本文就如何使用被动采样法(PSM)改进沉积物中疏水性有机化学品的暴露评估提供了实用指南，该方法以自由溶解浓度(CFree)为目标。为特定应用选择PSM的主要考虑因素包括清楚地描述CFree的测量目标、是否需要基于实验室的“异地”应用和/或基于现场的“现场”应用，以及最终哪种PSM最适合实现测量目标。定义了适当校准和验证PSM的指导方针，包括使用聚合物-水分配系数的临时值、确定平衡状态和确认非耗尽测量条件。描述了一个假想的例子，以说明PSMS提供的自由基测量如何减少在评估被多环芳香族碳氢化合物污染的沉积物的麻醉毒性时的不确定性。文章最后对未来的研究进行了讨论，这些研究将提高利用PSMS进行的CFree测量的质量和稳健性，为支持风险评估和污染沉积物管理决策提供可靠的科学依据。综合环境评估马纳格2014；10：210-223。©2014作者。综合环境评估和管理，由威利期刊公司代表SETAC出版。
This article provides practical guidance on the use of passive sampling methods (PSMs) that target the freely dissolved concentration (Cfree) for improved exposure assessment of hydrophobic organic chemicals in sediments. Primary considerations for selecting a PSM for a specific application include clear delineation of measurement goals for Cfree, whether laboratory-based “ex situ” and/or field-based “in situ” application is desired, and ultimately which PSM is best-suited to fulfill the measurement objectives. Guidelines for proper calibration and validation of PSMs, including use of provisional values for polymer–water partition coefficients, determination of equilibrium status, and confirmation of nondepletive measurement conditions are defined. A hypothetical example is described to illustrate how the measurement of Cfree afforded by PSMs reduces uncertainty in assessing narcotic toxicity for sediments contaminated with polycyclic aromatic hydrocarbons. The article concludes with a discussion of future research that will improve the quality and robustness of Cfree measurements using PSMs, providing a sound scientific basis to support risk assessment and contaminated sediment management decisions.
