摘要

空气污染是当今主要的环境问题之一,特别是对于发展中国家,如孟加拉国和布里克菲尔德已被确定为该国主要城市的重要污染源。验证有效的空气质量模型在孟加拉国条件下的适用性,特别是对砖场污染的适用性是这项工作的主要关注点。为了实现这一目标,对环境污染物浓度进行了实验测量,并与使用工业源复合体(ISC3)模型建模产生的结果进行了比较。在Savar Amin Bazar附近的41个砖窑群的不同地点进行了空气采样,使用Gastec管和高容量采样器。气体污染物采用Gastec管,总悬浮颗粒物(TSP)采用High volume进样器。气态污染物包括二氧化硫、一氧化碳和碳氢化合物。将不同地点不同天数的污染物数据与ISC3模拟值进行比较。工业源复合体(ISC3)模型被发现非常有效和适用于孟加拉国砖场污染的气体污染物和颗粒物质,这表明了在孟加拉国将该模型用于不同条件和目的的前景。从实验数据和模拟数据来看,颗粒物是该地区最重要的污染物,急需治理。

Applicability of Air pollution Modeling in a Cluster of Brickfields in Bangladesh
Air pollution is one of the major environmental problems now days, especially for developing countries such as Bangladesh and Brickfields have been identified as a vital pollutant source of the major cities of the country. Verification of the applicability of an effective air quality model in Bangladesh condition, especially for brickfield pollution was the main concern of this work. To achieve that objective, ambient pollutant concentrations were measured experimentally and compared with the results generated through modeling using Industrial Source Complex (ISC3) model. Air sampling was done at different locations in a cluster of brickfields of 41 brick kilns near Amin Bazar, Savar using Gastec tubes and High volume sampler. Gastec tubes were used for gaseous pollutants and High volume sampler was used for Total Suspended Particulates (TSP). Gaseous pollutants included Sulfur dioxide, Carbon monoxide, and Hydrocarbons. Those pollutant data at different locations on different days were compared with simulated value generated through ISC3. Industrial Source Complex (ISC3) model was found very effective and appropriate both for gaseous pollutants and particulate matter for brickfield pollution in Bangladesh and which indicates the prospect of utilizing this model for different condition and purposes in Bangladesh. From both the experimental and simulated data, particulate matter had been identified as the most important pollutant in that region which is urgently needed to be taken care of.
