  • What is sustainable air quality?

    For 40 years or more, air quality policy has been based on the paradigm of the air quality standard as a uniform criterion of acceptable environmental degradation, built on the foundations of the precautionary principle. However, developments in health science have undermined some of the underlying assumptions of this paradigm whilst technological emission controls have been offset by growing ...

  • 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 ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • Intellisenc Building Air Quality Controllers control CO2, CO, VOC, O3, Humidity and temerpature.

    The quality of the air we breathe indoor (Indoor Air Quality, IAQ) is typically defined by the air chemical or gas composition and particulates. The sensors available today for sensing the gas composition of IAQ have many features and options. There is a wide application base for IAQ sensing with the most common being the regulation of HVAC ventilation systems for lower energy cost. Using an IAQ ...


  • Update and revision of Turkish air quality regulation

    The Air Quality Assurance Regulation (AQAR) was issued on October 1986. This regulation was basically a direct translation of the German TA-Luft of 1984. The main purpose of AQAR was to control the effect of industry, domestic heating and Traffic on ambient air quality which previously had not adequately been represented. Two new regulations, "Industry Related Air Pollution Control Regulation" ...

  • Air quality monitoring and assessment programme for Botswana

    An Air Pollution Monitoring and Surveillance Program (BAQMAP) is being developed, installed and tested for Botswana. The project is funded partly by NORAD and partly by the Botswana Government.  The project is undertaken in a co-operation between Norwegian Institute for Air Research (NILU) in Norway and Department of Mines (DoM) in Botswana. NILU shall provide professional assistance in the ...

  • AirQuis: A modern air quality management system

    AirQUIS represents the main tool for establishing and integrating the different components of the AQMS. AirQUIS is the air pollution module of an Environmental Surveillance and Information System (ENSIS), developed by NILU in co-operation with other institutions. The system has been established and operated in several cities and urban areas world-wide. It received the European IT prize in 1998, ...

  • Controlling Air Pollutants case study

    While it's not always easy to determine what's required for compliance, new technologies can help achieve air-pollution control Selecting air-pollution control equipment can be tricky. It's not only difficult to determine which pollutants must be controlled, but also which type of equipment will best control them to required levels for any given process or facility because there is no ...

  • Economic Evaluation of Air Quality Targets for Tropospheric Ozone

    The study identifies and estimates the (least) costs and benefits of meeting ambient air quality standards (different sets of limit/target values) for tropospheric ozone in the EU, taking into account deposition constraints for acidification. This report is divided into three parts: Part A describes the methodology of the analysis and reviews the databases used for the scenario calculations. ...

  • Ambient Air Quality in India - An Alarming Report

    Are we mortgage India against air pollution? The answer may be “Yes”. The reason is India has witnessed a phenomenal increase in the number of industries and vehicles in the last decade, along with the mushrooming of cities. As a consequence, there has been a dramatic deterioration in the quality of urban air in most regions of the country particularly in big cities like Delhi, Mumbai, Kolkatta ...


  • Passive samplers for air quality monitoring in a Brazilian university

    The aim of this paper was to evaluate the applicability of passive samplers for the monitoring and diagnosis of air pollution at Passo Fundo University, focusing on atmospheric pollutants NO 2 and O 3 . The samplers were built in accordance with already verified methodologies and were placed in several locations in the university campus, namely: energy generator, pool heating boiler, ...

  • Confronting allegations of air quality non-compliance

    A facility with an air quality permit must comply with all the conditions of that permit and demonstrate its compliance on an on-going basis. Unfortunately, no matter how diligently the facility and corporate staff strives to assure continuous compliance, unexpected compliance challenges can occur. For example, new equipment fails the emissions guarantees provided by equipment vendors; new staff ...
