The land has seen the involvement of the Environmental Protection Agency, the Leech Lake…
Unethical Study: Tuskegee Syphilis Experiment In the early century, many individuals across the world have endured several disgraceful and horrific unethical experiments from trusted doctors and scientists, especially the unforgettable experiment of Tuskegee Syphilis in Macon, Alabama. The study was authorized by the United States Public Health Service and supported financially with tax payer’s dollars and controlled by government physicians. In 1932, Macon was a poor county filled with African Americans who were afflicted by several kinds of illnesses.

Before the Toxic Substances Control Act was passed by the United States law in 1976, the human population was believed to have been exposed to a multitude of chemical substances and mixtures. These chemicals were beginning to cause a lot of health problems to humans. This caused the lawmakers to believe that among the substances that are being constantly developed and produced, there are some whose manufacture, processing, distribution in commerce, use or disposal may present an unreasonable risk of injury to health or the environment. So, they had to act before these chemicals ravished humanity. The law gave power to the Environmental Agency Protection, otherwise known as EPA, to track the industrial chemicals that were being produced or imported…
Furthermore, Astarte exists as the Greek name of her counterpart Ishtar of the Akkadian, Babylonian, Assyrian, Semitic people of Mesopotamian; Astarte also became worshipped in Egypt and Syria, among the Hittites, as well as in Canaan. She became assimilated with the Egyptian deities Isis and Hathor; and in the Greco-Roman world with Aphrodite, Artemis and Juno. Decisively, Hebrew scholars now feel that the goddess Ashtoreth referenced oftentimes in the Bible exists as an intentional alternate for the Greek name Astarte. As one can determine, the intertwining of the goddesses overlaps one lustful deity after the next; virtually, intermingling them indefinitely. The Decline of the Great Goddess…
Platinum(symbol: Pt) is a very useful, but rare, element. The name Platinum comes from the Spanish word "Platina" meaning silver. Platinum is sometimes called a "Noble Metal" because of its unreactiveness to other elements including Oxygen. Because it is so unreactive, Platinum is commonly used for jewelry, dental filling, surgical tools, and laboratory apparatus. In normal conditions Platinum is a solid, shiny, silver metal. Its atomic number is 78, and its atomic mass is 195.084.…
Mercury contamination of aquatic ecosystems is responsible for X% of all fish consumption advisories in the United States (cite), and negatively effects beneficial uses and ecological health of aquatic resources globally (cite). The global prevalence of Hg contamination is at least partially attributable to the 3-5 fold increase in atmospheric Hg concentrations over the past 150 years associated with fossil fuel combustion (cite), as well as regional and local releases from mining and industrial applications. However, temporal patterns of Hg concentrations fish and aquatic birds that are consistent with the increases documented in abiotic matrices have not been realized. Instead, a range of trends have been detected, including increases (cite),…
Many chemicals are safe to handle but negatively impact the environment in the long run. Other chemicals such as arsenic are toxic even in the smallest amounts. Mercury is a natural element that occurs throughout our environment and solar system. It has unique properties (i.e liquid metal at room temperature) and can be found in very small concentrations in many rocks and is the main component of the mineral cinnabar. Natural background levels can be detected in soils, living organisms, air, and water around the world.…
Hypogonadism after iron chelation therapy and bone marrow transplantation In chronic iron overload, when transferrin is completely saturated, NTBI is found in the plasma, which is the form of iron that causes toxicity. Intensification of chelation therapy has been shown to reverse cardiac structure and function, but not in the liver. The mechanism proposed was that the heart and also endocrine tissue, including the pituitary gland, take up circulating labile iron species that are non-transferrin-bound iron, while liver iron uptake is mediated via transferrin. Chelation therapy with desferoxamine before the age of puberty has helped patients to attain normal sexual maturation in some studies but not in others.…
Abstract Water treatment methods were recorded as early as 4000 B.C. It was not till the early 20th century that chlorination was implemented to distributing water systems in the U.S. Today, chlorination remains the most widespread method of purifying drinking water. Chlorine has eliminated waterborne diseases like cholera, typhoid and dysentery. It also eliminates slime bacteria, molds and algae that grows in water supply reservoirs.…
Lipstick and Lead Poisoning Throughout history many unhealthy substances, including lead, have been used as ingredients during the various times in the history of makeup. Modern day cosmetics are more controlled, regulated and their ingredients and the potential side effects are more fully understood. However, recent research by the Campaign for Safe Cosmetics and the Food and Drug Administration (FDA) indicate that there are approximately 400+ best-selling lipsticks on the market today that have tested positive for lead. There is no safe dose for lead exposure based on these recent science studies.…
