  • Green infrastructure in street canyons could reduce air pollution

    Planting vegetation in city streets could significantly reduce air pollution in urban street canyons, according to new research. Traffic pollutants are deposited on vegetation at a higher rate than on hard, built surfaces and could reduce the concentration of nitrogen dioxide (NO2) and PM10 in the air by as much as 40% and 60%, respectively, under certain conditions. Outdoor air pollution ...

  • Chicago`s Oak Street Beach contaminated with asbestos

    The Illinois shoreline and Illinois Beach State Park have a long history of asbestos contamination, so as the 2008 beach season opens on Lake Michigan, a conservation group is advising beachgoers how to minimize inhalation of cancer-causing asbestos fibers. For at least 20 years, asbestos fibers were released daily and carried southward by Lake Michigan's currents from the Johns-Manville ...

  • Hong Kong street-level air quality forecasting and exposure

    CERC are partners in a new 5-year air quality (AQ) & health project that will develop a real-time, urban AQ modelling system capable of analysing and forecasting pollution levels in Hong Kong down to individual street level. PRAISE-HK (Personalised Real-time Air quality Information System for Exposure – ...

  • Polluted urban soil damages lime trees

    The impact of polluted urban soil on trees is highlighted in a recent study from Latvia. The researchers found that high salt levels from de-icing chemicals and nutrient imbalance in soil damaged lime trees growing in the city of Riga. Trees planted in cities are an important part of the urban landscape, providing a range of benefits, from enhancing biodiversity to promoting a feeling of ...

  • Cyclists map Antwerp air pollution with on-bike monitors

    Cyclists with pollution monitors and GPS trackers attached to their bicycles have produced detailed maps of Antwerp’s air quality, as part of a recent study. Their data show that a gap of just a few metres between cycle lanes and cars significantly reduces cyclists’ risk of inhaling high levels of ultrafine particle pollution. Personal ‘mobile monitoring’ is attracting ...

  • IMMISmt – monitoring system for air pollution and noise in cities

    IMMISmt is a real time monitoring system for air quality and noise. Based on online traffic data, measurements of air quality stations and weather data, IMMISmt calculates traffic induced emissions, background and total pollutant concentrations as well as noise levels within the streets as, e. g., hourly mean values. To do so, IMMISmt combines various models which are validated and widely used in ...

  • EPA releases final report on air toxics near Elm Street Elementary, no unsafe levels of diisocyanates, Benzene, or other VOCs detected (OH)

    U.S. Environmental Protection Agency Region 5 announced today that the final report based on the school air toxics monitoring data from Elm Street Elementary in Wauseon, Ohio, has been posted on the Agency’s website. Based on the monitoring results, EPA found no concern for risk of health problems from short-term or long-term exposures to diisocyanates, benzene, or other VOCs. Because no ...

  • Inauguration of Bangladesh Air Pollution Management Project

    6 Aug 2010 Bangladesh is suffering from some of the world's worst urban air quality problems. Particularly in the non-monsoon period the concentrations of particulate matter regularly exceed proposed standards. The larger cities such as Dhaka and Chittagong have major traffic issues which represent a source of the air quality problems, while industrial sources such as steel mills, cement ...

  • Rethinking Carbon Dioxide: From a pollutant to an asset

    With global greenhouse gas emissions still on the rise, despite decades of talk about curbing them, maybe the time has come to think differently about the climate crisis. Yes, we need to burn less coal, oil and natural gas, but clearly fossil fuels are going to be around for awhile. So why not try to clean up the mess they make? That's what a handful of prominent scientists are trying to do by ...

  • Rickshaw research reveals extreme Delhi pollution

    The three-wheeled rickshaw lurched through New Delhi's commuter-clogged streets with an American scientist and several air pollution monitors in the back seat. Car horns blared. A scrappy scooter buzzed by belching black smoke from its tailpipe. One of the monitors spiked. Joshua Apte has alarming findings for anyone who spends time on or near the roads in this city of 25 million. The numbers are ...

  • Careful urban tree planting and pruning needed to reduce trapping of air pollution

    Careful planting and pruning is needed to ensure that air pollution in tree-lined streets is minimised, new research suggests. While planting trees in urban areas can have many benefits, such as enhancing biodiversity, trees can trap particulate matter pollution, say the study’s authors. Particulate matter (PM) air pollution is a component of vehicle exhaust emissions and PM2.5 (particles ...

  • 2016 reveals deadly dangers of air pollution

    Beijing, London, Mexico City, New Delhi and Paris are among the cities that have drawn attention for their dangerously high air pollution levels in 2016 - but they're not abne. The World Health Organisation (WHO) has confirmed that 92 percent of the world's urban population now live in cities where the air is toxic. In India, a study found that 41 Indian cities of more than a million people faced ...

  • Latest emission control technology could eradicate harmful air pollution hotspots

    Switching to the best available emission control technologies could eliminate 99% of particulate matter pollution ‘hotspots’, a new study suggests. The researchers reached this conclusion by expanding the local-scale capabilities of an existing computer model that estimates the effects of air pollution policies and control measures. Particulate matter (PM) pollution has been linked ...

  • London Takes Just Six Months to Break Annual Air Pollution Standards

    London has taken just six months to use up its annual "allowance" of poor air quality days allowed under EU air pollution rules, delaing a broadside to the UK Government"s insistences that London will be compliant with these same rules by the end of 2011. Under EU law the concentration of dangerous airborne particles know as PM10 cannot exceed 50 micrograms per meter cubed of air on more than 35 ...
