微塑料在环境中无处不在，经常被生物摄入，并可能造成潜在危害。一系列研究发现，沙滩上的微塑料含量很高。然而，这些研究在方法上存在相当大的差异。方法上的差异目前限制了比较，因为没有微塑料取样或提取的标准程序。通过详细的回顾，我们确定了整个文献中的关键采样和提取程序。我们发现采样深度、采样位置、重复提取次数和沉淀时间是变化的关键参数。接下来，通过案例研究，我们确定这些差异是否以及在多大程度上影响研究结果。通过调查案例研究中文献中确定的常见做法，我们提供了从海滩沙子中取样和提取微塑料的标准操作程序。(C) 2016 Elsevier Ltd.版权所有。
Microplastics are ubiquitous in the environment, are frequently ingested by organisms, and may potentially cause harm. A range of studies have found significant levels of microplastics in beach sand. However, there is a considerable amount of methodological variability among these studies. Methodological variation currently limits comparisons as there is no standard procedure for sampling or extraction of microplastics. We identify key sampling and extraction procedures across the literature through a detailed review. We find that sampling depth, sampling location, number of repeat extractions, and settling times are the critical parameters of variation. Next, using a case-study we determine whether and to what extent these differences impact study outcomes. By investigating the common practices identified in the literature with the case-study, we provide a standard operating procedure for sampling and extracting microplastics from beach sand.
