奈良県十津川村と北海道の新十津川町は、遠く離れていても密な交流を保っている。1889年に発生した十津川大水害に伴う集団移住を契機とする「母子の村」の縁が、130年の長きにわたり続いている。本研究では、十津川村と新十津川町の交流の履歴について、第二次世界大戦後を中心に概要を把握し整理した。その結果、両地域の交流の歩みは、特徴や状況の異なる4つの時期に区分できることが明らかになった。また、交流は地方自治体どうしにとどまらず、民間団体や学校教育へと広がりを見せており、このことが両地域間の交流の持続可能性を高めている。

1 0 0 0 OA Contaminations by Endocrine Disrupting Chemicals in Coastal Waters of the East China Sea

There are many chemicals that have estrogen like activity in natural envrionment, and are well known as endocrine disrupting chemicals (EDCs). These chemicals disrupt the endocrine system of wildlife and induce the abnormality of reproductive phenomena. Recently, many scientists reported that EDCs in the aquatic environment interfere with the reproductive process of wild fish. However, there are few information about that in Asian countries. We conducted the survey of contamination by environmental estrogens (EEs) of coastal areas in Korea, People’s Republic of China, and Japan using the wild grey mullet. The grey mullet were collected from five sites (Ansan, Jeju, Yeosu, Tongyeong, and Busan) in Korea, three sites (Zhonshan, Luchaogang, and Pudong) in P.R. China, and three sites (Nagasaki, Omuta, and Fukuoka) in Japan. Contamination by EEs was determined by measuring vitellogenin (VTG) levels in serum and identifying gonadal abnormalities histologically (i.e., testis-ova). In four sites in Korea (Ansan, Yeosu, Tongyeong, and Busan), one site (Luchaogang) in P.R. China, and two sites in Japan (Nagasaki and Fukuoka), serum VTG in immature and male grey mullet was detected at levels greater than 1.0 μg/mL, which is considered to be an abnormal level. Testis-ova was detected in many sites of all countries, except for Yeosu and Jeju Island in Korea. These results suggest that the coastal areas of East China Sea are contaminated with EDCs.
