Abstract：
The paper presents measurement data concerning the degree of acidification of precipitation collected during a 6-month measurement campaign carried out in an immediate vicinity of a power plant, where the cooling tower was used for discharging flue gases as a product of coal combustion. As reference, data obtained from parallel measurements carried out at a monitoring station considered as city background station were used. High acidity of precipitation was anticipated due to reactions of acid gases contained in the combustion gases with water, which already occur inside the cooling tower. The results have not confirmed this assumption. The pH value of the precipitation samples was significantly higher than the pH of rainwater at the background station located 18 km away from the power plant.
摘要：
本文介绍了在发电厂附近进行的为期6个月的测量活动中收集的降水酸化程度的测量数据，冷却塔用于排放作为煤燃烧产物的烟气。作为参考，使用了在被视为城市背景站的监测站进行的并行测量获得的数据。由于燃烧气体中含有的酸性气体与水的反应，预计沉淀的酸度很高。已经发生在冷却塔内部。结果没有证实这一假设。在距发电厂18公里的背景站，降水样品的pH值显着高于雨水的pH值。
