翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Air pollution in British Columbia ： ウィキペディア英語版 Air pollution in British Columbia Air pollution is a concern in British Columbia, Canada because of its effects on health and visibility. Air quality is influenced in British Columbia (BC) by numerous mountain ranges and valleys, which complicate atmospheric pollution dispersion and can lead to high concentrations of pollutants such as particulate matter from wood smoke (especially during stagnant atmospheric conditions/inversions). ==Air quality in BC== Air quality in much of BC is good compared to many areas of North America. This is particularly true for cities in BC such as the Greater Vancouver area and Victoria, British Columbia.Valley communities (e.g. Golden) may experience periods of poor air quality, particularly during stagnant atmospheric conditions. Two communities currently exceed the federal air quality standards; Prince George for particulate matter (PM2.5) and the community of Hope (in the Lower Fraser Valley) for ozone. Other communities are close to the PM2.5 standard, such as Quesnel and Kamloops. Communities close to exceeding the standard for ozone include Chiliwack, Langley, Kamloops and others.Hourly air quality monitoring results are available for the Lower Fraser Valley (). Air quality information is available for the rest of the province from the Ministry of the Environment. The BC Lung Association produces an annual (State of the Air Report ) for BC. This report is a collaboration between the provincial, federal and regional governments responsible for air quality management in BC. An important recent consideration is the nearly complete replacement of the TEOM (Tapered Element Oscillating Microbalance) pollution measurement instruments once relied on by BC with newer SHARP FEM (Federal Equivalency Method) monitors. The TEOMs often under-reported particulate matter measurements by 50%. A process of colocation and auditing of operations will allow reliance on the new and higher readings. A more complete understanding of conditions will lead to a greater understanding of likely impacts and may drive increased regulatory efforts. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Air pollution in British Columbia」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
