Abstract

In order to investigate the effect of dusts from opencut mines and cement factories on pH of the reservoir water, water soluble components in the falling dusts collected by the deposit gauge method were analyzed from February 1987 to February 1988 at 9 locations in Yukuhashi City, Fukuoka. The partial neutralization of acidic substances was shown to be caused by non-seasalt (nss-) alkaline calcium compounds in winter. The formation of magnesium hydroxide in the deposit gauges was confirmed as a characteristic phenomena in a cement industrial area. The nss-Cl- deposition at location No.4 was affected by HCl and HClO gas from water purification plant. In summer, the Sea of Suou was the dominant source of sea salt particles deposited in Yukuhashi City. In winter months, however, sea salt transported far from the Sea of Genkai by the prevailing westerly wind was found to be the dominant sea salt components.
