  • States propose attainment designations for the new 1-hour So2 NAAQS

    The U.S. EPA revised the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2) on June 2, 2010 by implementing a new 1-hour standard of 75 parts per billion (ppb) (calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations). Based on an evaluation of the risks posed by acute exposure to SO2, EPA ...

  • The CO2 and SO2 capture capability of two Greek limestones during repeated thermal cycles

    In the present study, two Greek limestones from the Megalopolis and Florina areas were used to capture CO2 and SO2. The regeneration ability and decay of the limestone samples were investigated through sorption-calcination cycles in a thermogravimetric analyser operated at ambient pressure. The effects of the sorption time (3, 8 and 30 min), reaction temperature (750°C and 850°C) and particle ...

  • Statistical analysis of urban air-pollution data in the Athens basin area, Greece

    Air pollutant concentrations recorded in the Athens basin area by a network of stations are analysed and examined to estimate the typical behaviour of the air pollutants, especially with regard to daily, weekly and annual periodicities and meteorological dependencies. Also, an attempt is made to predict daily and monthly concentrations by utilising a statistically based model, that is, a multiple ...

  • EPA establishes new 1-hour standard for sulfur dioxide

    On June 2, 2010, the U.S. EPA established a new 1-hour primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). The new 1-hour standard was set at the level of 75 parts per billion (ppb) calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations. With the establishment of the new 1-hour SO2 standard, ...

  • Using exergy to assess air pollution levels from a smokestack ? Part 1: methodology

    Exergy is proposed as a standard to assess the potential impacts of smokestack pollutants, such as those from coal boilers and power plants. A method is developed which analyses the exergy distribution of emissions such as SO2, NO and CO2, and heat. In a companion paper, spatial variations are illustrated for temperature, concentration, thermal exergy, chemical exergy and exergy of the ...

  • Experiences in the modelling of traffic policy measures for ambient air quality management in Lithuania

    This paper presents the application of the Integrated Transport Effect Modelling System (ITEMS) in the city of Kaunas, Lithuania, taking into consideration some factors such as existing vehicle fleet, traffic flows, and ambient air quality monitoring data. The objective of this study is to estimate the exhausts of CO, NOx, and SO2 released by motor vehicles in relation to predictive traffic ...

  • Exergy analysis of the process of wet-process phosphoric acid production with full utilisation of sulphur contained in the waste phosphogypsum

    The wet-process phosphoric acid is produced by decomposition of phosphate raw materials with sulphuric acid. This gives a large amount of waste product-phosphogypsum. The thermochemical decomposition of phosphogypsum gives a gas rich in SO2. This gas is processed to obtain sulphuric acid, which is fed back into phosphoric acid production. The aim of this paper is to perform exergy analysis of the ...

  • Replacement of hazardous chromium impregnating agent from silver/copper/chromium-impregnated active carbon

    Activated carbon (AC) is widely used as an effective adsorbent in many applications, including industrial-scale air purification systems and air filter systems in gas masks. In general, ACs without chemical impregnation are good adsorbents of organic vapors but poor adsorbents of lowmolecular-weight or polar gases such as chlorine, sulfur dioxide (SO2), formaldehyde, and ammonia (NH3). ...

  • New Nitrogen Dioxide Ambient Air Quality Standard Could Pose Challenges

    In the more than 200 air quality modeling analyses that ALL4 meteorologists have conducted, demonstrating compliance with the annual nitrogen dioxide (NO2) National Ambient Air Quality Standard (NAAQS) of 53 parts per billion (ppbv) has rarely been an issue.  The relative ease for demonstrating compliance with the annual NO2 NAAQS is due to two (2) factors.  First, the ...

  • Understanding ambient air quality instrument operating ranges

    In order to maximize the performance of an air quality monitoring station, careful selection of instrumentations is essential. One of the key issues is to have a good understanding of what pollutants need to be measured and at what concentrations. There are several different types of air quality monitoring, these include: Trace/Background Monitoring This is performed in areas where ...

  • Final report Experimental Study Investigating Risks of selected Amines (ExSIRA)

    Summary The effect of selected amines on the corrosion of carbon steel and copper was investigated in the laboratory and in the field. The steel and copper samples were exposed to loads of the amines in the laboratory, representing estimated 10 years worst case exposure due to emission from a CO2 capturing plant at the Technology Centre Mongstad (TCM). No effect on the corrosion rate for ...

  • Time series analysis for the sulphur dioxide and particulate matter concentrations in the Aegean Region of Turkey

    Air pollution has temporal and spatial variability. Time series analysis is commonly used to evolution of air pollutants in time. The sulphur dioxide (SO2) and particulate matter (PM10) concentrations in the cities of the Aegean Region for the period of 1990–2009 have been modelled by using autoregressive (AR) and autoregressive moving ...
