"BIOLOGICAL TREATMENT OF MERCURY WASTES
Introduction. It would seem paradoxical that biological systems could be put to useful work treating as toxic a substance as mercury. But in limited ways and degrees this has occurred, and the successes are reviewed here.
Theory of Mercury Transformation Process(es). "Perhaps the most toxic metals are the nonessential metals such as cadmium, lead, and mercury" (7:318). Some microorganisms that encounter these metals have developed strategies to prevent entry of them into their cells or literally to pump them back out again: sequestration, active transport, or chemical transformation (7:319). The last of these (oxidation-reduction reactions) is used to reduce the mercuric ion, Hg+2 [also written as Hg(II)] to elemental, metallic mercury, Hg0, which is volatile and can thus ..."

Abstract
This paper discusses the chemical properties and uses of mercury. It particularly discusses the medical uses of mercury and then goes on to describe the concerns of using mercury for medicinal purposes. The paper discusses the fact that government regulatory agencies are being pressured into loosening mercury pollution controls, despite the fact that history and science have shown the risks of mercury poisoning. The paper concludes by discussing the possible link between mercury in childhood vaccinations and the development of autism.
From the Paper
"Thimerosal, or thiomersal, is an organic compound containing mercury, that is used as an antiseptic and antifungal treatment Originally trademarked under the name Merthiolate in 1929, it has been "used as a preservative in vaccines, immune globulin preparations, skin test antigens, antivenoms, ophthalmic and nasal products, and tattoo inks." (Wikipedia 2006c) Most childhood vaccinations not longer contain thimerosal, and are instead stored in single-dose vials that do not need the same preservatives added. It was first used as a bactericide in vaccines in the early 1930s, and by the mid 1980s it was used in the vast majority of vaccines. In 1999, the American Academy of Pediatrics requested the removal of thimerosal from all pediatric vaccines. Today, thimerosal is still used in a few United States vaccinations, and "The World Health Organization, with US funding, is providing thimerosal-containing vaccines (TCVs) for children in developing countries with the same amounts of thimerosal, as were given American children at their peak exposure levels." (Wikipedia 2006c)"

Abstract
This paper traces the origins and history of biological weapons, especially in the United States. In knowing its history, this research also looks into the development of technology as one of the precursors that helped ?develop? and proliferate the creation of microorganisms that can destroy not only the human body, but the Earth?s physical environment as well. Furthermore, the use of biological weapons as an alternative for weapons in the act of terrorism and as a means to destroy another nation or society is also studied and analyzed, thereby putting the production of biological weapons in its socio-political context. Classifications of biological weapons presently produced are also identified. Lastly, measures and policies formulated to encourage and promote non-proliferation of biological weapons, a socio-political issue, is also tackled.
From the Paper
"The origin and history of biological weapons can be traced as far back as the 14th century, where plague epidemics become biological weapons used by conquerors in order to easily overpower other nations/societies. In American history, biological weapons use is evident in the use of the smallpox disease as a way for the French and British forces to defeat the Native Americans, original inhabitants of the US territory, in the 18th century (Lederberg, 1999:18-9). Biological weaponry has become more developed in the 20th century, during the First World War, when Germany used ?wind-blown chlorine? as a weapon to physically weaken the enemy?s army forces. Germany?s use of chlorine later developed to phosgene to mustard gas, attacking the skin and lungs of its victims, proving itself to be a pervasive form of biological weapon, since gas masks proved to be ?ineffective? protection to this biological weapon (Falkenrath, 1998)."

Abstract
This paper looks at whether or not mercury poisoning causes malformations in young children. There is some evidence for brain damage in fetuses from mercury which crosses the placenta and the blood-brain barrier, but there is no conclusive evidence on malformations caused by mercury poisoning. Mercury is a neurotoxin, so most of its affects are within the nervous system.

Abstract
This paper examines various sources of mercury pollution and debates options for addressing the problem. The paper further discusses the various ways that mercury pollution takes place and the role the government should take to combat the dangers of mercury pollution.
From the Paper
"Mercury has been found to be one of the most toxic substances in our environment today and yet little has been done to stop its contamination of our air and water. Some sources advocate retiring mercury i.e. making it illegal to sell mercury. Since pollution of our air and water contaminates our food supply as well, it is also argued that we need to stop selling fish captured from the open sea and sell only fish that have been cultured in..."

Abstract
This research paper, entitled "The History and Use of Biological Weapons," provides an overview and discussion of how biological weapons are used by terrorists and war-makers. The paper includes some examples of how they have been used in the past, how they could be used in future attacks and an assessment of the ramifications of their use. The paper explains the science of the biological weapons.
From the Paper
"Even though the use of biological weapons has been a fairly recent phenomenon, the direct use of biological warfare against enemy personnel is very old. Today, however, the use of biological weapons such as anthrax in our country?s mails has received enormous levels of attention because of its direct impact on the nation and on each of us as potential targets. That is what makes it such an effective terrorist tool, but overall, biological warfare is tricky stuff indeed -- just as likely to kill the bearer as the intended recipient."

Abstract
In this article the writer discusses that, throughout time, the quest to dominate another is limited only to the imagination of one man poised against the other. The writer points out that sometimes common flu symptoms such as headache, dizziness, nausea, vomiting, coughing, and shortness of breath are the first signs of chemical and biological warfare (CBW). The writer maintains that for some reason, the more one searches for answers to counter the effects of CBW the worse it gets. In this essay, discussion centers upon the 1972 Biological Weapon's Convention and the Geneva Protocol. The writer focuses on scientific research in this regard and identifies several items that are being used to help detect biological and chemical agents.

Chemical Agents and their Effects
From the Paper
"Throughout history, chemical and biological weapons (CBW), warriors and terrorists have used a wide range of tactics and techniques to help defeat their enemy on and off the battlefield. These weapons are used in war to gain the upper advantage against a more formidable adversary, to enhance the political status of a rogue terrorist group, or to cripple the economy of a nation from the simple mailing of a threatening letter with powder. Whatever the reason, the unknown effects of a release can be devastating. Law enforcement personnel who respond to the initial crisis of a release or assist with the aftermath have to know the difference between a chemical and a biological agent release. These weapons of war also have evolved from throwing rocks and sticks at each other to the unthinkable weapons of mass destruction called bioterrorism. You may ask yourself, what is bioterrorism? The Center for Disease Control defines bioterrorism as the intentional or threatened use of bacteria, fungi, or toxins from living organisms to produce death or disease in humans, animals, or plants and involves intimidation of nations or people to accomplish political or social ends."

Abstract
Discusses the serious problem of mercury pollution. Dangers to children and the developing fetus. Industrial air pollution as the major source of mercury pollution. Power plants and automobiles as other sources. Growing problem of mercury polluted waters on fish and humans who eat fish. Lack of effective treatment. Control measures.
From the Paper
"Summary
Mercury toxicity is a serious problem since mercury does not degrade in the environment and so once it is there as a contaminant, it is difficult to remove. It is highly toxic, particularly to children and the developing fetus, where it interferes with development, particularly the maturation process of the brain. Whatever form mercury is in - elemental, inorganic, or organic - it is toxic, and there is no truly effective treatment once it gets into the human body. Chelation therapy may help, but there are doubts as to its effectiveness or its ability to reduce the toxic effects which may have already occurred.
Most mercury pollution comes from industrial air pollution, although more and more water is becoming polluted from industrial ..."

Abstract
This paper explains that mercury preparations and compounds are a vitally important component of U.S. production in a wide range of industries, but its use carries with it some known health and environmental risks. The author points out that the coal, agricultural and healthcare industries, which use mercury compounds, are most likely in favor of the legislation because of a lack of a suitable alternative. The paper recommends that the U.S. Senate support the proposed legislation because it represents a viable approach to moderating the impact of mercury emissions across the board, provides those industries that are not currently able to achieve EPA standards with the opportunity to improve and is cost advantageous.

From the Paper
"How is this proposal likely to play out in the press? Clearly, this is an emotionally charged issue that is fraught with opportunities for misunderstanding among the public, and these misperceptions about the safety record and importance of mercury in many industrial applications may be overlooked. There is, in fact, valid reason for concern. According to Stadler and Murray, during a 12-month period beginning in 2000, several major developments in mercury-related industries emphasized the need for oversight in order to eliminate mercury pollution and exposure in the United States."

Abstract
This paper surveys the relevant evidence suggesting that the United States helped Iraq acquire biological agents. The evidence pertains to major claims about the United States and Iraq during the Iran-Iraq War. One is that the United States ignored signs that Iraq was using biological weapons. Another is that the United States directly sent samples of biological agents to Iraq. The paper then surveys the events in question chronologically, by evaluating the evidence and ascertaining when the alleged events took place, within the context of the Iran-Iraq War.
From the Paper
"Whether the US aided Iraq in obtaining or producing biological weapons is controversial. Over the years, many people have pointed out the irony that the United States helped arm Saddam Hussein in the Iraq-Iran War, and that this has come back to haunt the government. It is clear that the United States supplied military assistance in various forms during the Iran-Iraq War; that is not in question. However, whether the United States played a role in or facilitated Iraq?s acquiring or producing biological weapons is more controversial. The evidence suggests that the United States played some sort of role in helping Iraq acquire biological agents and ignored their use of chemical weapons, but there is no evidence that the United States helped Iraq create or acquire actual biological weapons."

Abstract
This paper looks at how September 11th brought a greater public awareness of biological weapons and the threat they can pose to world populations. The paper also explains what biological weapons are and why they can be so effective, discusses their history and the dangers they pose, and looks at what we can do to protect ourselves from their devastating effects.
From the Paper
"The terrorist attacks of September 11 played a crucial role in awakening the world to the possibility of advanced warfare. Before this tragedy, the world could hardly imagine that our good old airplanes could actually be used as missiles to kill ten of hundreds of unsuspecting souls. But September 11, proved that terrorists were far ahead of the intelligence agencies and the general public when it came to designing and deploying sophisticated war tactics. War for a terrorist need not involve the military or military tactics of any nature; it is simply a conflict where the side with best strategies and most unique weaponry stands a better chance of emerging victorious. It appears that United States and the entire world was largely unaware of this perspective on war and thus underestimated the intelligence of terrorist groups since they merely focused on conventional ways of securing the nation that had little or no protection to offer against advanced terrorist tactics and strategies. However September 11 was a big eye opener, not only did it divert the attention of the public and government to the horrific nature of new terrorist strategies, it also opened their eyes to the possibility of chemical and biological warfare that had hitherto been ignored as nothing but science fiction."

Abstract
This paper examines chemical and biological weapons, by defining them, defining their use in past wars and their use today. It illustrates the repetition of history in the correlation between historical use of mass destruction weapons and today. The paper uses Vonnegut's novel "Cat's Cradle" as an example to poses a scenario in which an ultimate chemical weapon (ice-nine) is used on soldiers. The paper shows that the greed in the novel results from the creation of chemical and biological weapons, which threaten to tear apart the world, which it eventually does, leaving a barren frosty wasteland.
From the Paper
"For the last century, the use of chemical and biological weapons has stood in the back of people?s minds as an impersonal and distant horror. This is especially true in the United States, which did not see the poisonous clouds over its battlefields or the sight of businessmen choking to death on its subways like Europe and Japan did. This has changed in recent times, with cases of anthrax continuing to arise from within the bounds of America. Though this danger of chemical and biological weapons is not anywhere near the proportions seen in the novel Cat?s Cradle, by Kurt Vonnegut, it has shown Americans that the threat and destructive power of chemical and biological weapons is valid. Now more than ever it seems that more measures need to be taken to stop the production and use of deadly chemical and biological weapons."

Abstract
This paper analyses how anthrax is a powerful biological weapon, which when used appropriately, may result in the death of thousands or even millions of people. It examines how, in order to maximise the efficiency of a response to a bio-terrorist attack involving anthrax, wider knowledge of the microbiology and spore formation of anthrax is needed, as well as effective biological counter measures to ensure the safety of civilian populations.

From the Paper
"Releasing anthrax would be relative simple, a cloud of anthrax spores released in a strategic location, with a high civilian population, could kill thousands or even millions of people if released according. A lethal dosage of anthrax is considered to be 10,000 spores; 80% of a population that inhaled such a dose would die. Less than one millionth of a gram is invariably fatal within a couple of days after exposure. (REF) An anthrax aerosol would be odourless and invisible following release and would have the potential to travel many kilometres."

Abstract
This three page graduate paper examines whether gender is a social construction or a biological outcome. Viewing the film, 'Ma Vie En Rose' and studying assigned readings helps the writer to examine the influence gender has on shaping human behavior. The writer points out that these sources indicate that both social construction and biology influence gender perceptions and behavior.
From the Paper
"In determining whether gender is a social construction or a biological outcome, viewing the film, Ma Vie En Rose and studying our assigned readings have been helpful, for they examine the influence gender has on shaping human behavior. These sources have indicated that both social construction and biology influence gender perceptions and behavior, and that outcome is generally determined by the degree of social construction applied in each child's case. "Social learning theory proposes that associations found between parental behaviors and child outcomes are primarily due to parents' socialization of the child through a system of rewards and punishments"."
