  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • An ambient air quality monitoring network for Buenos Aires city

    This paper proposes an objective methodology for designing a multi-pollutant urban air-quality monitoring network to detect concentrations greater than reference concentration levels (CL). The network design includes both air quality simulation and an objective analysis based on monitoring tasks. The proposed methodology is applied to the city of Buenos Aires. Pollutants of concern are nitrogen ...

  • Comparison of indoor air quality in restaurant kitchens in Tehran with ambient air quality

    Air pollution is a major environmental health problem, affecting developed and developing countries around the world. Although the indoor air database is weak due to the scarcity of monitoring results, these estimates indicate that a serious indoor air problem may exist in developing countries. In developed countries, pollutant concentrations indoors are similar to those outdoors, with the ratio ...

  • 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 ...

  • 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 ...

  • Study of vehicular emissions with reference to Pakistan's National Environmental Quality Standards: case study of District Swat, North of Pakistan

    This study was conducted during 2011–2012 with the objective to assess the ambient air quality in the surroundings of a newly constructed road in relation to Pakistan's Environmental Quality Standard (Pak–NEQS). The area was monitored twice, before and during the construction, to determine levels of sulphur dioxide, nitrous oxide, carbon monoxide, and PM10 (particulate matter). A ...

  • Role of road side plantation in mitigating vehicular emission: a case study of district Swat, Pakistan

    The objective of this study was to know the effectiveness of different tree species used for road side plantation in mitigating air pollution. The road was divided into four zones, i.e., peaches, poplar, eucalyptus, pine rich and treeless zone. The ambient air was monitored periodically over a period of one year with three month intervals. The data was statistically analysed with analysis of ...

  • 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 ...

  • 2013: a ‘perfect storm’ in air quality

    As many countries fail to meet air quality targets and large numbers of premature deaths still result from air pollution, Jim Mills, a particulate monitoring specialist and Managing Director of Air Monitors, explains why 2013 will be a pivotal year. In November 2011 Janez Potočnik, European Commissioner for the Environment, expressed his determination to make 2013 the ‘Year of ...

  • If you can`t stand the CO2, get out of the kitchen - part 1

    There are two potentially dangerous types of gas in a commercial kitchen: 1) the flammable ones used for cooking (e.g. methane/natural gas; propane/liquefied petroleum gas); and 2) the noxious, gaseous products of combustion such as carbon monoxide, carbon dioxide and hydrocarbons. It would be good to know how to avoid them. But a search for advice on kitchen ventilation threatens to drown the ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • 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 ...
