  • Office Printers Emit Ultra fine particle pollution

    We’ve heard quite a bit about particulate matter PM10s and PM2.5s as components of air pollution that we are exposed to on a daily basis. Recent research papers are highlighting the dangers of ultra fine particles (UFPs), which have a diameter of less than 0.1 micrometres (or 100 nanometres). By contrast, the diameters of particulate pollution from PM10s and ...

  • Elevated PM10 concentrations and high PM2.5/PM10 ratio in the Brussels Urban area during the 2006 car-free Sunday

    The results of the Car-Free Sundays in Brussels demonstrate the close relationship between the traffic and the presence of the gaseous pollutants such as NO, NO2, CO, CO2 and O3 in a traffic environment. The relationship with PM10 and PM2.5 seems to be much more complex. In fact, the PM10 and PM2.5 concentrations on the Car-Free Sunday 2006 were amongst the highest that year and they were three ...

  • Reduced PM2.5 in Trujillo, Peru, on El Dia Sin Autos (“The Day Without Cars”)

    Street-level and rooftop (three-story building) concentrations of particulate matter ≤2.5 µm in diameter (PM2.5) were measured in downtown Trujillo, Peru, in July and August 2003 to determine the PM2.5 concentration reduction on days with normal traffic conditions (32 days) versus a day when motor vehicles were temporarily banned from the downtown district (8:00 a.m. to 6:00 p.m., ...

  • EPA shifts PM2.5 PSD permitting policies

    On August 12, 2009, EPA created a significant stir in the regulated community when it issued an order that signals a significant shift in how the agency intends particulate matter with a diameter less than 2.5 micrometers (PM2.5) emissions to be regulated under the Prevention of Significant Deterioration (PSD) program. The order specifically applied to petitions filed by environmental groups ...

  • Characteristics of PM2.5 in rural areas of southern Jiangsu Province, China

    To understand pollution level and possible sources ofatmospheric fine particulates in rural areas of southern Jiangsu Province of China, samples of PM2.5 were collected and analyzed in Xueyan Town and Taihu Lake Station over three seasons from July 2002 to January 2003. The mass concentrations of PM2.5 and 14 principal component elements were obtained. The results showed that pollution of PM2.5 ...

  • PM10 and PM2.5 - legislation, measurement and control

    New standards for PM10 and PM2.5 in ambient air are being formulated in Europe and the USA. There is much controversy over this legislation, not only with respect to the stringent limits proposed, but also due to the many problems associated with ensuring compliance with standards for a pollutant which is so poorly understood. New sampling and analysis techniques ...
