Alongside the goals of the EHAP, the Sapperton Fish and Game Club (SFGC) has contributed to the restoration of habitat in the Brunette Basin Watershed and the reintroduction of salmon into the Brunette River. The SFGC played an important role in coercing Metro Vancouver to avoid using chloramine (a chemical that is harmful to aquatic animals) to sanitize drinking water in 1992 (Sapperton Fish and Game Club [SFGC], n.d.). The SFGC has also acted as stewards of the Brunette River by operating a salmon hatchery since 1997 that breeds salmon that are eventually…

The purpose of this paper is to reflect on Sandra Steingraber 's book, Living Downstream: An Ecologist Looks at Cancer and the Environment. I will examine Sandra Steingraber 's compilation of scientific studies that link environmental pollution, contamination and toxicity to various types of cancers in humans and in animals as well. I will also discuss my personal opinion of the book, how my thinking and perspective has changed as a result of this book, and the importance and value of educating oneself by reading books such as this.…
2) a) The accepted toxicity varies from metal to metal. The accepted toxic level of lead is 0.0012 parts per million, however it is not considered safe at any level. The environmental protection agency says that the maximum contaminant level for cadmium in drinking water is 0.005 mg/L. In soil it is said that the highest amount of cadmium that can be accepted in land is 85 mg/kg. For Mercury the accepted toxic level in aquatic systems in 1ppb…
1. Is Mercury a good target for AGI? Discuss strategic fit of brands, products, customers, and distribution. Identify specific sources of value. Discuss AGI’s strengths/weaknesses compared with other bidders.…
At 94, years old John Glenn still has the “right stuff”. In 1959, John Glenn rose to fame as part of the Mercury 7, a group of 7 men picked to be America’s first astronauts. The Mercury 7 were as popular as movie stars are today. John’s flight on the Friendship 7 mission on February 20, 1962, gave him the title of being the first American to orbit the Earth and the fifth person in space. John became a national hero. John is the last living astronaut of the Mercury 7 and I sat down with him to discuss all of his accomplishments over the past years of his remarkable life including his life after NASA as a U.S. Senator.…

The people in surrounding communities, the wildlife habitat, and the river water quality. The Ohio River community needs to be more informed and aware of the toxins in the Ohio River in order stop this devastating problem.…
Toxic Contaminants are substances that can harm sea and human life. They come from human causes such as fertilizers, and other pollutants that humans use to decontaminate land plants. Many of these toxins are so strong that despite being consumed by wildlife and fish, the poisons tend to not break themselves down. That means, a toxin that went from fertilizer in a yard, can be a poison to a fish a human can eat, and therefore can affect people more than they…

The statement that dredging is harmful to drinking water backs up the authors claim that dredging stirs up mercury that has settled in California’s waterways as a consequence of historic mining. Mercury is a naturally occurring metal from Cinnabar. Mercury has a density of 13.5 where Gold has a density of 19, this density or weight is used to keep heavy metals in a sluice box. The US Geological Survey Study performed in 2010 could not find any trace emissions of mercury from a running dredge, using test equipment measuring in parts per trillion (Monde Labe, 2012). To further back up the fact that dredging removes mercury from waterways, the Environmental Protection Agency (EPA) along with California 's Division of Toxic Substance Control worked together In August and September 2000 and conducted the first mercury hazardous materials turn-in where they collected 230 pounds of mercury (Environmental Protection Agency,…
Rainwater also carries contaminants like trash, car oil, and animal fecal waste from the streets and roads into the storm drains (“Stormwater Runoff”). All of these pollutants also eventually lead into the Bay. Many of the aquatic organisms may be intoxicated or trapped by the oil and trash. This will lead to the depletion of their populations and consequently affect the other organisms in their food chain, and the humans that rely on them as a source of food (“Stormwater Runoff”). The chemical contaminants affect the population of all sorts of aquatic life in the Chesapeake Bay. For example, the “small bottom dwelling organisms take in the contaminants through skin contact while feeding” (“Chemical Contaminants”). Larger fish then consume the chemically contaminated fish, and accumulate the toxins in their body tissue (“Chemical Contaminants”). Mammals and other wildlife then consume these contaminated fish as the chemicals keep harming the predators of contaminated prey in the food chain (“Chemical Contaminants”). Many Marylanders rely on aquatic organisms, like crab, that they fish from the Chesapeake Bay as a source of income. If the pollution of the Bay is not stopped, the disappearance and contamination of these organisms will bankrupt many entrepreneurs in the state. These aquatic organisms will not be able to survive from the continuous exponential growth of toxins in their ecosystem.…
Pollution causes chronic illness, neurological damage and shortened lifespan. For instance, the presence of lead in children lowers I.Q. by an estimated 4-7 points for each increase of 10 μg/dL.3 Our database identifies populations around the globe with blood lead levels ranging from 50 -100 μg/dL, up to 10 times the WHO reference levels for protection against neurological damage.…
John Dutton’s essay “Toxic Soup” (2006) speculates about the effects that humans have on pollution in the ocean, as well as ways the damage can be reduced. In this essay, Dutton incorporates his personal experiences as a surfer and nature lover with statistics and his knowledge of the effects of water pollution on animals and humans. Dutton’s purpose is to raise public awareness of the need for environmental protection of the ocean in order to preserve and improve nature’s status. Given the language and references used, Dutton is writing for college educated adults interested in science and the environment.…
