Question 1, Part A Question 1, Part B The RMOS value is not acceptable in this case since it is astronomically high, which suggests that it is very dangerous. According to Soylu and Kunduz (2013), although toluene is defined as a class 3 substance (not classifiable as carcinogenic to humans), there are adverse chemical effects to humans. This includes, but is not limited to muscular incoordination, neuronal degeneration, and personality disorders (Soylu & Kunduz, 2013). Question 2 The precautionary principle is an extremely important rule for people to consider at all times. The short-term benefits of new drugs or processes can be very appealing to the end user, however if the long-term effects of the drugs are unknown, the user could potentially be harming themselves more than benefiting themselves. There have been cases in the past that illustrate the potentially devastating consequences of not following the precautionary principle. Thalidomide is a sedative that once caused a worldwide epidemic of birth defects. The drug was as a cure for nausea and morning sickness. As a result, it was prescribed to many …show more content…
For instance, according to Rowland (1990), chlorofluorocarbons (CFCs) were used throughout most of the 20th century for various applications such as in the manufacture of aerosol sprays, as blowing agents for foams, as solvents, and as refrigerants. The long-term effects of the chemical were not studied, and it was later discovered that it was depleting areas of the ozone layer (Rowland, 1990). As a result, UV-B radiation from the sun has passed much more easily than it otherwise would have in those areas, causing mortality rates of local organisms to increase (Aggarwal, et al., 2013). Thus those areas of the biosphere have had their ecosystems disrupted, in addition to causing diseases in humans such as skin
The moral philosophy best describes my personal decision making is virtue ethics (Ferrell, Fraedrich, & Ferrell, 2013). It best description of me as virtual ethics having exceptional moral character (Ferrell, Fraedrich, & Ferrell, 2013). My character displays honesty, integrity, and helpfulness (Ferrell, Fraedrich, & Ferrell, 2013). For example, a friend attempted to commit suicide as a result of a wife asking for a divorce through email (Ferrell, Fraedrich, & Ferrell, 2013). However, while working I received a phone call from him stating his desire not to live anymore (Ferrell, Fraedrich, & Ferrell, 2013). Meanwhile, I called his son to ensure that he wasn’t alone however, his son drove to the house and found his father sitting and with a
The DOT (also know as USDOT) Number is an ID for federal safety regulations. The MC Number is your "Interstate Operating Authority." This is the $300 fee I believe you were referring to. The cost is dependent on Authority. 'Permanent Authority has a filing fee of $300."
The goal of Clark Consulting remains to help develop a more secure network for Harry and Mae’s Inc. in that vein, Clark Consulting has determined some final additions and changes to the Harry and Mae’s Inc. network. The additions include a Bastion server, Network Intrusion Detection System (NIDS), Host Intrusion Detection System (HIDS) and a Security Information and Event Management (SIEM) server. The changes will primarily revolve around passwords.
15.2) The accumulation of chlorofluorocarbons is responsible for depleting the atmospheric zone. The atmospheric zone has changed in concentration due to human activity. The CFCs release chlorine atoms which react with ozone reducing it to molecular O₂. Following chemical reactions release the chlorine which reacts with other ozone molecules in a catalytic chain reaction. The ozone layer is getting thinner and thinner as stable air at places such as Antarctica allows reaction to continue. The accumulation of CFCs has led to increased UV radiation in sunlight reaching the earth thereby decreasing ozone levels. The global temperature has increased.

1.“If, for example, students were not ultimately rewarded for spending their early adulthoods pursuing undergraduate, graduate, and professional degrees, or if the hardest-working and most productive workers were paid the same as the median worker, then citizens would have little incentive to develop expertise, to exert effort, or to excel in their work.”
Another poisonous chemical was being used on humans. Mistakes made in the past caused a great deal of health problems to children around the world when it was discovered that using a tranquilizer called thalidomide caused severe birth defects. Babies were born with hands and feet like flippers, attached to the body with little or no arm or leg. Every compound drug containing the sedative was taken off the market. The 1960s began under the shadow of the Cold War and ended under the shado wo fthe Vietnam War.
Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. One American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are now being used in the place of CFCs that will not damage statospheric ozone, and there is international recognition of the importance of developing these chemicals. The Montreal Protocol is an international treaty which limits the production of ozone depleting substances. Still, human health is at risk from the deletion of ozone, and the risk factor will continue to rise unless people and industries become more aware of the implications connected with everyday use of chemicals which destroy stratospheric ozone.
Pollution is a massive problem, due to burning excessive amounts of fossil fuels and produces global warming. The rising in temperature of earth has resulted huge melting of polar ice caps, flooding of low-lying areas, and also rise in sea levels. If these conditions conquer the surface of earth it will face radical changes. Hence, the ozone holes are also being created trough this process, that creates a harmful UV rays that enters the earth surface. Apparently it affect human life trough causing diseases like cancer. Melanin that present in the skin reacts trough these high wave radiations. Skin cancer is one of the major forms of disease that known to be caused due to these reactions of the pigment present in the skin and infra-red rays. Besides that, when burnt sulphur, dioxide gas will also be produced. This factor forms acid rain. Acid rain could leads to destructions of most of monuments that were made up of brickwork or marbles. Even a lot of crops are affected due to the acidification of loams.
In addition to their many adverse effects on the human body, flame retardants also represent a hazard to the environment. They have similar effects on other animals as they do on humans. Even after certain types of flame retardants’ production was stopped after the discovery of their dangerous effects, they are still being detected in the environment, and are therefore still disturbing the ecosystem. (Guigueno,
During the first half of the 20th century, two world wars wreaked havoc on the world politically, economically, geographically and socially. As tremendous changes were taking place reshaping the state of the world, at the home front, new discoveries began to restructure the world of medicine. The general public and medical practitioners observed a shift from infectious diseases to chronic diseases. This shift required a reevaluation of what it meant to have a sickness or disease. Promising medical discoveries were proven to be able to prolong life and provide comfort to those living with chronic illnesses and diseases. Although, these remarkable discoveries gave the chronically ill hope for longevity, but the economic downfall of the beginning of the century, left many people unable to have access to the new treatments. ¬¬

In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found that human-made chlorofluorocarbons used for making foam, cleaning fluids, refrigerants, and repellents transform into ozone-depleting agents.3 Chlorofluorocarbons stay in the atmosphere for several decades due to their long tropospheric lifetimes. These compounds are carried into the stratosphere where they undergo hundreds of catalytic cycles with ozone.4 They are broken down into chlorine atoms by ultraviolet radiation.5 Chlorine acts as the catalyst for breaking down atomic oxygen and molecular ozone into two molecules of molecular oxygen.

Some people are at especially high risk for health problems associated with ozone. These include children, who normally spend a lot of
