Abstract
A current national critical issue is an increase of drifted garbage on Japanese coasts. Because of the accumulation of the garbage year after year, the coastal pollution issue has become critical for recent years. The large amount of the drifted garbage has made many Japanese coasts like a huge landfill. Some of the garbage is found to be drifted or floated from several neighbor countries such as China, Taiwan, South Korean and Russia, depending on the location of the coasts in Japan. On the other hand, not many policies to manage the costal environment have been established well. Therefore, the coastal pollution caused by the drifted garbage has been getting serious every year.
In this report, especially, some discussions are carried out about the problem of drifted garbage in Yaeyama islands of Okinawa, injurious chemical substances contained in drifted oil balls and the possibility of injurious chemical substances dissolved by the decomposition of drifted garbage. Then, I expect that the feasible processing system for treating the drifted garbage is developed in order to protect coastal and marine environment.
