of the recent lead poisoning incident in Flint Michigan, I chose to evaluate the case-controlled study, “Lead Levels Among Children Who Live in Public Housing”. According this study, lead exposure typically occurs in public housing or housing built before 1950. The Centers for Disease Control and Prevention (CDC) estimated that millions of children, per year, are exposed to lead. Side effects of the exposure include, but are not limited to: speech and hearing problems, slowed growth, behavioral problems and a host of other long term (poor) health conditions.…

    One study published by The Journal of International Medical Research explored the effects of a thiamine and zinc combination supplementation treatment on lead poisoning (Flora, Singh, & Tandon, 1989). The hypothesis was that a mixture of the two would treat lead poisoning better than just thiamine or zinc alone. Measuring the lead concentration of rats who were exposed to just lead, thiamine and lead, zinc and lead, or all three and analyzing and comparing the results was the objective of this experiment. It was anticipated that the combination of thiamine and iron would work better than individually and could be potentially used for treatment of lead poisoning in the future. This would be much safer than normal treatment.…
