Study on health effect of the highly-concentrated methylmercury exposure derived from a cetacean

我们调查了成年人接触甲基汞对健康的影响。研究对象是194名居住在太地町的居民，太地町是日本传统捕鲸的发源地。头发汞含量的几何平均值为14.9 μ g/g，头发汞含量与每日鲸鱼肉摄入量显著相关，表明太地居民通过摄入鲸鱼肉高度暴露于甲基汞。未观察到头发汞含量与神经预后之间的显著相关性。感觉皮层和小脑的NAA/ Cr比值正常，提示该区域未见明显的神经元丢失。全血汞与硒水平呈显著正相关，所有受试者的全血汞/硒摩尔比为

We investigated the health effects of MeHg exposure in adults. The subjects were 194 residents who resided in Taiji, the birthplace of traditional whaling in Japan. The geometric mean of the hair mercury levels was 14.9 µg/g and hair mercury levels significantly correlated with daily whale meat intake, suggesting that Taiji residents were highly exposed to MeHg by ingesting whale meat. No significant correlations between hair mercury levels and neurological outcomes were observed. NAA/ Cr ratio of the sensory cortex and cerebellum was normal in the MR spectroscopy, suggesting that there was no apparent neuronal loss in these regions. A significantly positive correlation between whole blood mercury and Se levels was observed and the whole blood mercury/Se molar ratios of all subjects were
