  • Roadside particulate levels at 30 locations in the Kathmandu Valley, Nepal

    Roadside particulate levels (PM10) at 30 locations throughout the Kathmandu Valley, Nepal are reported. There were seven sampling cycles from January to December 1999. PM10 levels ranged between 1000 and 6000 µ/m³ for 1-h sampling. There was no consistent trend in PM10 levels with respect to monitoring cycle, average precipitation or wind speed. There is no WHO ...

  • 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 ...

  • Characteristic study of particulates and metallic elements at an urban sampling site in Taichung, central Taiwan

    Atmospheric total suspended particulate concentrations and metallic element concentrations were measured at three locations, characteristic of urban, suburban and rural sites. The sampling period was from July 2000 to August 2000. The results indicated that the urban sampling site had the highest total suspended particulate concentrations (average 108.61µ1m³), followed by the suburban site ...

  • PM10 and Their Effect in Respiratory Diseases of Population in Mexicali, Mexico

    Summary Constant exposure to air contaminants may cause of respiratory illnesses and trigger cardiovascular problems. In the last years, norms have been proposed to reducing air pollution, nevertheless, diseases and death cases are still occurring. It seems that there is a relation between excessive levels of PM10 and the increment of acute respiratory infections (ARI). Mexican and American ...


  • EMEP-reports prepared in 2002

    NILU presents at the Steering Body of EMEP in the fall each year status reports of the work at the EMEP project. This year several reports have been produced for the EMEP Steering Body meeting in Geneva 1 to 4 September 2002. Special attention have been paid to particles and heavy metals. The nineteenth intercomparison of analytical methods within EMEP Analytical intercomparison of heavy metals ...

  • PrimasonicsTM Audiosonic Acoustic Cleaners Employ High Energy - Low Frequency Sound Waves in a Non-Intrusive, Highly Effective and Automatic Manner to Prevent Particulate Build Up and Maintaining Material Flow

    Operation: PrimasonicsTM Audiosonic Acoustic Cleaners comprise of a Wave Generator and differing Bell Sections. Compressed air enters the Wave Generator and forces the titanium diaphragm to vibrate thus creating a base tone. The varying bell sections amplify and convert this into a particular frequency depending on the application. Sound is best described as the passage of pressure fluctuations ...


  • Controlling Dust and Bioaerosols at a Biosolids Composting Faclity

    Studies at enclosed Longmont, Colorado project evaluate exposure level of employees. Operational changes reduce dust, endotoxin and A. Fumigatus by 90 percent. WHEN dealing with public health issues and composting, attention has been predominantly focused on potential exposure from the release of Aspergillus fumigatus (A. fumigatus) from composting facilities. Numerous studies were conducted to ...


  • New Advances in Wet Scrubbing Improvements in Efficiencies

    Of all the air pollution abatement technologies, wet scrubbing systems remain the most versatile and cost efficient. New, patented advances in venturi scrubbing of air particulate, aerosols and gases easily achieves removal efficiencies greater than 99% for particulate and aerosols less than 3 Fm. Sub-micron particles present a special concern because they cause (at the very least) irritation of ...

  • Emission Testing of Engines to be Installed in Non-Road Mobile Machinery

    The European Commission has founded a project on emission testing – 'Emission Testing of Engines to be installed in Non-Road Mobile Machinery'. The project was undertaken by Abgasprüfstelle Berlin-Adlershof GmbH in Germany. The work is a part of emission inventory of spark-ignition engines to be used as a basis for a future amendment of the Directive 97/68/EC. The inventory covers seven different ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of ...
