概括

废旧的弹药会将有毒化学物质释放到波罗的海. 虽然通常低于毒性水平,但高度和未爆炸弹药的长期污染风险需要监测.

科学领域:

环境化学环境化学
海洋污染海洋污染
化学海洋学化学海洋学

背景情况:

全球沿海水域被遗留弹药和倾倒的爆炸物污染.
据估计,仅在德国的波罗的海海域就有30万弹药.
弹药含有有毒的爆炸性化学物质,如TNT,RDX和DNB,它们通过腐蚀入海水.

研究的目的:

为了量化德国波罗的海的弹药化学物 (MC) 度.
研究MCs在水,悬浮颗粒和沉积物中的分布.
为了建模TNT运输和评估长期污染潜力.

主要方法:

在波罗的海西南部 (2017-2018) 进行了详细的环境采样.
在水,悬浮颗粒和沉积物中测量MCs.
在通用河口运输模型 (GETM) 中开发和应用一个TNT模块.

主要成果:

在几乎所有水样中检测到弹药化学物质 (MCs),主要是溶解的形式.
基尔湾的TNT度最高;卢贝克湾的RDX和DNB度最高.
模拟的TNT分布与观察到的环境模式保持一致,验证了模型.
溶解的MC度大多低于急性/慢性毒性水平,但对于DNB.接近它们.
估计有3000公斤的溶解MCs存在,可能会持续污染800多年.

结论:

弹药化学污染在德国波罗的海地区普遍存在.
由于海底巨大的弹药库存,溶解的MCs构成潜在的长期风险.
进一步的监测和风险评估对于管理这种遗留污染至关重要.

关键词:

爆炸物是一种爆炸物.历史性的历史性的历史性的海军的弹药,海军的弹药.污染物的污染物这是RDX RDX.在TNT上播放.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Primary Production

Primary Production

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
