...Indoor Pollution And Employee Health Tushama Cheris Okraku PRST 5040 – Human Resources Management Dr. Sharon D. Peters Middle Tennessee State University 12/2/12 Abstract Indoor Pollution and Employee Health The paper explores the effects that indoor pollution has on the health of employee from both an employee and employer perspective. It lists some of the issues that are experienced as a result of poor air quality. Environments in which air quality issues are commonly found are also discussed in studies that have been conducted. What causes poor air quality and how they affect employees are communicated to provide a blueprint for organizations to use to prevent such concerns from becoming issues to their employees. Also outlined are ways for organizations to recognize and reduce air quality issues to minimize organizational productivity loss and workers compensation claims that sometimes come as a result of poor air quality. Introduction Employee safety and health concerns have changed drastically over the past couple of decades. They have moved from the bodily injuries of industrial workers to the ergonomic challenges of office workers. These concerns can range from carpal tunnel syndrome to air quality issues. “One of the downsides of opting for environmentally “green” office buildings can produce illnesses such as itchy eyes and trouble breathing, a phenomenon some called “sick building syndrome” (Dessler, 2013; 553). This has caused issues such...

...INDUSTRIAL PRODUCTIONS ON AIR POLLUTION Lu Li, Zhaowei Liu ECON508: Applied econometrics May 10, 2013 Abstract In China, many environmental problems have been ignored when it mainly focused on a higher pace of economic growth for a long time. In this paper, we aim at finding the relationship between air pollutions and its potential contributor—industrial development. And we are also interested in finding out which department in industry contributes most to air pollution. With these questions, it is essential for us to bring our analysis into a practical and comprehensive content. In this paper, we choose air pollution indicators and industry output in provincial level, thus we would like to test it based on different regions. We use the fixed effect model to construct the data and use hypothesis testing to testify our model through three characteristics: normality, heteroskedasticity and autocorrelation. After the regression and test, we come to the conclusion that basically our model is an appropriate one although several data and time series problems limit its further accuracy. And what is more, the result is quite accordance with our assumption that industrial sectors do effect the environment to some extent and among all the sectors we discuss, mining is the most overarching element. In order to obtain a better and more convincing result, we still need more information about air quality in our further study and research. Keywords: air pollution; industrial sector ...

...Impact of Indoor Air Quality Towards Workers’ Health Performance on Safety Engineering Perspective Ahmad Shah Hizam bin Md Yasir (GS40361) andMohd Ruzaimi bin Mohd Ariffin (GS38824) | | | Abstract Deterioration of air quality in working environments has now become an increasing and critical in both developed and developing countries. The potential risks and problems related to indoor air pollution has been recognized, and there is a need to measure and establish air quality standards for those working in any confined environments. For health and safety reasons, the indoor air quality (IAQ) in an enclosed building, where a few people are working in it, was investigated. This study aimed to determine the association between indoor air quality and the workers’ health performance in XYZ Company. A cross-sectional comparative study was conducted among 117 respondents. Assessments on IAQ perception level from staff were conducted through questionnaires, which consist of Indoor Air Quality and Health Performance Survey. The three IAQ variables tested in this study are ventilation, particles contaminant and thermal comfort. DOSH and STRIDE has also measured the IAQ level, which are the concentration of Carbon Dioxide (CO2), Carbon Monoxide (CO), temperature as well as humidity. All data collected were analyzed using descriptive and inferential statistics through SPSS Software. Based on the data analyzed, building occupants’ satisfaction level is identified. Findings show...

...according to EN-15251 and CR-1752, in the built environment based on the percentage of dissatisfied related to the equivalent background noise level. Design/methodology/approach – In the European guideline CR-1752 and the standard EN-15251 three categories of the indoor environment in buildings are prescribed (category A, B and C). In the recommendations, the limit whereby the percentage of dissatisfied should remain under varies in each category for both the thermal indoor environment and the air quality. The categories for noise and illumination criteria are not yet explicitly related to a percentage of dissatisfied. Findings – Using the percentage of dissatisfied as the evaluation criterion, when related to the equivalent background noise, produces a more refined evaluation of comfort than an evaluation based on the percentage of seriously disturbed or the effects of sleep deprivation in relation to external noise. Furthermore, this corresponds to the European standards and recommendations concerning quality classification of the indoor environment, based on the percentage of dissatisfied. Originality/value – Based on recent European undertakings concerning the development of categories for the indoor environment based on the percentage of dissatisfied, it is desirable to utilise these categories to noise aspects too, and to relate it to the equivalent background noise level. Keywords Environmental noise, Noise control, Dissatisfied, Discomfort, EN 15251, CR 1752, Comfort categories,...

...In today’s society healthcare personnel need to be aware of the various chemical, environmental, food borne, water borne and airborne illnesses that abound. Being well versed in this area means understanding the epidemiology, being aware of the signs and symptoms, knowing what treatments or cures and knowing the notification process for outbreaks, should they arise. Severe acute respiratory syndrome also known as SARS is a type of viral Pneumonia that is very serious for those affected. It causes acute respiratory distress for the patient which can cause death. SARS is transmitted by contact. According to the U.S National Library of Medicine the coronavirus can live up to 6 hours on hands, tissues and some other surfaces and can stay active for up to three hours after the droplets have dried (A.D.A.M, 2013). The virus can live in feces for nearly four days and it is unknown exactly how long it can live in freezing temperatures but it is believed to live for months or maybe even years. The Coronavirus family is the same group that births the common cold, just as you can catch the cold over and over again, you can also become re-infected with SARS. Since this is a newer illness only manifesting in 2003 there are still unknowns regarding the illness. One of these things is how long before and after someone is contagious with the infection. It is clear that they are actively contagious while showing symptoms. Usually people who are infected will begin showing symptoms within...

...ENVIRONMENTAL SCIENCES 2 INTEGRATED DESIGN MUHAMAD NAZMI FITRI BIN ABD AZIZ 2014406812 INTEGRATED DESIGN Integrated design is a collaborative method for designing buildings which emphasizes the development of a holistic design. INTEGRATED DESIGN IMPROVES THE ENERGY PERFORMANCE OF BUILDINGS. The conventional definition of integrated design is that project team members from all disciplines work together early and often throughout the project design process. ORIGINS OF MODERN-DAY INTEGRATED DESIGN Integrated design has become a buzzword in the green building world. Everyone claims to do it, although not everyone understands it in the same way, and not everyone is successful at it. DESIGN FEATURES THAT BENEFIT FROM INTEGRATION * DAYLIGHTING * GREEN ROOFS * EXPOSED THERMAL MASS Conventional building design usually involves a series of hand-offs from owner to architect, from builder to occupant. This path does not invite all affected parties into the planning process, and therefore does not take into account their needs, areas of expertise or insights To a growing number of building owners and designers, this linear process needs to change. The process they prefer is called integrated design. It’s built around better communication and more planning. Through the use of integrated design, owners and designers are able to build better, less expensive buildings. The problem is that even though integrated design has been around for nearly a decade...

... | |haque.nymul@gmail.com |jinia_lima@hotmail.com | Abstract Natural ventilation is most desirable for cooling and providing fresh air in residential buildings for better indoor air quality and thermal comfort. The natural ventilation performance is affected by a combination of internal and external factors. External factors include the location, the orientation, the prevailing wind speeds and the building forms of the residential development, which are subject to constraints beyond the control of site planners and architects. Whilst for internal factors like the openings configurations and window types, site planners and architects are always given free hand for a proper design. Dhaka, a city in the Tropics, has become such a city where with rapid urbanization users are moving towards mechanically ventilated buildings putting ever increasing demand on the dwindling energy resources. This paper focuses on the influences of window types on the natural ventilation of residential units in Dhaka in order to improve quality of indoor living environment. Primary objective of the study is an attempt to investigate the performance of different types of windows which is commonly used in residential buildings of Dhaka city. It is expected that the findings will immensely help design professionals practicing all climatic contexts...

...good indoor environment Problems with the quality of the indoor environment have become a new and demanding challenge to occupational health and safety. Modern workplaces resembling office environments that do not have any hazardous exposures originating from work processes can face other problems related to the indoor environment, for example, problems related to substances that are a part of building materials and occur in ventilation. People in Western societies spend more than 90% of their time indoors. Therefore, the quality of indoor environments plays a significant role in their life. Bad indoor air and environments are able to cause work-related symptoms and diseases, while high quality supports well-being and productivity. A good indoor environment not only consists of clean air (including proper humidity, air velocity, and temperature), but also of good acoustics, good lighting, and a good psychosocial environment in the workplace. In Finland, with over 5.5 million inhabitants and 2.5 million employees, the cost of poor indoor environments to society is nearly EUR 1.5 billion a year, mainly as a result of the cost of medical examinations and care, sickness absences, lower efficiency at work, allergies, hospital infections, and cancer. Good indoor environments also seem to affect our creativity, memory, and mood. According to a recent survey of office environments, one out of every three workers complains about constant indoor-air problems, and one out of every five complains...

Executive Summary This paper serves as an addendum to the previously existing Transit Oriented Development in the Triangle Region report compiled by the Triangle J Council of Governments. It analyzes the impacts of light rail transit in regions that are comparable to the Triangle Region (as defined by the region surrounding Duke to NC State to UNC). This study focuses on the effects of Vehicle Miles Traveled (VMT) as a result of light rail implementation. Additionally, we examine how light rail impacts the following sub-categories: environment, economic, and health indices. These indices shape our assessment of whether or not light rail is a worthwhile investment in the Triangle Region. In order to enable politicians to make the best decisions regarding light rail, we provide a comprehensive analysis of peer corridors that are similar to the Triangle Region. Based on population growth projections for the Triangle Region, we find it necessary to offset the corresponding increases in traffic rates and the...

...Quality Improvements in the Air Force James Prentice 15 March 2015 Instructor: Manu Vora The military and the Air Force have a long history of being more progressive in some of their practices than other government organizations, and quality management is no exception to this. After all it is in the best interest of both the military and the taxpayers that support them to perform their duties as efficiently, safely, and as inexpensively as possible. Bearing in mind two facts about quality management in the Air Force. The first being that the Air Force is a government entity and therefore will have directives on everything. In fact there is a directive advising how to go about ensuring quality is embedded in the everyday practices of the Air Force. Secondly, it should always be kept in mind that the Air Force is a big entity and as such is slow to react to advances that other types of organizations are quick to respond to. With this in mind the quality management methodologies employed by the Air Force are quickly catching up to the private sector in regards to complexity and effectiveness. Having entered the military in 2004 I have seen my fair share of quality management techniques employed by the Air Force; in fact by the time I had been in a while and had started to get a feel for how things worked I discovered that many middle management officers and enlisted had seen their fair share of quality management and were in a sense burned out with the half steps...

...Indoor air quality has become more and more important because most people spend more than 80% of their time indoors (APS, 2008). In the last several years, a growing number of scientific evidences have indicated that the air within homes, offices, or other indoor environment can be more seriously polluted than the outdoor air (Sheldon, 1994). Indoors, the concentration of some harmful chemical and biological matters may be hundreds times higher than that outdoors (Sheldon, 1994). Thus, the situation that chemical, biological, and/or physical matters in the indoor air that cause harmful effects to human health is defined as indoor air pollution. One source of indoor air pollutant is chemical matter, which is caused by combustion, architecture material, and some other things. Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species (Wikipedia, Combustion, 2010). In the indoor environment, combustion refers to the use of oil, natural gas, wood, coal, charcoal, and tobacco. During this course, not only the oxygen in the house is consumed, but also much harmful gas like carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2), which is poisonous to human, is produced and flood into the air. Especially in developing countries, where people cook food with burning wood or coal, the indoor air pollution is more serious (WHO, 2010). Another source of chemical...

...Air pollution in Hong Kong is often so bad that it is impossible to see across Victoria Harbor due to all the haze and smog. The government did endeavor to modify the air quality but, sadly, it still deteriorates continually. Even worse, the Air Pollution Index recently hit a record high, which suggests that the air quality in Hong Kong is far lower than the international standard. It all shows that air pollution is just a growing problem and I’m writing to raise several concerns about air pollution and suggest various ways in which Hong Kong citizens can help reduce air pollution. Let us begin with the cause of the problems, which includes three main aspects: vehicle emissions, unplanned use of land, and cross-border pollution. The first aspect concerns the vehicle emissions. With the increasing number of private cars, and the slow introduction of environmentally friendly fuels, the amount of air pollutants released by vehicles keeps increasing, thereby tarnishing the air quality. Secondly, the unplanned use of land can also account for the problems. Due to the limited land supplied, Hong Kong tends to be densely populated while the buildings are usually designed to be as tall as possible. All the buildings therefore form a physical barrier to block the ventilation of air. Consequently, pollutants like suspended particles are trapped in air, causing the air to be polluted. Cross-border pollution is the third aspect. There are currently numerous factories built...

...BIO102 Environment and People Dr. Mike Mooring 09 December 2015 Indoor Air Pollution in Sub-Saharan Africa Introduction Environmental pollution is a major topic and a major global challenge that has become very popular over the last few decades. Air pollution has specifically gained major interests from researchers, governments, and international organizations due to the major impacts associated with it. When a topic such as air pollution is mentioned, most of the people will automatically link it to the idea of things like smog, power plants and emissions from vehicles. However, these are considered examples of outdoor air pollutants. There exists another class of pollutants, which pollute the air inside the houses. These are called indoor air pollutants. Indoor air pollution is when the indoor pollutants or things such as gases and particles contaminate the air indoors. Indoor air pollution refers to the pollution of the air inside the houses or the living spaces. It is the presence of one or more contaminants indoor that carry a certain degree of health risks. The sub-Saharan Africa is among the regions in the world that have been highly affected by indoor air pollution. The aim of this document is to discuss the challenge of indoor air pollution in the region of sub-Saharan Africa. Solid fuel is the major source of this indoor air pollution and particle suspension in the air of these homes. In this region where the population is too poor to be able...
