这项研究调查了大陆环境中城市隔间（废水和总大气沉降物）和地表水的微塑料污染。这些对城市环境的首次调查证实了污水、淡水和大气沉降物中存在微塑料，并提供了100-5000 μ m范围内微塑料类型和尺寸分布的知识。大气沉降物总量（29-280个颗粒m（-2）/天（-1））首次突出显示了微塑料（主要是纤维）的存在。在废水中发现了高水平的纤维（260-320 x 10（3）颗粒m（-3））。在处理后的污水中，污染物显著降低至14-50 x 10（3）个颗粒m（-3）。在塞纳河中，使用两种取样装置收集大小塑料微粒：（一）浮游生物网（80微米网眼）和（二）曼塔拖网（330毫米网眼）。用浮游生物网进行的取样显示，纤维占优势，浓度范围为3至108个微粒m（-3）。在曼塔拖网取样期间发现了更大的微塑料形状和类型多样性，但浓度要低得多（0.28-0.47个颗粒m-3）。这种结合的方法可能是相关的，并在未来的研究中实施，以提供淡水中微塑料分布的准确概述。
This study investigates the microplastic contamination of both urban compartments (wastewater and total atmospheric fallout) and surface water in a continental environment. These first investigations on an urban environment confirm the presence of microplastics in sewage, fresh water and total atmospheric fallout and provide knowledge on the type and size distribution of microplastics in the 100-5000-mu m range. For the first time, the presence of microplastics, mostly fibres, is highlighted in total atmospheric fallout (29-280 particles m(-2) day(-1)). High levels of fibres were found in wastewater (260-320 x 10(3) particles m(-3)). In treated effluent, the contamination significantly decreased to 14-50 x 10(3) particles m(-3). In the River Seine, two sampling devices were used to collect both large and small microplastic particles: (i) a plankton net (80-mu m mesh), and (ii) a manta trawl (330-mm mesh). Sampling with the plankton net showed a predominance of fibres, with concentrations ranging from 3 to 108 particles m(-3). A greater diversity of both microplastic shapes and types was found during manta trawl sampling but at much lower concentrations (0.28-0.47 particles m(-3)). This combined approach could be relevant and implemented in future studies to provide an accurate overview of microplastic distribution in freshwater.
