  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • Weekday/Weekend Differences in Ambient Air Pollutant Concentrations in Atlanta and the Southeastern United States

    Abstract The authors quantified changes between mean weekday and weekend ambient concentrations of ozone (O3) precursors (volatile organic compounds [VOC], carbon monoxide [CO], nitric oxide, and oxides of nitrogen [NOx]) in Atlanta and surrounding areas to observe how weekend precursor emission levels influenced ambient O3 levels. The authors analyzed CO, nitric oxide (NO), and NOx ...

  • Modelling long-term averages of local ambient air pollution in Oslo, Norway: evaluation of nitrogen dioxide, PM10 and PM2.5

    Large seasonal variations in climate as in Norway give challenges for air pollution modelling, especially of Particulate Matter (PM) that seldom has been evaluated. The EPISODE model calculated ambient concentrations of nitrogen dioxide (NO2), PM with diameter ...

  • 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 ...

  • IFDM modelling for optimal siting of air quality monitoring stations around five oil refineries

    An IFDM modelling study has been conducted to determine the optimal siting of air quality monitoring stations around five oil refineries. The purpose of this immission monitoring network is specified in environmental legislation. The most appropriate output parameter of the IFDM model for this study is the 98th percentile of the moving 24 h averages, P98,m24h. Modelling for the optimal siting of ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Ambient air quality levels in Tehran, Iran, from 1988 to 1993

    The objectives of this study were to describe trends in ambient air quality in Tehran between 1988 and 1993, to determine if these levels exceeded the World Health Organization (WHO) guidelines, and to discuss possible health effects related to exposure for these particular pollutants. Data were acquired from Iran's Environmental Protection Agency (IEPA) and the Ministry of Health (MH). These ...

  • Ambient air quality of Kathmandu valley as reflected by atmospheric particulate matter concentrations (PM10)

    This paper presents the analysis and interpretation of ambient particulate matter concentrations measured as PM10 at a network of six air monitoring stations in Kathmandu valley during the years, 2003 through 2005. The purpose was to understand the pollution trends associated with different areas considering levels particulate matter concentrations representing the ambient air quality of ...

  • Air pollution – the invisible roadside killer

    The VW emissions scandal has helped to raise awareness of the deadly threat posed by air pollution in many of our towns and cities. In the following article, Jim Mills, Managing Director of Air Monitors, an instrumentation company, explains why diesel emissions will have to be lowered and how the latest monitoring technology will be an essential part of the solution. ...

  • Air pollution in Europe 1990-2004

    Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate ...

  • 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 ...
