The aim of our study is to estimate the abundance and sources of floating microplastics (MPs) along a coastal lagoon ecocline in a marine conservation unit (MCU) for implementing effective prevention and mitigation actions in South Brazil. MPs were sampled monthly, and the abundance and size were determined for hard solids, soft plastic, plastic filaments, and paint fragments. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) analysis was performed, and the MPs were classified as polyethylene, polyester, polypropylene, polybutadiene, and polystyrene. Downstream areas (outside of the MCU) showed high levels of MPs, during the winter, due to low precipitation and the predominance of S/SE winds. During summer, precipitation increases, and MPs are exported with surface runoff, resulting in lower level of MPs. Outside MCU areas, a high concentration of tourism houses, commercials, and artisanal fisheries were observed, which could contribute to all types of plastic debris found in our study.
我们的研究目的是估算南巴西南部一个海洋保护区（MCU）沿海泻湖生态梯度带内漂浮微塑料（MPs）的丰度和来源，以便采取有效预防和缓解措施。每月对 MPs 进行采样，并确定硬固体、软塑料、塑料长丝和油漆碎片的丰度和大小。采用衰减全反射傅里叶变换红外光谱（ATR-FTIR）分析，并将 MPs 分类为聚乙烯、聚酯、聚丙烯、聚丁二烯和聚苯乙烯。冬季，由于降雨量低和 S/SE 风盛行，MCU 外部（外部）区域的 MPs 水平较高。夏季，降雨量增加， MPs 随地表径流被输出，导致 MPs 水平较低。在 MCU 外部区域，观察到大量的旅游房屋、商业和手工渔业，这可能导致我们研究中发现的所有类型的塑料碎片。
