Q1; The chlorinated hydrocarbons are carcinogenic compounds, which have induced the bile duct cancer of workers at printing plants in Japan in 2012. The chlorinated hydrocarbons have been heavily used as cleaning solvent. The atmospheric concentration may be reached at several thousand ppm at work place. By the way, tap water may be contaminated with the chlorinated hydrocarbons, which are unintentionally produced by a sterilization process by chlorine.
Let’s execute shemical risk assessment for ubiquitous chlorinated hydrocarbons of dichloromethane CH2Cl2 or chloroform CHCl3. Let’s make evaluation of Margin of Exposure MOE of dichloromethane CH2Cl2 or chloroform CHCl3.
To evaluate the MOE, we need the estimated amounts of exposure and threshold of safe (termed by “POD:point of departure”). Some organization opened the Initial risk assessment of these chemicals. Please, find the informative documents for executing the risk assessment of dichloromethane CH2Cl2 or chloroform CHCl3.
The procedure is described as follows
(1) Establish the scenario; assuming the situation and condition of intake the chemicals
(2) Estimate the amount of exposure. This is carried out by finding the informative documents, in which the exposure condition is similar to the scenario.
(3) Establish the POD. The confidence of evaluation of POD is enhanced as lowering the uncertainty factors. And, we should also find the effective assessment documents, in which the scenario is as same as possible.
(4) Calculate the MOE, and compare to the uncertainty factors UFs.
The Q2 is the alternative question of Q1. You can choice whether Q1 or Q2.
Q2. Please, try to verify the reports of risk assessment presented by different organization. This comparative reviewing is also executed to your assessment Q1. Comment on the differences in confidence and usefulness by focusing on the scenario, assumption and methodology.
Make comments on the risks by comparison between MOE value and uncertainty factors UFs. Please, download the reports of risk assessment for the interested chemicals from a number of domestic and international organizations. In these reports, find out the amounts of exposure and criteria of safety. We can obtain the MOE value by the ratio of both values. We can download some reports of risk assessments for the same compound. Make comments on the reasons for different results. It should be easy to analyze the reports focusing on scenario, assumption, methodology.
Risk Assessment of Chemical Substances
GCSE War Poem Tunes of GCSE war "Light Battle" and "Fall Battle" are on the whole sonnets about war. Alfred Tennyson's "Light Brigade's Accusation" composed on fourteenth November 1854 clarifies one thing in the Crimean war. England and France are stressed that Russia will move south, so assaulted Russia in Balaclava. During the war in September 1914, Lawrence Bingyan expressed "for fall", yet received a one-sided disposition that shows positive and negative outcomes, specifically. . It is a nation.

With in any event fiction and show, you realize that you will be controlled - in verse, 13 of the 15 sonnets you recall won't show up in your theory. Pick two refrains as tests, analyze them, and request that the understudies connect them to a particular point Clarify how the uncommon attributes of at any rate two works in Wilfred Owen's sonnets influence one another and impact their responses. The center highlights of Wilfred Owen's war verse incorporate misuse of war, fear of war, and the physical impact of war. These highlights can be found in Owen's correspondence with perusers, verse 'Darce and Decolm Est' pulling in perusers' feelings to officers and 'Destiny to youth of fate'. These sonnets collaborate and investigate understanding "Maryal Mountain in this sonnet" clarifies the characteristic picture. Maybe the most well known contemporary use of this sentence is the title of the sonnet "Dulce et Decorum est" by British writer Wilfred Owen during the First World War. Owen's verse depicts the gas assault during the First World War and is one of his numerous enemy of war sonnets that were not declared until the finish of the war. In the last barely any lines of this sonnet, Horatian phrases are communicated as "old falsehoods". Individuals accept and utilize the first of that sonnet to clarify that Owen is attempting to disparage the sonnet by Jessie Pope (who adulated the war and enlisted in a straightforward enthusiastic verse). "Little accomplice" who is excited about charging and shooting. Like "telephone" The principal sonnet mirrors the picture of war that the vast majority know well. This sonnet "Flanders Battlefield" is likely the most renowned and famous war sonnet. It was first distributed in British 'punch' magazine in December 1915. Surprisingly fast, this sonnet represents the penance of all the battle in World War I. "Flanders Battlefield" was made by a specialist and educator of Canada, John McCrea who worked in the South African War and the First World War. He was moved to the clinical group and relegated to a French emergency clinic. He was dynamic in 1918 and kicked the bucket of pneumonia. His sonnet assortment "Flanders Field" and other verse assortments were distributed in 1919. This sonnet is still piece of a commemoration in Canada and different nations.>GET ANSWER
