Microplastics are known to be an increasing component found within both marine sediments and the water column. This study carried out an initial assessment of the levels of microplastics present within the Solent estuarine complex, focusing specifically on the water column. A plankton net trawl survey was carried out, with samples analysed using visual observation and Fourier Transform Infrared Spectroscopy (FT-IR). The study identified significant quantities of plastics, ranging in shape, with hot spots found at confluence points within the estuary. Though the FT-IR analysis was inconclusive, the nature of the samples indicates the effect of oceanographic conditions on the prevalent types of microplastics found, which in turn identifies key local sources such as wastewater treatment plants and the plastics industry as being the dominant inputs.
微塑料是海洋沉积物和水柱中越来越常见的成分。本研究对索伦特河口复杂区域的微塑料水平进行了初步评估，重点关注水柱。进行了浮游生物网拖网调查，并使用视觉观察和傅里叶变换红外光谱（FT-IR）对样品进行分析。该研究发现了大量的塑料，形状各异，在河口的汇合点发现了热点。尽管 FT-IR 分析没有定论，但样品的性质表明海洋条件对发现的微塑料主要类型的影响，这反过来又确定了关键的本地来源，如污水处理厂和塑料工业，它们是主要的输入源。
