| Research Abstract |
Concentration level of organic tin compounds in sediment was investigated at local fishing ports of northern part of Kyushu, southern part of Korea, Kanto region, east coast of Tohoku, main island of Okinawa, and southwest area of Hokkaido. It was found out that the concentration of sediment in the port equipped with repaint facility was higher than the sediment in the other port without the facility at every area. The concentration level was divided into the high pollution level in the previous reports. The copper pyrithione, which was the main element of alternate antifouling paint, was detected from the environmental samples in the local fishing port.
