Comparative Investigations On Microextraction And Conventional Air Sampling Techniques: Challenges And Future Directions, Firoz Ahmed, Mehedi Hasan Roni, Ashiqur Rahman, Sayed M A Salam

Al-Bahir Journal for Engineering and Pure Sciences

Microextraction technique (e.g., solid phase microextraction, thin film microextraction, in-tube extraction) brings a revolutionary change in air sampling techniques over the recent few years. This advanced technique exhibits a high pollutant extraction rate, a low retention time, and a lower error margin compared to conventional air sampling techniques. The accuracy range of microextraction technique (MET) was recorded ~90-95% to isolate the volatile organic components, oxygenated and halogenated carbon particles from the air. However, the efficiency of MET increases additional >3-5% when employed by coupled with gas chromatography or gas chromatography-mass spectrometry. The conventional sampling techniques (e.g., bag sampling, grab sampling) …

Sources And Techniques Of Domestic Heating Within Tritia Region, Malgorzata Wysocka, Krystian Skubacz, Krzysztof Samolej

Journal of Sustainable Mining

The paper presents the balance of energy consumption for domestic heating in Opole and Silesian Voivodship (Poland), divided into various media. The report was based on an analysis of approximately 250 documents containing low-carbon economy plans for individual municipalities (gminas). The authors compared the current situation in these voivodships and their districts with the structure of the heating system in Poland as a whole, based on data from the Central Statistical Office of Poland. The data demonstrate that the use of coal-based energy media has not changed significantly over the years and around 55-60% of households with individual heating systems …

Global Air Quality Trekkers: Nandi Clean Kitchen Study, Samantha Dykhuis, Stephanie Schiavo, Avalin Senefeld

Purdue Journal of Service-Learning and International Engagement

Indoor air pollution is a widespread environmental health challenge sub-Saharan Africa and is the leading cause of premature death in many sub-Saharan African countries. This pollution is primarily caused by the burning of biomass fuels inside an enclosed kitchen in order to provide heat for cooking. Global Air Quality Trekkers is an undergraduate engineering team within the EPICS department at Purdue that began in fall 2016. Our objective is to create a kitchen design that utilizes natural ventilation to mitigate the amount of air pollutants present in these kitchens, specifically in the Nandi community of Western Kenya. This year, our …

Flooding, Landslides, Wildfires, Air Pollution, And Income: Risk In California, Brittany Bondi, Alyssa J. Kaewwilai

Gettysburg Social Sciences Review

California is infamously known for its likelihood of environmental hazards such as flooding, landslides, air pollution, and forest fires which can be attributed to the natural climate of the area as well as anthropologically influenced climate change. Air pollution also poses potential threats and dangers to the civilians of California as increasing populations and uses of fossil fuels continue to contribute to the growing issue of climate change. The goal of this study was to examine and analyze the geospatial trends environmental hazards in California such as landslides, air pollution, flooding, and forest fires. A weighted test, zone and slope …

The Effect Of Particles Pm10 And Pm2.5 In Dust Emission Of Urban Infrastructure From Thermal Power Plant Technology Kosovo, Afrim Syla

International Journal of Business and Technology

Airborne particulate matter with aerodynamic diameters less than 10 microns (referred to as PM10) is one of the six criteria pollutants used by the U.S. Environmental Protection Agency as indicator of air quality. During the last decade, the health effects of urban aerosols have become a major concern for the society.

The main environmental problems in Kosovo include all issues related to water supply and sanitation system, air quality, solid waste management and urban infrastructure. The major problem remains high pollutions, energy losses and low collection efficiency. The awareness of environmental issues among the general public is poor. Air quality …

Improvement Of Air Pollution Prediction In A Smart City And Its Correlation With Weather Conditions Using Metrological Big Data, Talat Zaree, Ali Reza Honarvar

Turkish Journal of Electrical Engineering and Computer Sciences

Smart cities are an important concept for urban development. This concept addresses many current critical urban problems including traffic and environmental pollution. As utilization of the Internet of things and technology in smart cities increases, large volumes of big data are generated and collected by sensors embedded at different places in the city, which present a real-time display of what is happening throughout the city at all times. Such data should be processed and analyzed as a response to ensure effectiveness and improvement in quality of provided services; correct use and analysis of such data is valuable. Big data mining …

Coke Oven Emissions: A Case Study Of Technology-Based Regulation, John D. Graham, David R. Holtgrave

RISK: Health, Safety & Environment (1990-2002)

After examining and analyzing the experience with coke ovens, the authors conclude that attempts to force technology beyond its demonstrated competence can be both expensive and ineffective in controlling hazards. They also suggest implications for pending proposals to further control air pollution.
