Polychlorinated biphenyl

PCB’s (polychlorinated biphenyls) and dioxins have been in focus recently as there are concerns that the different structures are appearing to mimic the effects of female oestrogenic hormones. (Gray 1996) These chemicals can cause genetic chromosomal problems and major concerns

#Introduction In modern society, people produce a significant amount of waste, such as agricultural, nuclear, solid, or electronic waste. While some waste goes to the landfill in the United States, some are exported to developed and developing countries. These exports include hazardous waste and harmless waste, in which some of the countries specialize in recycling them, but even so, there has been controversies about improper disposal of wastes in other countries. Exportation laws in regards to

Legally Poisoned: Lack of Environmental Protection in Communities of Color in the United States Eunyque Sykes The rapacious desires of nations to become wealthy led to the exploitation of Africa, the beginning of the Atlantic slave trade, and ultimately the independence and development of the United States of America. Europeans who cried for religious freedom and civil liberties from a tyrannous government ironically built a nation out of greed, aggression, and imperialism. As

For over two-thousand years philosophers like Hippocrates have studied behaviors characteristic of the psychiatric disorder known today as Attention-Deficit Hyperactivity Disorder, “ADHD” (Peterson, 2007, p. 10). It is defined by Myers (2010) as “a psychological disorder marked by the appearance by age 7 of one or more of three key symptoms: extreme inattention, hyperactivity, and impulsivity” (p. 595). ADHD is predominately seen in boys. Possible reasons for developing this disorder have been

Chesapeake Bay Television commercials, print ads, and billboards in the Washington, DC, area are asking residents to connect two things many might find unrelated: lawn care and seafood. In one commercial, a man stuffs a big plateful of grass in his mouth after a voice-over says, “Spring rains carry excess lawn fertilizers through our sewers and rivers and into the Chesapeake Bay, where the blue crab harvest has been extremely low. So skip the fertilizer until fall, because once they’re gone, what’s

Plastic in the ocean A large number of marine species are known to be harmed and/or killed by plastic debris, which jeopardize their survival, since many are already endangered by other forms of anthropogenic activities. Marine animals are affected through entanglement in and ingestion of plastic litter (Marine Debris). Less conspicuous forms, such as plastic pellets and “scrubbers” are also hazardous. To address the problem of plastic debris in the oceans is a difficult task, and a variety of approaches

pollutants are chemical compounds that contain carbon and have a negative effect on one or more components of the environment. From 2011–2015, EAD monitored marine waters for two organic pollutants: total petroleum hydrocarbons (TPHs) and polychlorinated biphenyls (PCBs). TPHs is a term used to describe a mixture of several hundreds of chemical compounds that are derived from crude oil. Measurable background concentrations of TPH can be a result of excess oil contamination or in some cases the result

Ecosphere versus Technosphere Commoner believes humans live in two worlds: the ecosphere world and the technosphere world. Ecosphere is referred to as the physical, biological, and chemical processes that occur naturally, such as storms, droughts, and floods. The technosphere world is a man-made creation that helps us to survive within the ecosphere. These creations include technology, homes, factories, laboratories, music, art, etc. According to Commoner (1992), we accept responsibility for events

MA# 3: Is Storm Water Damaging the Puget Sound? Today, storm water runoff is the number one cause of pollution in the Puget Sound. The pollutants contained in storm water runoff are mainly caused by urban runoff, factory farming, and chemicals. Urban runoff can produce pollutants such as gasoline, grease, ammonia, manure, toxic chemicals, and pesticides. In factory farming, the main problem is the production of manure which is extremely bad for the Puget Sound because of the high levels of nitrates

Many consumers today are confused about the controversy about fish and its health effects. Researchers have discovered that fish contains methyl mercury, polychlorinated biphenyls (PCB), and dioxins that may put one’s health at risk (“Harvard College”). The industrial processes cause mercury to be released into the air, then the chemical ends up in the lakes. Therefore, the contaminants come from bacteria that live in lakes that are then absorbed in species. When people consume fish, they are also
