In this survey eighty-seven samples of consumption fish comprising mainly of salmon, pike, eel, herring, whitefish, sea-trout, perch, pike-perch, mackerel, cod, flounder, plaice and sole collected between 1992-1993 have been analysed for the levels of chlorinated pesticides and polychlorinated biphenyls (PCBs). Considering the diversity in the sizes and assortment, locations, and time of catch, the samples are deemed to represent the normal fish variety available to the local people at various seasons of the year. Virtually all the samples contained CB-153 levels below the new established maximum limit of 0.1 mg/kg fresh weight. Results are compared with those obtained between 1985 and 1993. Neither the total PCB (on fat weight basis) nor CB 153 as a marker showed any clear trend for most of the fish species analysed, particularly for the short period 1991-1993. The pesticides, on the other hand, showed a rather good downward trend up till 1991; some of them seem to have virtually attained a steady state after 1991.
在本次调查中，对1992年至1993年间采集的87份食用鱼样本进行了分析，这些样本主要包括鲑鱼、梭子鱼、鳗鱼、鲱鱼、白鱼、海鳟、鲈鱼、梭鲈、鲭鱼、鳕鱼、比目鱼、鲽鱼和鳎鱼，以检测其中有机氯农药和多氯联苯（PCBs）的含量。考虑到样本在大小、种类、捕捞地点和时间上的多样性，这些样本被认为代表了当地居民在一年中不同季节可获得的正常鱼类品种。几乎所有样本中CB - 153的含量都低于新设定的0.1毫克/千克鲜重的最大限量。将结果与1985年至1993年间获得的结果进行了比较。对于大多数分析的鱼类品种，无论是总多氯联苯（以脂肪重量计）还是作为标志物的CB 153，在1991 - 1993年这一短时期内都没有显示出任何明显趋势。另一方面，农药含量在1991年之前呈现出相当明显的下降趋势；其中一些在1991年之后似乎实际上已达到稳定状态。
