TAILIEUCHUNG - AIR QUALITY MONITORING, ASSESSMENT AND MANAGEMENT_2

Human beings need to breathe oxygen diluted in certain quantity of inert gas for living. In the atmosphere, there is a gas mixture of, mainly, oxygen and nitrogen, in appropriate proportions. However, the air also contains other gases, vapours and aerosols that humans incorporate when breathing and whose composition and concentration vary spatially. Some of these are physiologically inert. Air pollution has become a problem of major concern in the last few decades as it has caused negative effects on human health, nature and properties | Part 2 Air Quality Assessment and Management 4 Nuisance Dusts -Validation and Application of a Novel Dry Deposition Method for Total Dust Fall Gary T. Hunt TRC Corporation Wannalancit Mills Lowell MA USA 1. Introduction Nuisance dust complaints received from residents living in the vicinity of a coal fired power plant in the eastern United States prompted development of a monitoring program to quantify the frequency of incidents as well as the magnitude of the problem if any . Nuisance dusts in this context defined as visible dust deposits on solid surfaces while regulated by some state and local agencies have no quantitative standards or guidelines associated with them that define acceptable levels concentrations in ambient air or deposited on surfaces. Methods historically used to measure and or characterize airborne dusts have included manual Wheeler . and . Stancliffe 1998. ASTM D6966-08. and automatic wipe sampling techniques Wheeler . and . Stancliffe 1998. use of adhesive tapes Wheeler . and . Stancliffe 1998. passive sampling using open faced containers Estokova A N. Stevulova and L. Kubincova 2010 ASTM D-1739-98 Reapproved 2004. James P. Lodge Jr Editor Lewis Publishers 1989. and vacuum or suction sampling apparatus Byrne . 2000. ASTM D-5438-05 2005. While all of these techniques have been employed for collection of surface dusts they were not suitable for the current application for one or more of the following reasons 1 not suitable for gravimetric measurements wipe sampling for example 2 designed for the collection of wet and dry dusts combined and not dry surface dusts only passive collection in open faced containers for example 3 qualitative characterization only of dry dusts present on surfaces adhesive tape sampling for example 4 ease in deployment and recovery at multiple stations simultaneously. In order to meet the needs of the monitoring program the preferred method was characterized as follows 1 ease in deployment and .
