Urban Particulate Matter 2.5 Mass Concentrations: A Comparison Between A Drive-Through And A Park Setting, Cheryl Robertson Jan 2006

Urban Particulate Matter 2.5 Mass Concentrations: A Comparison Between A Drive-Through And A Park Setting, Cheryl Robertson

Theses and Dissertations (Comprehensive)

The focus of this thesis was to determine if light-duty vehicles idling at drive-throughs elevated ambient PM 2.5 mass more than those emitted by natural sources at a near-by greenspace. Two low-volume samplers (MiniVols), obtained from the Meteorological Services of Canada Air Quality Processes Research Division (ARQP), were set up 1.4 km apart in the west end of Kitchener, Ontario between the months of August and November, 2002. Four diurnal sampling periods were conducted on various days to determine when PM 2.5 mass concentrations were higher and at which location. Although overall results determined that the control ...


An Analysis Of Community Forest Implementation In British Columbia, Canada, Ryan C. Bullock Jan 2006

An Analysis Of Community Forest Implementation In British Columbia, Canada, Ryan C. Bullock

Theses and Dissertations (Comprehensive)

The community forest is increasingly seen as an alternative to industrial forestry for its perceived potential to mitigate conflict in forest resource management and planning. Theoretically, a community-based approach affords the chance to assert local values, provide local benefits, and manage resources differently than established top-down approaches. Yet practical examples of community forest initiatives in Canada reveal a host of constraints. This research uses a multiple case study design to investigate the motivations for and challenges to implementing community forests in British Columbia, Canada. Observations are drawn from four case studies (Denman Island, Malcolm Island, Cortes Island, and Creston) in ...


Assessment And Classification Of A Modified Urban Stream: Schneider Creek, Kitchener, Ontario, J. Andrew Carnegie Jan 2006

Assessment And Classification Of A Modified Urban Stream: Schneider Creek, Kitchener, Ontario, J. Andrew Carnegie

Theses and Dissertations (Comprehensive)

This study has produced an assessment framework and classification designed specifically for urban modified streams. While many stream assessment frameworks do exist, most are designed for natural streams and as such have no provision for characteristics of urban streams such as concrete channelization, storm drains, and urban debris. Building upon previous assessment and classification schemes, both urban and natural, this framework satisfies this need. It strengths lie in its user-friendly, visual-based approach to assessment by employing representative photographs and qualitative information to aid the user. A total of ten variables were employed that are scaled on a spectrum of categories ...
