Lead poisoning

As the health and safety manager, I’ve identified that workers were exposed to cadmium and lead. Cadmium is a soft malleable transition metal. It is silvery bluish-white in color. Although toxic by nature, this chemical element is commonly used to create dry cell batteries. Like mercury, cadmium has the lowest melting point of groups three through eleven transition metals. Lead is a malleable soft heavy metal that is denser than most common materials. It bluish-white in color when freshly cut,…

4. Metal poisoning came to the foreground of the American consciousness when a spotlight was shown on the high lead levels in Flint’s water system in Michigan. Although many steps have been performed to reduce lead poisoning, namely in children, such as removing lead paint from homes in 1978, removing lead from gasoline, and proposing stricter laws on imported toys containing lead, heavy metal poisoning still exists. Chelation therapy is still the preferred medical treatment for such heavy metal…

Common Loons to lead poisoning. Knowing the deaths would be detrimental to a severely threatened population, an investigation of dead loons, collected from 1989 to 2010, was carried out by the Loon Preservation Committee, Dr. Mark Pokras of Tufts University, and Tiffany Grade, a graduate student from the University of Wisconsin-Madison. Necropsies and tissue samples showed lead poisoning was responsible for nearly half of all the dead birds examined. Despite legislation in place to ban lead…

Advancement in Radiation Protection: Non-Lead Apron People are exposed to radiation every day just by being alive on this earth. One receives approximately 3,000 µSv of ubiquitous background radiation a year, which means approximately 8.2 µSv per day (Howerton, Iannucci, 2012). This is known as background radiation and is caused by terrestrial, cosmic, and naturally occurring radon. On the other hand, during radiographic examination some degree of biological damage does occur during exposure,…

FOR more than two decades Wittenoom in WA’s Pilbara region was a mining stronghold. The small country town which lies around 1400kms northeast of Perth was also, at one stage, the only place in Australia that produced blue asbestos. But when demand for the deadly mineral began to wane and fears of serious health concerns began to emerge, the operation was shut down in 1966. However it was another decade before authorities realised the blue dust that swept throughout the town was extremely…

Introduction Lead (Pb) contamination is a pervasive issue in many low-income neighborhoods throughout the United States. The toxicity of lead poses significant risks to human health, and proves to be especially harmful for children in terms of cognitive and physical development. Lead in the environment is primarily related to a legacy of anthropogenic sources including leaded gasoline, leaded paint, and various industrial applications. Although the presence of heavy metals is ubiquitous in the…

Which 1980s New Romantic pop group released a song entitled, "Fade to Grey"? Having started out hosting club nights at Billy's nightclub in Soho, founding members Steve Strange and Rusty Egan wanted to tap into the growing New Wave culture of syntho-pop, forming Visage in the late 1970s. Recruiting amongst others, Midge Ure and Billy Curry - whom also performed with Ultravox - the band's first single was a cover of Zager and Evans "In the Year 2525". This record though proved to be a…

Lead (Pb) is one of an important contaminant surrounding our environment. Lead occur naturally in all soil and water (1), or can be found deep within the ground located in ore (2). Although lead can be found in small quantities, there is a great quantity of lead flow in the environment that is detrimental to human beings and plants. However, despite lead is a toxic metal, there are still lots of households products contains lead; burning of paper products, discarded rubber, battery casings, and…

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…

should have an eye catching, but refined title to avoid pandemonium; it must also contain pertinent information about the health hazard of mercury deposits in various fish and how to avoid excessive consumption of fish which could potentially lead to mercury poisoning. Furthermore, schools can be influential in bringing awareness to the issue of mercury in fish that we consume. This can be achieved by incorporating information about heavy metals in our ecosystem and their hazards to humans…
