Bioaccumulation and Biomagnification: Minamata Disease History of Minamata Disease. In 1908 the Chisso Corporation, a major chemical manufacturer in Japan, opened a nitrogenous fertilizer factory in the small fishing town of Minamata (figure 1). Over time the corporation chose to branch out and began producing other chemicals such as acetylene, acetic acid, vinyl chloride and octanol. The waste product from these chemicals was released into Minamata Bay via the factories wastewater system, causing

The Minamata Disease as an Example of Government Weakness The effects of Minamata disease, which originated in Minamata, Japan, first came to the attention of local fishermen. They referred to cats afflicted with the disease as “the suicide-prone group of dancing cats” due to their tendency to ‘dance’ around, and then jump into the nearby bay (Ui, 1992). From 1940 through the late 20th century, thousands of inhabitants of Minamata developed that same neurological disease that resulted from

The Minamata Bay incident also known as the Minamata disease was the largest and most tragic case of industrial pollution to be recorded in history. In the late 1950’s, the consequences of dumping methylmercury into the ocean from the formation of acetaldehyde was not taken into account by the Japanese authorities of the Chisso Corporation chemical factory at that time. As a result, the methylmercury infected water was taken up by the marine life and caused major food poisoning when consumed by the

A blessing or a curse, you deside. In the next 20 years British Columbia's population is expected to flourish by approximately 40% and the power use is expected to expand by 50%. With the expected demand in power many have turned to the Site C Dam as an easy out. This project would be built on the Peace River and it would be the third dam on the river. This project is so big it would cost 7.9 billion dollars. Many would benefit from the project, but the same breath many would have a great deficiency

Mercury: A toxic poison No other metal better illustrates the diversity of effects caused by different chemical species than does mercury. On the basis of chemical speciation, there are three forms of mercury: elemental, inorganic, and organic compounds. The major source of mercury is the natural degassing of the earth's crust, including land areas, rivers, and the ocean, and this source is estimated to produce on the order of 2700 to 6000 tons per year. The total man made release into the

Today when people think of heavy metal, they think of numerous rock bands such as Guns n’ Roses, AC/DC, or Led Zepplin. However the more health conscious person should think of heavy metals such as lead, cadmium, and mercury. The most common metal to come in contact with humans, with possibly the most serious effects, is mercury. Mercury is a natural substance that can be found in the environment. It is the only common metal that is a liquid at room temperature, but at high temperatures it can evaporate

Mercury in the Everglades Everglades Background Information: * Established in 1947 on 1.4 million acres in southwest Florida * Sunny, Semi-Tropical Swamp Setting. Experiences near daily downpours (http://srv3sftpa.er.usgs.gov/sofl.fact.html) Mercury's Effect on the Everglades: * A small amount of mercury is found in the crust of the earth. This is not the problem. The anthropogenic mercury is the problem. The mercury that is growing dangerously in size is known as methylmercury

Mercury Pollution Imagine that every fish you have been eating and every fish on the market is contaminated with mercury; would you want to take action to improve this situation in order for yourself and everyone else to have healthy fish to eat? Most of the fish today are exposed to mercury, and mercury toxicity threatens the health of everyone who eats fish. Mercury pollution has been a well known ocean pollution for many years, and United States remain to be one of the top nations with the most

Animals have been on the face of the Earth since the beginning. Different cultures praise them as Gods or consider them sacred. But as the years drag on, people disregard animals and put them to the curb. In America, research labs on college campuses and across the country are performing vivisection. Vivisection is when millions of "animals are dissected, infected, injected, gassed, burned, and blinded" (IDA). In Africa, poachers kill elephants only for the ivory from their tusks. Not only does cruelty
