| Research Abstract |
Sources of marine litter on the North Pacific coasts were compared by making use of an indicator item. The disposable lighter was chosen as an indicator, because the discharge area and location can be distinguished by characters printed on the surface of tank. Since April 2010 to March 2013, the collected sites were 307 beaches on the Japan (including Izu Islands and Ogasawara Islands), US (Midway Atoll, Hawaii Islands, West Coast), Taiwan, Northern Australia, and other coasts of North Pacific. The number of lighters collected for three years were 14,647. The lighters that flowed out from Honshu Pacific side area were recognized on the coasts of Izu and Ogasawara Islands. The souse of lighter collected on the coasts of Midway Atoll and Hawaii Islands is the same as Izu and Ogasawara Islands. However it was few the Japan lighter on the beach of West Coast and Taiwan. It was appeared that the Central area of North Pacific was strongly affected by marine litter from Japan and East Asia (China, Korea, Taiwan), however the marine litter from Japan doesn’t reach to West Coast and Taiwan.
