1999年2月，从日本六个城市的市场上购买了各种齿鲸和神秘鲸的鲸类产品。经过遗传分析，对61种产品进行了重金属（Hg, Cd, Pb）和有机氯化合物（pcb, DDTs, HCHs， HCB和dieldrin）的分析。以湿重为基础（n=19），齿鲸产品中的汞和甲基汞含量分别为2.13 ppm和1.36 ppm，而神秘鲸产品中的汞含量低于0.09 ppm。齿鲸和鲸类产品（北太平洋小须鲸）中PCB的平均含量分别为2.80 ppm （n = 19）和0.76 ppm (n = 19)，而来自南大洋的鲸类样品中的PCB含量低于0.02 ppm。数据表明，来自北太平洋的鲸类动物的饮食习惯可能导致消费者超过甲基汞和多氯联苯的允许摄入量。
Cetacean products from a variety of odontoceti and mysticeti whales were purchased from markets in six cities across Japan in February 1999. After genetic analyses, 61 products were analyzed for heavy metals (Hg, Cd, Pb) and organochlorine compounds (PCBs, DDTs, HCHs, HCB, and dieldrin). Levels of mercury and methylmercury in odontoceti products were 2.13 ppm and 1.36 ppm on the wet weight basis (n=19), respectively, whereas the mercury level in mysticeti products was less than 0.09 ppm. Average PCB levels in odontoceti and mysticeti products (North Pacific minke whales) were 2.80 ppm (n = 19) and 0.76 ppm (n = 19), respectively, whereas the levels in mysticeti samples from the southern ocean were below 0.02 ppm. The data indicate that the dietary habit of cetaceans from the North Pacific Ocean could result in consumers exceeding the permitted intake for methylmercury and PCBs.
