Oil pollution

Japanese: 油汚染 - あぶらおせん

The contamination of waters, especially the ocean, by oil is called oil pollution. Since the 1950s, the worldwide increase in maritime oil transport has led to an increase in the number of tankers, and the tankers themselves have become larger and larger. However, this has also led to an increase in the number of large-scale oil spills and dumping due to tanker accidents, and oil pollution has come to be recognized worldwide as a major marine pollution issue. Prevention measures were considered by IMCO (now the IMO), and in 1954 the International Convention for the Prevention of Pollution of Sea Waters by Oil was established.

Japanese:

油による水域，とくに海洋の汚染を油汚染という。1950年代以降世界的な石油の海上輸送の増大によって，タンカーの数量は増加し，またタンカーそのものも大型化の一途をたどった。一方，これに伴ってタンカーの事故による大量の油流出や油の投棄が増加し，油汚染が海洋汚染の重要な課題として世界的に認識されるようになった。防止対策はIMCO（イムコ）(現在のIMO)で検討され，54年には〈油による海水の汚濁の防止のための国際条約〉が成立した。
