Soil contamination

It is becoming evident that humans are continuously exposed to a plethora of chemicals from food, medicinal agents, occupational activity and contaminated sites. Exposure to chemicals begins in utero and continues throughout life. Toxicological risk assessment of individual chemicals provides the quantitative estimate of its possible effects on human health. When humans are exposed to chemicals, they are not exposed to a single chemical only, but simultaneous or sequential exposure occurs to a…

1. There is a disconnect between Odwalla’s corporate social responsibility model and its actions. Odwalla’s motto of “soil to soul” metaphor stated that is used fresh organic fruit to nurture the body whole of its consumers. Odwalla produced organic fruit juice by using an acid-based rinsing process to killer bacteria instead of pasteurization because they believed it affected the taste of the juice. However, Odwalla’s actions were not socially responsible when they found out that the U.S. Army…

29). RBCA may allow contamination to stay in place as long as it remains under certain threshold levels. However, “the state may require engineering controls as well as ongoing sampling and monitoring activities” (Haight, 2012, p. 29). Remediation “A determination must be made based on the impact of contamination levels at the site. RBCA allows the state to establish limits of contamination for specific chemicals/contamination that has a limited threat to human health and…

The reason TYMC is such a crucial factor is because mold and yeast are considered members of the fungus family. It can be found all throughout nature, in air, soil, water, vegetation and decay. It can grow and thrive in a wide range of temperatures and pH environments, even in harsh conditions that bacteria would not be able to survive in. Unlike plants, they do not produce their own food source. Their means of survival consists of breaking down matter from their immediate environment into…

elsewhere. As this can get expensive, hydrologists look for various alternatives. About 50% of the United States drinking water comes from groundwater wells. Contamination in such wells has become a major problem for those who do not have much of a choice to where they get their water supply. Hydrologists now have the tools to locate contamination, but as this is costly. Extracting contaminants from groundwater is important, but taking the necessary precautions and making sure you are not the…

the macaques and the toxic chemicals are disposed of which lead to air, water, and soil pollution (Groff et al, 2014). Because of a large amount of energy that is required to keep the environment “liveable” for the animals, it demands a large supply of fresh air which causes carbon emissions. Improper disposition of chemical wastes leads to soil contamination by increasing the level of the toxic chemicals in the soil (Groff et al, 2014). The toxicity testing that eventually…

that antibiotics have harmful side effects on the environment. When animals are administered antibiotics, it kills off other bacteria and allows antibiotic resistant bacteria to survive and multiply. This causes contamination of animal waste, which then comes into contact with water, soil, or air (Food, Farm, Animals, and Drugs 2014). Horizontal gene transfer is also a big concern for the environment. In recent years, there has been an increase in antibiotic resistant bacteria found. The…

The Chernobyl Catastrophe and its Impact on the Environment Imagine New York City, a city bustling with life; busy streets, people flooding the sidewalks, flashing lights, and never ending noise. Now imagine a post-apocalyptic city; deserted streets, empty buildings, shattered windows, doors hanging from their hinges, weeds and overgrowth climbing up walls, and unsettling silence. This is how one may describe Pripyat, Ukraine. What was once a city filled with great activity and energy is now a…

Chemical contamination refers to the contamination of the environment with chemical substances, there are many chemical contaminants, and some of them are volatile found in our environment. Benzene is one of them, it evaporates rapidly, it smells sweet, flammable, colorless liquid, it presents in gasoline, crude oil, and cigarette smoke. Benzene is one of the chemical contaminant which used in manufacturing many products like plastics, synthetic fibers and resin. Also, it is used to solve waxes,…

food products, needles and chemicals with unknown dangers. As someone who is considering a career in the field of medicine and research, I believe that we are responsible to find alternative methods to animal research and testing to reduce the contamination of our ecosystem. According to Dr. Appolloni , one of the major problems that we are facing today in…
