Health Risks Associated with VOC's and are Alternative Compounds Essay

Health Risks Associated with VOC's and are Alternative Compounds Readily Avaialable in Residential Building Use - Essay Example ompounds are gasoline, formaldehyde, benzene, and solvents such as toluene, xylene and tetra-chloroethylene, which is the main solvent used in drycleaning.(www.toxtown.nlm.nih.gov). Volatile Organic Compounds used in building materials are frequent indoor air pollutants. According to Meininghaus et al (2000), certain materials that are present indoors can function as buffers which may reduce the peak concentrations but prolong the presence of the compounds in the air. A two flow system was used in this study to allow direct observation of mass flow across materials. The results in this study showed that diffusion through materials can reduce the room air concentrations, which can affect ventilation requirements. However, VOC levels in indoor air is an important issue of indoor air pollution because most humans spend an average amount of 90% of their time indoors.(Klepeis et al, 2001). Studies show that concentrations of VOCs are typically higher indoors than outdoors and building characteristics can influence the relevant levels.(Wallace, 2001). VOCs are an important category of indoor and outdoor pollutant, although they do not last as long outside because they are easily broken down by microorganisms and sunlight. However, die to their ubiquitous nature, VOCs from indoor sources such as chloroform, p-dichlorobenzene, d-limonene, ÃŽ ±- and ÃŽ ²-pinene are associated with long term health risks.(Pratt et al 2000; Woodruf et al 1998). While the cumulative risks that accrue from long term exposure to multiple VOCs remains indeterminate, the Eleventh Report on Carcinogens which is published by the National Toxicology program identifies damages to the liver, kidneys and the central system in the long term (www.toxtown.nlm.nih.gov). Studies have also shown that several types of cancers as well as cardiovascular and neurological diseases have been reported as adverse health effects of exposure to VOC, either through inhalation or through the presence of VOC’s in

Financial efficiency of Oman Airports Management Company in early Essay

Financial efficiency of Oman Airports Management Company in early recruitment of human resource during the transitional period of Muscat International Airport development project - Essay Example ir ground staff, air traffic controllers, air terminal operations staff, aircraft mechanics, cargo specialists, electronics personnel, passenger specialists, ticketing staff, and radar engineers among others (Young & Wells, 2011: p44). The long-term HR strategy should be geared towards the optimal support of the airport’s corporate strategy and their business situation. Additionally, such mega trends as individualization, diversity, demographic changes, education, and health should be taken into account (Loo & Chow, 2011: p1688). These aspects will then feed into the HR strategy that, in turn, will establish fundamental goals for management of HR and measurement packages that it is associated with. Most of these measures should be implemented immediately and fleshed out as the airport’s development is carried out. The targets for the airport’s HR strategy should be increasing efficiency, covering requirements of personnel, improving the airport’s attractiveness as an employer, and the establishment of excellent leadership (Williams, 2013: p56). Once the airport’s development is finished, the HR strategy should move to recruiting individuals with high personal and professional ambition and a passion to give clients world class customer service (svo.aero, 2014: p1). The recruitment process should seek out individuals with efficiency and high performance that will align with the airport’s strategy of exceeding client expectations. The first priority for the airport in their HR recruitment needs should be accommodating client needs, including visitors, passengers, and employees. The behavior and attitude of recruited staff should support their core values, while also handling the opportunities and challenges of working in an international airport.
