Muscle, lung, kidney and liver tissues of 45 bycatch and stranded cetaceans, including 14 Grampus griseus (Gg), 7 Kogia simus (Ks), 10 Lagenodelphis hosei (Lh), and 14 Stenella attenuata (Sa), were collected in the waters off Taiwan from 1994 to 1995, and from 2001 to 2012. Baseline concentrations (in μgg dry weight) of the cetaceans were lung (<0.05)=muscle (<0.05)<kidney (0.08±0.04)<liver (0.43±0.28) for Ag, and muscle (0.03±0.03)=lung (0.22±0.19)<liver (3.82±3.50)<kidney (16.22±18.81) for Cd. Unhealthy and critically dangerous Ag and Cd tissue concentrations in the toothed cetaceans are suggested. Marked high concentrations of Ag and Cd found in Gg and Lh are highly related to their squid-eating and deep diving habits. The highest ever recorded concentrations of liver-Ag and kidney-Cd were found in two Lh. These Taiwanese cetaceans indicate marked Ag and Cd pollution in the recent two decades in the western Pacific Ocean.
1994 年至 1995 年和 2001 年至 2012 年期间，在台湾水域捕获并搁浅的 45 头副渔获物和搁浅的鲸目动物（包括 14 头灰海豚（Gg）、7 头小抹香鲸（Ks）、10 头霍氏海豚（Lh）和 14 头短肢领航鲸（Sa））的肌肉、肺、肾和肝组织被采集。这些鲸目动物的基线浓度（以μgg 干重计）为：Ag 在肺组织中浓度最低（<0.05）=肌肉组织中浓度最低（<0.05）<肾组织中浓度（0.08±0.04）<肝组织中浓度（0.43±0.28）；Cd 在肌肉组织中浓度最低（0.03±0.03）=肺组织中浓度最低（0.22±0.19）<肝组织中浓度（3.82±3.50）<肾组织中浓度（16.22±18.81）。这表明齿鲸类动物的 Ag 和 Cd 组织浓度处于不健康和临界危险水平。Gg 和 Lh 组织中 Ag 和 Cd 浓度显著升高，这与它们摄食鱿鱼和深潜的习惯密切相关。在两只 Lh 中发现了肝组织中 Ag 和肾组织中 Cd 的最高记录浓度。这些台湾鲸目动物表明，在过去二十年中，西太平洋地区的 Ag 和 Cd 污染程度显著。
