Three passive sampling devices (PSDs), polar organic chemical integrative samplers (POCIS), polyethylene devices (PEDs), and solid-phase microextraction (SPME) samplers were used to sample a diverse set of chemicals in the coastal waters of San Francisco Bay and the Southern California Bight. Seventy one chemicals (including fragrances, phosphate flame retardants, pharmaceuticals, PAHs, PCBs, PBDEs, and pesticides) were measured in at least 50% of the sites. The chemical profile from the San Francisco Bay sites was distinct from profiles from the sites in the Southern California Bight. This distinction was not due to a single compound or class, but by the relative abundances/concentrations of the chemicals. Comparing the PSDs to mussel (Mytilus spp.) tissues, a positive correlation exists for the 25 and 26 chemicals in common for the PEDs and SPME, respectively. Diphenhydramine was the only common chemical out of 40 analyzed in both POCIS and tissues detected at a common site.
三种被动采样器（PSD），即极性有机化学综合采样器（POCIS）、聚乙烯设备（PED）和固相微萃取（SPME）采样器，被用于采集旧金山湾和南加州湾沿海水域的多种化学物质。在至少 50%的采样点中，共检测到 71 种化学物质（包括香料、磷系阻燃剂、药物、多环芳烃、多氯联苯、PBDE 和农药）。来自旧金山湾采样点的化学物质特征与南加州湾采样点的特征明显不同。这种区别不是由单个化合物或化合物类别造成的，而是由化学物质的相对丰度/浓度决定的。将 PSD 与贻贝（Mytilus spp.）组织进行比较，PED 和 SPME 分别有 25 种和 26 种共同的化学物质呈正相关。在 POCIS 和组织中分析的 40 种化学物质中，只有一种共同的化学物质——苯海拉明在一个共同的地点被检测到。
