对日本海岸捕获的红雪蟹（Chionoecetes japonicus）中的总汞（T-Hg）和甲基汞（MeHg）浓度进行了分析。生肌肉中 T-Hg 浓度范围为 0.03 至 0.56 mg/kg（平均值：0.21 mg/kg），煮熟肌肉中 T-Hg 浓度范围为 0.02 至 0.74 mg/kg（平均值：0.27 mg/kg）。原始肌肉中的甲基汞浓度范围为 0.04 至 0.54 毫克/千克（平均值：0.20 毫克/千克）。 MeHg 与 T-Hg 的平均比率为 0.88。研究发现螃蟹体重与 T-Hg (r = 0.488) 和 MeHg (r = 0.490) 浓度显着相关（p
The total mercury (T-Hg) and methylmercury (MeHg) concentrations in red snow crabs (Chionoecetes japonicus) caught off the coast of Japan were analyzed. The T-Hg concentration ranged from 0.03 to 0.56 mg/kg (mean: 0.21 mg/kg) in the raw muscle, and 0.02 to 0.74 mg/kg (mean: 0.27 mg/kg) in the boiled muscle. The MeHg concentration ranged from 0.04 to 0.54 mg/kg (mean: 0.20 mg/kg) in the raw muscle. The mean ratio of MeHg to T-Hg was 0.88. The crab body weight was found to significantly correlate with the concentrations of T-Hg (r = 0.488) and MeHg (r = 0.490) (p
