Analyzing the Science

Credibility material: Since the assignment of this project, our group has been reading articles from Chicago newspapers, blogs, news stations, and government agencies.

b. In your opinion, which organization has the greatest potential for bringing about positive change? Why?

To be reliable means to be dependable. For a website to be reliable, it needs to present facts or issues in an unbiased manner; we need to be able to depend on the information found on the site. Some websites are better at that than others. Martin Luther King, Jr.: A True Historical Examination looks like a reliable resource for students researching Martin Luther King, Jr., but the site lacks the objectivity of a similar site, the Seattle Times’ website, Martin Luther King Jr. and the Civil Rights Movement, making it unreliable.

Also depicted in this paper is the type of cancers caused by each chemical and other related health problems associated with each chemical. Finally, the role of government agencies such as FDA, EPA and OSHA in preventing excessive amount or zero amounts of toxic chemicals from entering the environment will be discussed. The last paragraphs will enumerate the inferred conclusion from my research on Agent Orange, DDT and Benzene.

The information given to people seems credible because it is the only familiar source. Any other

The purpose of this course is to provide the fundamental knowledge of the effects of environmental chemicals on living systems, and the toxic responses of the human and plant systems. Students will discuss risk, ethics, and social responsibility with regard to environmental toxicology.

River water near the spill showed elevated levels of lead and thallium, Mercury and arsenic cadmium and lead exceeding Clean Water Act standards designed to protect aquatic life as well as humans who come in contact with the water. Which can cause birth defects and nervous and reproductive system disorders?

He explains that the recommended level of mercury is .4 ppm (parts per million). However, the piece that he measured had 2000 ppm of mercury. That is 5000 times higher than the levels deemed to be safe for eating. Even though this meat exceeds the regulation requirements for mercury, it is still allowed to be sold without the public knowing. The movie goes on to explain what exactly mercury can do to a person by bringing up an event that happened in Minamata, Japan. There, a factory was dumping waste into the local water source and polluting it with toxic levels of mercury. The people who were most affected were the pregnant women’s fetuses; they were most susceptible to the toxins, and contracted what the locals called Minamata’s disease, or extreme mercury poisoning. These children were born with major birth defects, such as blindness, lack of motor control, muteness, and deafness. For the longest time, though, no one knew why this was happening. They did not know where it came from. Studies carried out much later revealed that it was in fact high levels of mercury that had poisoned the region’s

C. Credibility: As a fan of comic books and movies, I have always been interested in the dynamics and history of the Marvel and DC companies.

d. Does the firm appear to have an effective corporate governance structure? Explain any shortcomings.

Credibility: I am a credible source for this topic through all of the research I have found.

Mercury contamination in aquatic environments is becoming an increasing threat to both wildlife and humans (Peterson S. A., 2007). Organisms in the aquatic environment, particularly fish, bioaccumulate methylmercury from contaminated water and food, but predominately from food (Peterson S. A., 2007). Mercury in the atmosphere exists in three inorganic forms: gaseous elemental mercury (GEM: Hg0), oxidized mercury typically called reactive gaseous mercury (RGM: Hg2+), and particulate mercury (Hgp) (Hyun-Deok Choi, 2008). Once emitted, mercury can be transformed from one species to another via photoreduction, reactions with halides, and other oxidation/reduction reactions (Hyun-Deok Choi, 2008). Methylmercury is the bioavailable form of mercury, with well-documented adverse effects (Rimmer, 2010). Methylated mercury is known to cause adverse effects to wildlife and aquatic organisms. Methylmercury can have neurotoxic, immunotoxic, and developmental effects on fish, birds, and mammals; top consumers may be at elevated risk (Weir, 2010). Methylmercury is synthesized from inorganic mercury (Hg II) by aquatic bacteria at oxic/anoxic boundaries such as sediment-water interface of lakes and rivers (Hurley JP, 1995). The degree to which an aquatic system is impacted by methylmercury contamination is a function of a number of factors, including the rate of supply of atmospherically derived Hg (II), the net rate of mercury methylation by aquatic, the efficiency of transport and

The people with the most risk of damage by mercury are unborn fetuses and children. Studies seem to show that the metal

People can come in contact with mercury in a number of ways. There is increased risk of mercury exposure in the dental, health and chemical industries. People are also at risk of consuming an unsafe amount of mercury if they eat certain things in excess amounts, such as more than 6 ounces of albacore tuna per week, or over 12 ounces of fish like shrimp, canned tuna, salmon, pollock or catfish. Exposure to mercury can cause brain damage, kidney damage, lung damage and various digestive system problems (McCoy). Perhaps the person most vulnerable to mercury poisoning is the pregnant woman and her unborn fetus. Trauma caused to infants and children as a result of
