Abstract:
As international regulations on aquatic organism discharge in ships\' ballast water take effect, port state authorities will need a sampling device for compliance inspectors to potentially use for sample collection. Importantly, the device must be easily operable, quickly connectable to the main ballast water pipe, and reliable in collecting a representative sample of the ballast water flowing through the pipe. Existing sampling devices currently fall short in these aspects. Therefore, we\'ve developed, manufactured, and validated a new sampling skid. This design enables the regulation of flow velocity and flow rate, facilitating the simultaneous, convenient collection of organisms ≥50 μm and other biological samples. In this study, we conducted a comparative analysis of sampling outcomes between traditional net sampling devices, using land-based experiments to assess the accuracy and precision of the innovative sampling skid. The findings show that, despite significant differences in <10 μm organism concentrations, the sampling skid, as an alternative to traditional net and other skid devices, has demonstrated substantial potential and feasibility.
摘要:
随着关于船舶压载水中水生生物排放的国际法规生效,港口州当局将需要一个抽样设备,以便合规检查员可能用于样品收集。重要的是,该设备必须易于操作,可快速连接到压载水管,可靠地收集流经管道的压载水的代表性样品。现有的取样装置目前在这些方面不足。因此,我们已经开发,制造,并验证了一种新的采样橇。这种设计可以调节流速和流速,促进同时,方便收集≥50μm的生物体和其他生物样品。在这项研究中,我们对传统净采样装置之间的采样结果进行了比较分析,使用陆基实验来评估创新采样橇的准确性和精度。研究结果表明,尽管<10μm生物体浓度存在显著差异,取样橇,作为传统网和其他防滑设备的替代品,已经证明了巨大的潜力和可行性。
