Climatological study of the acidic mist on the Kushiro Marsh.

在这项研究中，对位于久路沼泽南端的久路市大浪市的海岸和沼泽进行了雾酸度测量，以揭示酸雾的存在。作为雾出现的指标的能见度，在大浪久路国立理工学院的屋顶上被连续观测到。同时，使用气象气球从空气中收集雾并测量酸度。由于在海岸和沼泽之间有一个大型造纸厂，所以通过造纸厂对沿海到湿地的雾(主要是南风)和从沼泽到海岸的雾(主要是北风)进行分析。因此，风向对酸度的影响并不明显。北风和南风中雾的酸度最有可能是PH值约为3.5。

In this research, fog acidity is measured both on the coast and on the marsh at Otanoshike, Kushiro city, which is located at the southern end of Kushiro Marsh, to reveal the presence of acid fog. Visibility, which is used as the index for the appearance of the fog, is continuously observed on the rooftop of Kushiro National College of Technology in Otanoshike. At the same time, fog is collected from the air using a weather balloon and the acidity is measured. Since a large-scale paper mill is in between the coast and the marsh, analyses are performed for the fog from the coast to the marsh through the mill(mainly in the south wind) and that from the marsh to the coast through the mill(mainly in the north wind). As a result, no clear difference in the acidity by the direction of the wind appeared. Most likely acidity of the fog in both the north and the south wind is pH of about 3.5.
