In-Depth Investigation of Organic Micropollutant Burden in the Dnipro River Basin in Ukraine During Wartime Utilizing High-Resolution Mass Spectrometry (HRMS) Workflows
Summary:
Anthropogenic activities significantly contribute to the introduction of organic micropollutants such as priority pollutants and emerging contaminants into the environment. Man-made environmental disasters, such as oil spills and the destruction of infrastructure during wartime, significantly increase the environmental pollutant burden of the environment at a rapid pace. Thus, systematic monitoring after ecological disasters is of utmost importance. On 6 June 2023, an explosion destroyed the Nova Kakhovka dam in southern Ukraine, causing one of Europe's biggest ecological disasters in decades. The collapse resulted in a massive release of water, sediments, and, subsequently, organic micropollutants into the Black Sea through the Dnipro River, potentially impacting the aquatic ecosystems.
The aim of this study is the in-depth investigation of the organic micropollutant burden in the Dnipro River basin and the Black Sea following the Nova Kakhovka dam collapse. Aiming to investigate the occurrence of organic micropollutants in the impacted ecosystem, surface water, seawater, groundwater, and sediment samples were collected in the framework of a monitoring campaign conducted immediately after the Nova Kakhovka dam breach and the ensuing flood. The analytes were extracted from the matrices using generic sample preparation protocols, whereas HRMS data were acquired by complementary chromatographic techniques coupled with HRMS instrumentation to facilitate the wide-scope target screening of more than 2,400 organic micropollutants. Afterwards, the results of the post-disaster sampling campaign were compared with data from previous sampling campaigns, conducted in the same region. In total, 146 organic micropollutants from various chemical classes were identified in the water and sediment samples. The temporal comparison of pollutant levels in the area indicated a consistent upward trend.
