  • Industrial Hygiene: Quality Assurance In Air Sampling and Analysis

    Industrial hygiene is the recognition, evaluation, and control of chemical, physical, biological, and ergonomic stresses in the workplace. Of the stresses listed, chemical stresses in the form of air contaminants are the most common. Air contaminants, their PELs and TLVs, and how to sample for them, is Industrial Hygiene 101 for most industrial hygienists. However, as simple as sampling and ...


  • Ambient Air Quality Analysis of Toxic Gases and Priority

    The EPA regional offices who continuously monitor ambient air quality have determined that combustion by-products and automobile exhaust make up the largest source of air pollution throughout the U.S., with more severe conditions existing overseas. Despite concerns about the conditions outdoors, air quality in the workplace and home environment receive even more attention. The EPA’s list of ...

  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

  • Better air quality in Oslo

    Norwegian Institute for Air Research (NILU) has performed trend analysis of exposure to air pollution for Oslo, the capital city of Norway, in the period 1995 – 2001. In this period, the number of persons exposed to concentrations of PM10 above the Norwegian guideline for good air quality, were reduced with approx. 100 000 ...

  • Improving air quality in the office

    Most people spend the main part of their day indoors – in the home, school or office environment. Focusing specifically on improving air quality in the office and workplace setting, we are looking at the key potential sources of pollution which impact upon air quality and employees’ health. Examples include, outdoor air (particularly relevant if the workplace is next to a busy road), ...

  • Air quality in America

    Although most Americans tell pollsters they believe air pollution in the United States is getting worse, the reality is quite different. In 'Air Quality in America: A Dose of Reality on Air Pollution Levels, Trends, and Health Risks' (AEI Press, January 2008) environmental scientist Joel Schwartz and political scientist Steve Hayward demonstrate why air pollution has been dropping steadily for ...

  • Analysis of the impacts of an environmental traffic management system on vehicle emissions and air quality

    Environmental traffic management systems (ETMS) are implemented to improve air quality in urban streets. They allow for a situation-related control of light signal systems to optimise road capacities and enhance traffic flow in street sections. Therefore, they are equipped with mitigation strategies and continuously provided with traffic and air quality data. In this context, it is ...

  • Investigating weekend air quality observations with the aid of Fourier analysis in Athens, Greece

    Weekend air quality is analysed with the aid of Fourier analysis, in order to reveal time-series structures for Athens, Greece. For this reason, an appropriate analysis of a 10 year record from 1990–1999 of air quality data from the monitoring network in Athens is carried out for two specific monitoring sites. The aim of the paper is to investigate the temporal pattern of observations in order to ...

  • Uncertainty analysis of modelling studies included in air quality assessments

    This paper deals with the development of a quality analysis/quality control (QA/QC) methodology for modelling studies associated with air quality assessments. Among other benefits, this will allow data quality objectives for model input data to be derived and the importance of policy oriented model applications to be assessed. The procedure for evaluating model uncertainty has profited from a ...

  • A quantitative approach to the traffic air quality problem: the traffic air quality index

    The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...

  • Air quality in Europe — 2011 report

    The present report provides an overview and analysis of air quality in Europe. The analysis covers up to 38 European countries (EEA-38) (1) and spans the two decades of data that countries have made officially available up to 2009. The evaluation of the status and trends of air quality is based on ambient air measurements and data on anthropogenic emissions and trends. Emissions of the main air ...

  • Air quality in Europe — 2012 report

    'Air pollution is bad for our health. It reduces human life expectancy by more than eight months on average and by more than two years in the most polluted cities and regions. Member States must comply with EU air quality standards quickly and reduce air pollutant emissions,' Janez Potočnik, EU Commissioner for the Environment (EU, 2010a). Emissions of air pollutants derive from almost all ...

  • A modelling system for air quality management

    To develop effective air quality management strategies at regional and urban levels requires the preparation of several actions belonging to different scientific areas and analysis of their complex interactions. A well-structured management system must be based on efficient tools that integrate diverse sets of information - emissions, traffic, meteorological variables and air quality data. ...

  • Air quality in Europe - 2014 report

    Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...

  • Air quality in Europe — 2015 report

    Air pollution is both an environmental and a social problem, as it leads to a multitude of adverse effects on human health, ecosystems, the built environment and the climate. Air pollution poses the single largest environmental health risk in Europe today. Air pollutants are emitted from anthropogenic and natural sources; they may be transported or formed over long distances; and they may affect ...

  • Air quality in Europe — 2013 report

    Air quality continues to be a very important issue for public health, the economy and the environment. Europe has significantly cut emissions of several air pollutants in recent decades, greatly reducing emissions and exposure to substances such as sulphur dioxide (SO2), carbon monoxide (CO), benzene (C6H6) and lead (Pb). Despite improvements over several decades, air pollution continues to ...

  • Air quality modelling: an investigation of the merits of CMAQ in the analysis of trans-boundary air pollution from continents to small islands

    The purpose of this study is to conduct an air quality modelling assessment of trans-boundary air pollutants from the Asian continent by applying an advanced modelling system – the Community Multi-scale Air Quality (CMAQ) – developed by the US Environmental Protection Agency (USEPA). The focus of the study is trans-boundary ozone, Particulate Matter (PM), and acid deposition, using selected ...
