  • Gaseous pollutant dispersion around urban-canopy elements: wind tunnel case studies

    There is an evident lack of reliable and detailed in situ measurement data for verifying numerical predictions of atmospheric dispersion in the urban environment on sub-meso scales. Wind-tunnel studies of dispersion around typical elements of the urban canopy (isolated buildings, groups of buildings, street canyons) could provide valuable substitutes for field datasets. They can achieve a high ...

  • Biofiltration: An Innovative Technology for The Future

    Biofiltration refers to the biological transformation or treatment of contaminants present in the gas phase, usually air. The fact that air contaminants can be biodegraded by active bacteria has been known for quite some time. However, it is only in the last 10 years, that biofiltration has begun to emerge as an economically viable treatment process. Initially, biofiltration involved the use of ...

  • Proposed pollutant index to incorporate synergistic effects

    It is important to monitor daily outdoor pollution conditions in order to issue advisory notices for those of the population more susceptible to the effects of pollution. These conditions are currently conveyed to the public via a single number and descriptor, known as the Pollutant Standards Index (PSI). The objective of the present work is to improve on some of the shortcomings in the PSI. ...

  • Monitoring Airborne Contaminants in Workplace Atmospheres, Using Sampling Devices and GC or HPLC

    Workers' exposure to hazardous substances must be held within acceptable limits. Therefore, airborne contaminant vapor and particles (including aerosols) in industrial atmospheres must be monitored. In the United States, the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) offer, for many such substances, specific ...
