Contaminants of emerging concern were measured in mussels collected along the California coast in 2009-2010. The seven classes were alkylphenols, pharmaceuticals and personal care products, polybrominated diphenyl ethers (PBDE), other flame retardants, current use pesticides, perfluorinated compounds (PFC), and single walled carbon nanotubes. At least one contaminant was detected at 67 of the 68 stations (98%), and 67 of the 167 analytes had at least one detect (40%). Alkylphenol, PBDE, and PFC concentrations increased with urbanization and proximity to storm water discharge; pesticides had higher concentrations at agricultural stations. These results suggest that certain compounds; for example, alkylphenols, lomefloxacin and PBDE, are appropriate for inclusion in future coastal bivalve monitoring efforts based on maximum concentrations >50 ng/g dry weight and detection frequencies >50%. Other compounds, for example PFC and hexabromocyclododecane (HBCD), may also be suggested for inclusion due to their >25% detection frequency and potential for biomagnification.
2009-2010 年，在加利福尼亚沿海采集的贻贝中检测到了新出现的关注污染物。这七类物质包括烷基酚、药品和个人护理产品、多溴联苯醚（PBDE）、其他阻燃剂、当前使用的农药、全氟化合物（PFC）和单壁碳纳米管。在 68 个监测站中的 67 个（98%）检测到了至少一种污染物，在 167 种分析物中有 67 种（40%）至少检测到了一种。烷基酚、PBDE 和 PFC 的浓度随城市化和靠近雨水排放而增加；在农业站，农药的浓度更高。这些结果表明，某些化合物，例如烷基酚、洛美沙星和 PBDE，适合包含在未来的沿海双壳类贝类监测工作中，基于最大浓度>50ng/g 干重和检测频率>50%。其他化合物，例如 PFC 和六溴环十二烷（HBCD），也可能因其>25%的检测频率和潜在的生物放大而被建议包含在内。
