已知塑料碎片在海上会破碎，从而形成塑料的微观颗粒;即所谓的“微塑料”。由于其浮力和持久性，这些微塑料有可能通过水动力学过程和洋流广泛分散在海洋环境中。本研究调查了比利时不同地点（沿海港口、海滩和亚沿海地区）海洋沉积物中微塑料的存在和分布情况，在所有样品中均发现大量颗粒物，显示出微塑料在比利时沿海沃茨的广泛分布。在海港发现了最高浓度，在那里观察到的微塑料总浓度高达390个颗粒/千克干沉积物，比其他类似研究地区报告的最高浓度高15-50倍，沉积物岩心的深度剖面表明，海滩上的微塑料浓度反映了全球塑料产量的增加。(C)2011爱思唯尔有限公司保留所有权利。
Plastic debris is known to undergo fragmentation at sea, which leads to the formation of microscopic particles of plastic; the so called 'microplastics'. Due to their buoyant and persistent properties, these microplastics have the potential to become widely dispersed in the marine environment through hydrodynamic processes and ocean currents. In this study, the occurrence and distribution of microplastics was investigated in Belgian marine sediments from different locations (coastal harbours, beaches and sublittoral areas).Particles were found in large numbers in all samples, showing the wide distribution of microplastics in Belgian coastal waters. The highest concentrations were found in the harbours where total microplastic concentrations of up to 390 particles kg(-1) dry sediment were observed, which is 15-50 times higher than reported maximum concentrations of other, similar study areas.The depth profile of sediment cores suggested that microplastic concentrations on the beaches reflect the global plastic production increase.
