Week 5 – Final Lab Report Paper

SCI207 Dependence of Man on the Environment, Marc Hnytka

Week 5 Final Paper

Abstract My report was based on the how ground water may be affected by myriad containments present in our experiment and in our everyday . Surprisingly when vinegar was filtered through dirt it came out fairly clean. This surprised me because I would never believed that vinegar had such a profound effect on water considering its oily nature. I was convinced that vinegar more than the other contaminates would have produced a wider, more polluted field. I believed that all the water would have been contaminated with the dirt had been mixed in. This exercise may demonstrate the need to discover better more efficient ways to filter and purify water in the future.

Introduction This Lab we explored how contaminants affect the water supply. Contaminants can be commonly found in household products from dishwashing soap to paint, to oil and more. There are more robust versions like pesticides and petroleum products within the farm system. We will explore why and how this affects the water table and what type of effects, if any we will witness drinking water from the tap. Working in the environmental field one contaminant I come across frequently is Lead. It is found frequently in older homes. It has been found in paint, canned goods and in our water supply. Research has shown that lead poisoning can lead into developmental issues, negatively harm the reproduction system and can ultimately lead cancer. Lead from environmental pollution is not carcinogenic, but even low dose lead exposure has been shown to have detrimental and long-lasting effects on the renal, hemopoietic and nervous system (Fertmann et al., 2004). And while more is being done the United States is far from coming up with a homogenous solution. The U.S. Environmental Protection Agency (U.S. EPA, 2011a), as directed by the Safe

    Lead is a naturally occurring element found in small amounts in the earth’s crust. Although it has some beneficial uses, it can be toxic to humans and animals causing health effects. Lead can be found in many places, much because of human activity through burning fossil fuels, mining, and manufacturing. Lead and lead compounds have been used in a wide variety of products found in and around our homes, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition, and cosmetics. When lead is released to the air from industrial sources or vehicles, it may travel long distances before settling to the ground, where it usually sticks to soil particles. Lead may move from soil into groundwater depending on the…

    Lead poisoning has been a concern for many years. In fact, because of the affects of lead poisoning, there has been an extensive decline in its use. "Many people believe lead poisoning is no longer a threat, yet millions of homes contain lead based paint" (Heck, J., 2005, para. 1). Exposure to lead at any level is unhealthy, especially in infants, children, and pregnant women and continues to be an ongoing dilemma in this country. I read two articles concerning lead poisoning; the first article is from FineTuning, a popular press and the second article is from Pediatrics, a peer-review journal. In this paper, I will clearly summarize each article by comparing the content of both articles. In addition, I will summarize the attention to details communicated in each article. Next, I will discuss the reasons for the research, who conducted the research, the methods used during the research, and the conclusions reached based upon the research. Finally, in this paper, I will discuss what I learned about peer-review journal articles versus popular press articles.…

    The lab was conducted at the McBride residence. For this experiment vegetable oil, vinegar and liquid detergent was use to contaminate the water. Testing of how ground water is affected by different contaminants was the bases of the experiment. The results were interesting in that when vinegar is filtered through dirt it came out fairly clean, it also changed the scent. This shows that maybe we can find a way to find a safer choice on how we filter and purify water. The use of sand, charcoal and gravel was used as an aquifer to exact the water. Bleach was used to sterilize the contaminated water and the process. For the last lab, tap, Dasani and Fiji water were tested with ammonia, chloride, iron and phosphate to determine which water is better for humans to drink. The results were that the vinegar changed the scent and the laundry detergent changed…

    The biochemical pathways of heavy metal poisoning are routes by which the metals pass in the body as they impair and destroy normal cellular and organ activity. The most common types of heavy metal poisoning are caused by lead, arsenic, cadmium and mercury. They are also the most extensively studied at the moment. Lead poisoning occurs mainly by the inhibitory effect that the metal imposes on enzymes and subsequent distortion of essential biochemical pathways. The metal disrupts calcium metabolism and subsequently causes neurotoxicity. It also inhibits the reduction of glutathionine in a biochemical process meant to produce antioxidants. Lead also intrudes and redirects the heme synthesis pathway leading to build up of aminolevulinic acid (ALA) in the cell. This results in the production of Reductive Oxygen Species (ROS) that mediate cell injury. Arsenic poisoning leads to the impairment of intracellular and intercellular communication pathways. Its effect on signal transduction leads to build up of free radicals that mediate cell death or injury. Mercury poisoning results from methylmercury. It has inhibitory effects that resemble those of lead and uniquely induces the release of free radicals in cells.…

    * With environmentalism and green thinking reaching the pinnacle of public appeal in recent years due to global warming, an increasing focus has been put on stopping pollution, especially carbon dioxide emissions. As such, the main battle has been waged against air pollution, while water pollution has not been in the public limelight. This does not mean that the problem is any less important, or any less pervasive however. Water pollution is caused by the release of any type of foreign contaminants into a body of water, or spilled in the watershed of a body of water. Perhaps the most common causes of water pollution are simply dumping of garbage and waste. Physical trash like cans, bottles, can rings, and the like commonly accumulate in bodies of water through littering. Worse still is contamination from bacteria, worms, and viruses present in sewage. Many undeveloped countries dumb sewage straight into rivers, lakes or the ocean. Industry also causes water pollution in the form of chemical runoff and spills, as well as heat, or thermal pollution, caused by allowing unnaturally heated water to enter natural bodies of water. Other toxic metals, salts and acids are dumped into water bodies from industrial processes.…

    Background: According to the Millennium Development Goals Report 2012, 783 million people, or 11 per cent of the global population, remain without access to an improved source of drinking water. Also the United Nations has long been addressing the global crisis caused by insufficient water supply to satisfy basic human needs and growing demands on the world’s water resources to meet human, commercial and agricultural needs (un.org). In this experiment water quality and contamination of groundwater was investigated. First, I observed the effects that many pollutants have on groundwater. I predict that in this experiment the oil and vinegar will create the large amount of contamination in the water, while the laundry detergent will just create an aroma smell to it. Considering the smells and color to these ingredients I think that it will cause the water quality to have a bad smell and cause the water to be very cloudy. Once filtering the contaminated water, the water will be clear and purified. Second, I will experiment water treatment and filtering. I predict that once the contaminated water is treated and filtered that it will leave me with less contamination or none at all. Then for the last experiment, I will determine the difference between bottled water and tap water to discover any contamination. I predict that the tap water will be the most contaminated and with the most chemicals in it, while the bottled waters; Dasani and Fiji will be completely filtered and free of any chemicals.…

    Water contamination is vastly becoming an alarming issue across the world. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution (www.nrdc.org). Clean and plentiful water is the cornerstone of prosperous communities. Yet as we enter the 21st century, swelling demand and changing climate patterns are draining rivers and aquifers and pollution is threatening the quality of what remains. NRDC is integrating our expertise in pollution prevention, water efficiency and climate change to sustain America's precious water resources, working to advance smart water efficiency policies to ensure that communities get the water they need while keeping our lakes, rivers, and streams full and healthy (www.nrdc.org).…

    Children in the country are being poisoned from lead painting used on homes, schools and other products. Lead is a toxic substance that is harmful to people for any age, especially young children. When the lead is absorbed into the body, it can affect their health systems and cause damage to the brain, vital organs such as nerves, kidneys and blood. Lead exposure may also cause behavioral problems, like learning disabilities and delayed people’s development. Lead in painting also used to create toys, it ends up into young children’s mouths and absorb lead in their bodies. According to the Department of Housing and Urban Development (HUD), “around 25% of the housing in the United States may contain lead paint in hazardous levels, every…

    Since we are dealing with children, we need to understand that they are at a higher risk than adults. Remember the saying “curiosity killed the cat?” (Martin, 2012) Cats are curious animals that like to investigate, but their curiosity can take them to places where they might get hurt. Children, like cats, are curious and like to products in their own dangerous ways. Children tend to be curious by touching items, putting them in their mouth, and sharing them with friends and family. This causes the levels of lead to rise along with the risk of lead poisoning.

    We have had the water of your village tested and found that the lead levels are at 22 ppb (parts per billion) which is a very high and deadly level for any drinking water. Pursuant to Environmental Protection Agency (EPA) regulation 40 C.F.R. § 141.80 (2007) the levels should be zero, but at bare minimum can be no higher than 15 ppb. As you can see by our test results you are well above this level and are putting the lives of your citizens at risk.…
