In the bustling Sea of Marmara, a critical waterway connecting the Black Sea to the Aegean, a pressing environmental concern is making waves. Microplastics, those tiny, insidious fragments of plastic pollution, are turning up in alarming quantities in the littoral sediments along the coast. A recent study, led by Esra Billur Balcıoğlu İlhan from the Department of Chemical Oceanography at Istanbul University’s Institute of Marine Sciences and Management, sheds light on the extent of this problem and its implications for maritime industries.
The research, published in the Journal of Marine Science and Engineering, is the first of its kind to examine microplastic pollution along the entire shoreline of the Sea of Marmara and the Çanakkale Strait. The findings are stark: every station sampled showed some level of microplastic contamination, with the highest concentrations found near river discharges. “There are no areas with low pollution levels in the Sea of Marmara,” İlhan asserts, underscoring the ubiquity of the problem.
The study identified fibers and fragments as the most common shapes of microplastics, with blue being the dominant color. Polyethylene (PE) emerged as the most prevalent polymer type. The contamination levels were classified as moderate to high, with one station, Yenice, exhibiting very high pollution levels. The hazard index and pollution risk index values were equally concerning, with some regions classified as dangerous.
For maritime professionals, these findings are not just an environmental red flag but also a call to action. The presence of microplastics can have significant commercial impacts. They can accumulate in marine organisms, entering the food chain and potentially affecting fisheries and aquaculture. The tourism industry, which relies on pristine coastal environments, could also take a hit if pollution levels continue to rise.
However, the study also presents opportunities. The identification of hotspots near river discharges points to targeted areas for intervention. Maritime industries can play a pivotal role in implementing sustainable practices and supporting cleanup efforts. “The need to implement sustainable plans and measures to prevent pollution in the Sea of Marmara is urgent,” İlhan emphasizes. This could open doors for innovative technologies and services aimed at microplastic removal and waste management.
The study serves as a wake-up call, highlighting the urgent need for action to protect and ensure the sustainability of coastal ecosystems in the Sea of Marmara. For maritime sectors, it’s a clarion call to innovate, adapt, and contribute to the fight against microplastic pollution. After all, a healthy marine environment is not just an ecological imperative but also a commercial one.
