Manta nets are commonly used for microplastics sampling although a number of limitations have emerged. In this study we compare the manta net to an innovative microplastic sampler, referred to as MuMi, registered as utility model. The results highlight the large variability that can exist in the outcomes of the different studies due to the lack of harmonization between methods and the differing factors such as sampling mesh size, representativeness or reproducibility of the sampling volumes. Control over the filtered volume is an issue to be improved in trawl sampling methods, while in the MuMi sampler the control over the sampling depth could be improved. Still, MuMi represents a highly advantageous sampling system in terms of ease of operation, lower cost, smaller microplastics target size and greater precision, all while maintaining the representativeness of the collected samples.
尽管已经出现了一些局限性，但曼塔网通常用于微塑料采样。在本研究中，我们将曼塔网与一种创新的微塑料采样器（称为MuMi，已注册为实用新型）进行了比较。结果表明，由于方法之间缺乏协调性以及不同因素（如采样网眼尺寸、采样体积的代表性或可重复性），不同研究的结果可能存在很大差异。在拖网采样方法中，对过滤体积的控制是一个有待改进的问题，而在MuMi采样器中，对采样深度的控制可以改进。尽管如此，MuMi在操作简便、成本较低、微塑料目标尺寸较小和精度较高方面代表了一种非常有利的采样系统，同时保持了所采集样品的代表性。
