Iwo-yama in Miyazaki prefecture erupted on the 19th. After the eruption, arsenic, boron and so on exceeding the environmental standards are detected upstream of the Nagae River at the foot where the water is white and muddy. In the prefecture we surveyed, we call for “not growing living organisms” as an agricultural water etc. Also, at the Kawachi River in Isa-shi, Kagoshima Prefecture, which connects with the Sendai River, the canoe competition that was scheduled to be held on 29th has been canceled, and the big consecutive holidays events have been affected.
