Essay On Arsenic Estimation

1799 Words8 Pages

Elements generally occur in their natural form in the Earth’s crust, some important micronutrients while many being absolutely toxic. Arsenic is the twentieth most abundant element and the inorganic form is the most toxic in comparison to certain organic compounds like arsenobetaine and arsenocholine which is tolerated better [1, 2]. In India, cases of arsenic toxicity has been reported mainly from West Bengal and also rivers like Ganga, Bramhaputra, etc. [3]. Groundwater contamination by arsenic continues to remain the major source of exposure in the country leading to cases of chronic arsenic toxicity. Projects on groundwater testing for arsenic undertaken as a government initiative with support from UNICEF has identified many affected regions …show more content…

With a superior platform of ICP-MS used in our laboratory both the drawbacks in arsenic estimation from whole blood was negated. Many studies in India have elaborated on the clinical condition of acute and chronic arsenic toxicity, but very few have actually studied average arsenic levels in the population. Bangladesh and West Bengal have been documented to be worst affected by arsenic toxicity and it has been estimated that 79.9 million are exposed to groundwater contaminated with arsenic from 42 districts in Bangladesh, while from 9 adjacent districts in West Bengal, the number of exposed are roughly 42.7 million [15]. Our study is one of the few to document both frequency as well as average levels of arsenic in whole blood. The frequency of high arsenic levels detected in our study is 1.37% and males were found be affected higher than females at 1.47% and 1.25% respectively. This difference in gender based frequency of high arsenic levels was also found to be statistically significant. Our study also detected maximum affected to be from the State of Kerala and the City of Mumbai in India at 12.6% and 28.5%

An excess level of selenium, which is taken into the body in water and foods, can cause significant side effects like nausea, vomiting, nail changes, irritability in the nose and throat (producing coughing, nosebleeds, dyspnea, bronchial spasms and chemical pneumonia). Exposure to lower levels of Arsenic in the short term can cause nausea and vomiting, swelling and redness of the skin, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels and a sensation of “pins and needles” in hands and feet.

    “How to Poison the Earth” by Linnea Saukko was written as an assignment for a freshman composition class. This essay details a process that humans could take to ensure the definitive destruction of earth. The writer explains that this process might be difficult, due to the fact that the earth has ways to continuously cleanse itself. The first process suggests that large amounts of lethal substances, such as uranium-238 and plutonium, should be produced and then injected into the earth. We would start by building more nuclear plants to help generate more plutonium.

    For this titration, one drop of EBT indicator, NH4Cl buffer, and the water sample were added to each well in a 1x12 well strip. Once each well was filled, the titration proceeded: one drop of the 2 x 10-4 M EDTA was added to the first well, two drops to the second, three drops to the third, etc. Once one of the wells turned a blue color, that particular well represented the point at which there was excess EDTA and all of the Mg2+ combined with the EDTA to remove the ions from solution and form the chelate. Following the test, the equation MEDTAVEDTA= MCa2+VCa2+ was used to calculate the Ca2+ and Mg2+ concentrations.1 Similar to the previous AA test, the water sample was diluted with a 1:1 ratio along with the Atherton and Virginia samples.

    In chemistry, elements have properties that distinguish them from one another. Despite the various chemical properties, one of the most important physical properties is a property known as density. Density was first discovered in 250 BC by the Greek mathematician Archimedes when he compared real and fake gold by placing both in water. The key principle is that density will affect whether objects float or sink. If an object has a higher density than its surroundings, it will sink.

    There are many deadly minerals that litter the Earth’s crust, and without proper research and warning innocent victims might fall to lethal toxins from these minerals. One of these minerals, Arsenopyrite, is a vastly spread and highly dangerous arsenic ore, touching Arsenopyrite without protective equipment can cause arsenic poisoning. By carelessly handling the deadly mineral heavier health concerns will appear and slowly manifest itself to something worse. Yet, not all is bad about the natural creation of this mineral, Arsenopyrite can be used to extract arsenic gas which in very acute doses is beneficial to humans. The unsettling nature of this element still exists with its lethal properties and unless given the proper materials to test
