The occurrence of a range of regulated and emerging organic environmental contaminants was investigated in 182 samples of edible marine fish sampled mainly from UK marine regions, but extending northerly to the coast of Norway and south to the Algarve. These species (sprats, mackerel, turbot, halibut, herring, grey mullet, sea bass, grey mullet, sardines, etc.) are among those considered to be at the highest risk of contamination with regulated contaminants such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs, dioxins), and polychlorinated biphenyls (PCBs), but the occurrence of polybrominated diphenylethers (PBDEs) and polybrominated biphenyls (PBBs) was also investigated. Sub-sets of samples (50–75) were also analysed for emerging contaminants: polychlorinated naphthalenes (PCNs), polybrominated and mixed halogenated dibenzo-p-dioxins, dibenzofurans and biphenyls (PBDD/Fs, PXDD/Fs and PXBs) and perfluoroalkyl substances (PFAS). Contaminant occurrence varied with species and location, but all measured contaminants were detected, with sprats, sea bass, sardines, mackerel, and herring showing higher tissue concentrations. The concentrations of the different contaminants in the various samples were mapped utilising the GPS coordinate data of the capture locations to visualise spatial distribution levels. In terms of catch location, fish sampled from the coasts of southern Britain, north-western France and the Irish Sea appeared to contain proportionately higher levels of some contaminants - e.g. samples from the Irish Sea tended to show higher PCN concentrations, whereas higher levels of PCBs were observed in some fish sampled off the coasts of northern France. Similarly, samples of mullet from the southeast coast of UK showed much higher concentrations of BDE-99 than the other regions. In terms of occurrence trends, PCDD/F and PCB concentrations show a modest decline over the last decade but where limited background data is available for emerging contaminants, there is no evidence of downward trends.

在主要来自英国海洋地区的182种食用海鱼样本中，调查了一系列受管制和正在出现的有机环境污染物的发生，但这些样本向北延伸至挪威沿海，向南延伸至阿尔加维。这些物种（西鲱，鲭鱼，大比目鱼，大比目鱼，鲱鱼，灰mul鱼，鲈鱼，灰鱼，沙丁鱼等）被认为受管制污染物（如多氯二苯并对二恶英）污染的风险最高。和二苯并呋喃（PCDD / Fs，二恶英）和多氯联苯（PCBs），但也调查了多溴联苯醚（PBDEs）和多溴联苯（PBBs）的发生。还分析了样品的子集（50-75）中新出现的污染物：多氯萘（PCN），多溴和混合卤代二苯并对二恶英，二苯并呋喃和联苯（PBDD / F，PXDD / F和PXB）以及全氟烷基物质（PFAS）。污染物的发生随物种和位置的不同而变化，但所有检测到的污染物均被检测到，鲱鱼，鲈鱼，沙丁鱼，鲭鱼和鲱鱼显示出较高的组织浓度。利用捕获位置的GPS坐标数据绘制各种样品中不同污染物的浓度，以可视化空间分布水平。就渔获物的位置而言，从英国南部，法国西北部和爱尔兰海的海岸采样的鱼似乎含有比例较高的某些污染物-例如，从爱尔兰海采样的鱼往往显示较高的PCN浓度，而在法国北部沿海一些鱼类中观察到多氯联苯含量较高。同样，来自英国东南海岸的鱼样本显示的BDE-99浓度比其他地区高得多。就发生趋势而言，在过去十年中，PCDD / F和PCB的浓度略有下降，但是对于新兴污染物，背景数据有限，没有下降趋势的证据。
