  • Assessment of material deterioration in Bulgaria owing to air pollution

    Atmospheric pollution is an important factor in material deterioration, including degradation of systems used for material protection. Owing to pollution, the lifetime of technological products is shortened. Buildings and other structures, as well as objects of cultural heritage exposed to the atmosphere, deteriorate more rapidly. The resulting physicochemical and economic damage can be ...

  • Association of Self-Reported Leisure-Time Physical Inactivity with Particulate Matter 2.5 Air Pollution

    This study examines the association between annual levels of particulate matter (PM2.5) and self-reported leisure-time physical inactivity (LTPI) in the Behavioral Risk Factor Surveillance System (BRFSS) among 63,290 survey respondents who participated in the 2001 BRFSS from 142 counties in the U.S. The average prevalence of self-reported LTPI was about 24.9% (SE = 0.3%). LTPI prevalence was ...

  • First evaluation of a novel screening tool for outlier detection in large scale ambient air quality datasets

    Systematic collection of long term meso- to large-scale datasets of ambient air quality provides an indispensible means for air pollution monitoring. However, the quality of these monitoring data depends on the chosen method of measurements and the QA/QC procedures applied. We present the first version of a prototyped screening tool for the automatic detection of outliers in large data volume ...

  • Finding Air Pollution Solutions by Tracking Particulates and Gases

    An estimated 95% of people live in areas where outdoor fine particulate concentrations exceed the air quality guideline of 10 µg/m3 set by the World Health Organization. Almost 60% of people live in areas where fine particulate matter exceeds even the least stringent WHO interim air quality target of 35 µg/m3. These figures are presented in the State of Global Air 2018 project, and ...

  • Introducing a New ASTM Method for the Determination of Total Nitrogen, and TKN by Calculation, in Water Samples

    The USEPA Clean Water Act (CWA) requires national approval for all methods used for CWA compliance. There are approved methods for the determination of inorganic nitrogen (NO3-N, NO2-N, and NH3-N), and for organic nitrogen (TKN – NH3-N)2. There are no EPA approved methods for the determination of total nitrogen although it is a required parameter in many USEPA permits, including monitoring ...

  • Monitoring - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • Case-Study: Power Plant Air Quality Monitoring

    Coal, fly ash, and secondary particles emitted from thermal power plants contribute to more than 30% of PM2.5 generation in India. To meet the emission standards, the GMR Warora thermal plant needed to monitor and reduce the pollutants generated by stacking and moving of raw materials. Oizom Polludrone was installed to identify and monitor the ambient pollution level. The solution assisted in the ...
