  • Analysis of local concentration gradients in complex built environments: implications for Air Quality Management Areas

    This paper reviews the existing guidance on placement of permanent air quality monitoring stations within urban areas and suggests the principles for a new, performance-based guidance. An integrated air quality model has been developed and validated for the designated Air Quality Management Area (AQMA) located in Glasgow City Centre to analyse the importance of local concentration gradients on ...

  • ‘New for old’ dust analyser deal brings 96.66% data capture rates to NE Lincs

    With the UK’s largest port and the industrial town of Grimsby in its jurisdiction, air quality monitoring is a primary concern for North East Lincolnshire Borough Council. When DEFRA reported that the TEOM dust analysers the council relied on weren’t up to standard, rapid action was required and Enviro Technology (ET) stepped in with its BAM 1020s. North East Lincolnshire is the ...

  • Lisbon air quality forecast using statistical methods

    Ozone and particulate matter levels in Southern European countries are particularly high, exceeding the established limit values, and the information and alert thresholds (in the case of ozone). Therefore, it is relevant to develop a good prediction methodology for the concentrations of these pollutants. Statistical models based on Multiple Regression (MR) analysis and classification and ...

  • Criteria for the assessment of air quality levels in homogeneous areas

    A methodology is proposed for the appraisal of the data to confront with air quality limits. The methodology assesses air quality levels on the basis of mean values calculated as an average of all data collected in homogeneous areas, from monitoring stations located in sites not conditioned from local sources emissions. The resulting value represents the air quality of the area better than a ...

  • 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 ...

  • The US Clean Air Act: Improving air quality and tracking greenhouse gas emissions?

    The US Clean Air Act is a federal law designed to reduce air pollution in order to improve the nation’s overall air quality. The intent of the federal law is to identify and reduce harmful substances that weaken the stratospheric ozone layer and continue to contribute to global climate change.Many of these pollutants, refrigerant gases, or Greenhouse Gases (GHGs) can be found within companies, ...

  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost 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 ...

  • 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 ...
