전남연안 영광, 신안, 진도, 완도, 고흥, 여수 6곳에서 2010년 7월 하계와 2012년 7월 하계까지 연구지역 현장에서 5회에 걸쳐 외국기인 해안표착쓰레기의 분포와 기원을 파악하기 위하여 외국기인 해안표착쓰레기 중 식별 가능한 상표를 기준으로 기원을 분류 하였으며, 이 중 중국기인은 지역별로 정밀분석을 실시하였다.조사기간 중 수거된 해안표착쓰레기 성상별 개수로는 고무가 1,320개로 2.5%, 금속이 952개로 1.8%, 유리가 1,252개로 2.4%, 스티로폼이 16,433개로 31.6%, 종이류가 359개로 0.7%, 플라스틱이 27,438개로 52.7%, 의류 및 천이 366개로 0.7%, 기타가 3,964개로 7.6%로 총 52,084개로 조사되었다. 이 중 외국기인 해안표착쓰레기 성상별 개수로는 고무가 417개로 3.2%, 금속이 282개로 2.2%, 유리가 381개로 2.9%, 스티로폼이 3,193개로 24.7%, 종이가 81개로 0.6%, 플라스틱이 8,858개로 60,8%, 의류 및 천이 86개로 0.7%, 기타가 618개로 4.8%로 총 12,916개로 조사되었다. 외국기인 해안표착쓰레기의 국가별 분류에서는 중국이 10,162개로 78.7%, 일본이 93개로 0.7%, 타이완이 88개로 0.68%, 말레이시아가 31개로 0.2%, 베트남이 20개로 0.2%, 홍콩이 15개로 0.1%, 인도네시아가 10개로 0.1%, 태국이 6개로 0.05% 순으로 조사되었다.
Occupying 50% of the sea of South Korea, coastal zones in Chonnam province have been polluted by ocean floating wastes(OFWs) derived from not only South Korea, but also from other countries. Understanding sources, distributions and characteristic of these wastes, especially the foreign derived wastes(FDWs) are very important for monitoring the pollution status of the coastal zones. Therefore, we carried out this study to investigate the distribution and origin of the ocean floating wastes derived from foreign countries on 6 coastline areas in Chonnam province including Yeongkwang, Sinan, Jindo, Wando, Koheung and Yeosu. The study was conducted from July 2010 to July 2012 with 5 sampling times in total. Out of 52,484 collected OFWs during the survey, the number of floating wastes characterized by rubber, metal, glass, styrofoam, paper, plastic, clothing and cloth and others were 1,320 (2.5%), 952 (1.8%), 1,252 (2.4%), 16,433 (31.6%), 359 (0.7%), 27,438 (52.7%), 366 (0.7%) and 3,964 (7.6%), respectively. Additionally, the observed FDWs filled up 24.80% of the total collected OFWs and its quantity was 12,916 involving 8,858 plastic things (60.8%), 3,193 styrofoam things (24.7%), 414 rubber things (3.2%), 381 glass things (2.9%), 282 metal things (2.2%), 86 clothing and cloth things (0.7%), 81 paper things (0.6%) and 618 others (4.7%). Separating the counted FDWs by country, the percentage of China, Japan, Taiwan, Malaysia, Vietnam,Hongkong, Indonesia and Thailand was 78.7%(10,162 things), 0.7% (93 things), 0.6% (88 things), 0.2% (31 things), 0.2% (20 things), 0.1% (10 things) and 0.05% (6 things). Hence, China was found as the country that contributed highest proportion of FDWs and plastic wastes was the dominant in the coastline areas of Chonnam province. The investigated coastal zones were affected by different currents and seasonal winds. Yellow Sea warm current (in summer) and Korea southern-west coast current (in winter) affect the western coast zones including Yeongkwang and Sinan. Tsushima warm current (in summer) and Korea southern-west coast current (in winter) affect the southern-west coastal zones including Jindo and Wando. Tsushima warm current (in summer) and north Korea cold current (in winter) affect the southern coast zones including Koheung and Yeosu. And seasonal winds also affected FDWs. In conclusion, this study has demonstrated the distributions and origins of shoreline FDWs in the coastal zones of Chonnam province, south Korea.
