The change of the chemical composition of sea water around the Expo Bah particularly stressed on the check of inorganic nutritive substances, has been surveyed for five times before and during the period of the Exposition. In general the nutritive substances in sea water such as ammonia and nitrite nitrogen increase along with the increase of the human activities on the beach. The ammonia gives the highest concentration on the August measurement due perhaps to the highest beach activities within the period of the Exposition, and then decrease after the season of the beach activities over. The concentrations of the nitrite nitrogen, however display the continuous increase even after the swimming season is over. This may probably be due to the highly contaminated bottom sediment at local area of the beach such as inland like bay of the Station 20 and 25, resulting the continuous increase of the nitrite nitrogen by the decompositions and the other chemical reaction of the contaminating substances in the sediment.

内容記述 The Expo Beach has been constructed at Motobu Peninsula as one of the establishments of the International Ocean Exposition Okinawa Japan, 1975. The change of the chemical composition of sea water around the Expo Bah particularly stressed on the check of inorganic nutritive substances, has been surveyed for five times before and during the period of the Exposition. In general the nutritive substances in sea water such as ammonia and nitrite nitrogen increase along with the increase of the human activities on the beach. The ammonia gives the highest concentration on the August measurement due perhaps to the highest beach activities within the period of the Exposition, and then decrease after the season of the beach activities over. The concentrations of the nitrite nitrogen, however display the continuous increase even after the swimming season is over. This may probably be due to the highly contaminated bottom sediment at local area of the beach such as inland like bay of the Station 20 and 25, resulting the continuous increase of the nitrite nitrogen by the decompositions and the other chemical reaction of the contaminating substances in the sediment. It is, therefore, said that the bottom sediment remains the residual contaminative aspect for the concentration of nitrite nitrogen for the considerable period of time beyond the beach season.
