Benzotriazole are increasingly reaching rivers
Institute of Meteorology and Water Management (IMGW) states that benzotriazole, commonly used to slow down the corrosion process in the automotive industryM, aviation and chemical, “have recently become micro -cleansing more and more often present in the aquatic environment.” Latest The research brought disturbing results.
They get into the agricultural environment
IMGW He emphasizes that although these compounds are “identified mainly in highly urbanized areas”, the latest research carried out in the wool river basin They were also confirmed by their presence in an agricultural environment. This is the result wash interdisciplinary research team, which also includes IMGW experts. The results were published in the Water Resources and Industry magazine.
“Threat to ecosystems”
As part of the analysis, the content of benzotriazols in river water, surface flow, bottom sediments and suspension was evaluated. “Water pollution is a long -lasting global problemand micro -cleansing pose a threat to the ecosystems and human health ” – it was emphasized in the study. IMGW says that the key tool supporting” spatial and time analysis of pollution concentrations “was the SWAT model (Soil and Water Assessment Tool), which enabled flows and identification of sources of emissions throughout the sink.
IMGW: Knowledge about the mechanisms of transporting micro -cleanes
Samples were taken in October 2022 and January 2023, benzotriazole was discovered in virtually each of them. “The obtained results make up a significant contribution to the development of tools supporting the quality of surface water, especially in context the spread of substances considered to be durable and potentially harmful to the aquatic environment” – emphasizes IMGW. The Institute adds that the study has allowed to deepen knowledge about the mechanisms of transporting micro -cleanes” in catchments with varied land use, also outside urban areas. ”
