1917年沉没于丹麦附近的德国潜艇UC-30至今仍在向海洋持续泄漏TNT。1这艘潜艇于1917年4月19日被英国水雷击中沉没，船上27名船员全部遇难，1潜艇当时装载18枚水雷和6枚鱼雷。1研究人员已在野生动物、海床和水柱中检测到TNT的痕迹，表明污染正在北海周围扩散。1
丹麦海域的沉船问题远不止UC-30一艘。1丹麦环保部门发现该海域共有10127艘沉船，其中约15%源自1910年至1920年和1940年至1945年两个战争时期。12024年的一份报告由丹麦环保局委托完成，用于评估这些沉船是否符合欧盟水框架指令的要求。1德国已投入大量资金从波罗的海打捞部分沉船和二战弹药。1
应对这一环保挑战，REMARCO项目正在测试海底机器人技术以定位危险弹药并监测沉船恶化情况。1丹麦科学家Katrine Juul Andresen教授表示："TNT污染肯定正在发生。问题在于影响程度有多大以及污染对海洋环境的影响范围有多远。"1科学家警告，类似沉船可能构成日益严重的海洋环保风险。1
The German submarine UC-30, which sank near Denmark during World War I, continues to discharge TNT into the ocean, contaminating surrounding waters, seafloor, and marine life.1 The vessel was struck by a British naval mine and sank on April 19, 1917, killing all 27 crew members aboard.1 The submarine was carrying 18 naval mines and six torpedoes at the time of its sinking.1
Scientists have detected TNT traces throughout the marine environment in the vicinity of the wreck.1 A 2024 report commissioned by the Danish Environmental Protection Agency identified approximately 10,127 sunken vessels in Danish waters, with roughly 15 percent originating from the two world wars—specifically from 1910-1920 and 1940-1945.1 The study assessed these wrecks in accordance with requirements of the European Union Water Framework Directive.1
Research efforts to address the threat are underway through the REMARCO project, which is testing underwater robotic technology to locate dangerous ammunition and monitor the deterioration of shipwrecks.1 Germany has already invested significant resources in salvaging some wrecks and recovering World War II ammunition from the Baltic Sea.1 According to Professor Katrine Juul Andresen, "TNT contamination is definitely occurring. The question is how extensive the impact is and how far the pollution spreads in the marine environment."1
