Air Pollution - Research Paper Example The issue of Air Pollution has is not new and was part of the environmental crisis that started with the industrial revolution however the situation today is far more complicated and critical as compared to 50 years back with environmental pollutants causing problems like ozone depletion, global warming and acid rain (Wark, Warner, Davis). Air pollution is almost impossible to contain because of its ability to spread rapidly over a large area. Air pollutants are of various kinds with different physical characteristics and chemical properties and have varying effects on the environment and human health. The various environmental issues are inter-related for example the issue of global warming is aggravated by the increased ozone depletion due to various environmental pollutants. The various environment protection bodies including the United Nations Environmental Program is taking various steps to prevent air pollution and reduce the use of several different chemicals and process which result in air pollution. The UNEP issues regular recommendations to the governments for passing legislation for eradicating the use of harmful chemicals and industrial processes which contribute to environmental pollution. The various other initiatives taken by international environmental protection bodies and agencies include the Kyoto Protocol, the Montreal Protocol and carbon footprint reduction programs but these efforts have not achieved the desired objectives till date. The situation of air pollution is worsening every other day primarily because of the lack of awareness among common people about the adverse effects of various daily life products they use and their activities which pollute the environment. People are concerned about an issue when they have to face the consequences but in case of air pollution, there are cases in which the pollution is caused by the activities of one region while people of other regions have to face the consequences, for instance the Scandinav ian regions are affected when the European countries of the south pollute air, similar is the case with the harmful chemicals issued by the industries in China which pollute the Japanese regions (White, Beal). The sand storms in North Africa are responsible for red rains in Europe across the Mediterranean. So the issue of air pollution is a global issue and must be dealt by all the nations of the world collectively but the overall scenario of the world regarding the environmental protection is not very encouraging because the countries only think about their own interests and do not act to solve the problems globally because most of the countries are not willing to sacrifice their economical benefits for the environmental protection cause. Pollutants in the air a serious environmental issue because the society today is highly industrialized and the various harmful chemicals like radon, lead, asbestos, ozone, carbon monoxide etc. which have been classified as environmental pollutants are issuing from various industries. The various air pollutants are discussed in the following paragraphs. Carbon Monoxide is a colorless, odorless gas which is fatal for humans if

Primarily, low t-cell count is the sole determinant of the progression and infection rate of the HIV and AIDS patients, and the only option the patients have is taking the standard-multi drug regime which have adverse side effects. However, the new developed powerful drug will helps raise t-cell counts in AIDS patients and retard disease progression for those who have been in decline for years or months therefore offering the same level of efficiency derived by taking â€Å"cocktail† of powerful medications. The new drug is believed to be as efficient as the standard multi-drug regimen. With the average efficiency of the new drug  µ1 and  µ2 being the average efficiency of the latter, the hypothesis will be represented as follows: Considering that the new drug’s efficiency will be compared to the multi-drug regimen, an applicable definition of efficiency will be considered. In this respect, efficiency will be defined as the drug’s ability to produce certain effects on the patient without respect to the quantity administered (Pokrovskii & Kompaniets, 2008). The 60 AIDS infected persons will be selected through random assignment which will be targeted from the Annual AIDS campaign day where all countrywide affected and infected persons gather. At the campaign, the new drug benefits and possible side effects will be clearly elaborated and patients interested in both control and experimental group asked to volunteer. A group of 100 patients have to be tested for their t-cells blood counts. Among them, 20 of them must have been in decline for months or years. From the names, 30 patients will randomly be picked as the Control Group including 10 patients among the tested 20 who have been in decline for
