A study on the concentration and dispersion of Pm10 in UTHM by using simple modelling and meteorological factors

Abstract: Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. Air pollution can also be known as degradation of air quality resulting from unwanted chemicals or other materials occurring in the air. The simple way to know how polluted the air is to calculate the amounts of foreign and/or natural substances occurring in the atmosphere that may result in adverse effects to humans, animals, vegetation and/or materials. The objective of this study is to create a simulation of air quality dispersion in UTHM campus by using computer aided design mechanism such as software and calculating tools. Another objective is to compare the concentration obtained from the end result of calculation with past studies. The air pollutant in the scope of study is Particulate Matter (PM10). The highest reading recorded for E-Sampler was 305μg/m3. It was recorded in Structure Lab sampling point while the highest expected concentration by the Gaussian Dispersion Model was 184μg/m3 for UTHM Stadium. The recommended value for permissible exposure to particulate matter in 24 hours time is 150μg/m3 according to the Recommended Malaysian Air Quality Guidelines.

Comparison of the Air Pollutant Emission Standards of Coal-fired Power Plants between China,the United States and European Union

Abstract: It is an important measure of dealing with environmental pollution problems to scientifically develop pollutant emission standards.The United States,European Union and other developed countries have developed pollutant emission standards suitable for their national conditions and with multiple revisions.In order to learn from the successful experience of pollutant control on the power industry in the developed countries and develop reasonable air pollutant emission standard of thermal power in China,the control process of air pollutants such as SO2,NOx and particulate matters from coal-fired power plants and the current existing emission standards and control technologies in China,the US and EU were compared,the status of pollutant control of coal-fired thermal power in China analyzed,and some recommendations provided for the future development of China′s coal-fired thermal power plants pollution control policy.
