Industrial activities are sources of high emission rates of particulate matter. The existence of many such industrial plants close to a densely populated area can have a severe effect on human health. The effects can be even worse when these emissions are added to existing background concentration levels. This study deals with the assessment of the primary particulate matter pollution caused by industrial activities close to the city of Thessaloniki in Greece. An atmospheric dispersion and regulatory model was employed, i.e. AERMOD from the US Environmental Pollution Agency. A new PM10 emission sources inventory was prepared for the main industrial plants of the area and the annual and monthly average concentrations from 2003 to 2007 were calculated. The results from AERMOD were validated against data from available monitoring stations and showed reasonably good agreement. It was estimated that industry contributes approximately 30% of primary PM10 on the western suburbs of the city and about 7% in the city centre. The effect of the wind direction was also studied and it was illustrated that the frequent southwest winds present higher concentration levels than the strong north ones.
工业活动是颗粒物高排放源。许多这样的工业工厂靠近人口密集区，会对人类健康产生严重影响。当这些排放物被添加到现有的背景浓度水平中时，影响可能会更严重。本研究涉及评估希腊塞萨洛尼基市附近工业活动造成的主要颗粒物污染。采用了大气扩散和法规模型，即来自美国环境保护署的 AERMOD。为该地区的主要工业工厂编制了新的 PM10 排放源清单，并计算了 2003 年至 2007 年的年平均和月平均浓度。AERMOD 的结果与现有监测站的数据进行了验证，结果显示一致性较好。据估计，工业对城市西部郊区的主要 PM10 贡献约为 30%，对市中心的贡献约为 7%。还研究了风向的影响，结果表明，频繁出现的西南风会导致比强北风更高的浓度水平。
