| 摘 要： | 为了解中华绒鳌蟹不同可食组织（性腺、肝胰腺、体肉、腿肉、钳肉）总砷含量、水溶性砷形态、脂溶性总砷含量分布特征，分别采用电感耦合等离子体质谱法和高效液相色谱-电感耦合等离子体质谱联用技术分析中华绒螯蟹不同可食组织总砷、水溶性砷形态和脂溶性总砷含量。结果表明，在雌蟹中总砷均值含量呈现性腺＞肝胰腺＞体肉、腿肉＞钳肉的趋势，且有显著差异（P＜0.05）；在雄蟹中总砷均值含量呈现肝胰腺＞体肉、腿肉＞钳肉、性腺的趋势，且有显著差异（P＜0.05），雌蟹和雄蟹不同可食组织总砷含量随体质量的增大呈逐渐升高的趋势，8个省份中华绒鳌蟹成蟹性腺和肝胰腺中总砷含量处于相对稳定的水平。在肌肉组织中6种水溶性砷的百分比为83.3%~99.6%，性腺和肝胰腺组织中6种水溶性砷的百分比为18.8%~51.8%，肌肉组织与性腺、肝胰腺组织中水溶性砷百分比有显著差异（P＜0.05）。在性腺（雌）和肝胰腺（雌、雄）组织中脂溶性总砷的百分比范围为14.34%~72.59%，3个组织脂溶性总砷百分比均值无显著差异（P＞0.05），3个组织脂肪中总砷含量与相应组织总砷含量呈正相关性，与相应组织脂肪百分含量无正相关性。可见，中华绒鳌蟹不同可食组织总砷含量存在差异性，水溶性砷是肌肉组织中砷的主要形态，砷甜菜碱（AsB）是水溶性砷的主要成分，在性腺（雌）和肝胰腺组织中存在一定量的脂溶性砷，尚未见中华绒鳌蟹脂溶性砷种类，新陈代谢，潜在毒性以及来源的相关报道。

| Abstract: | In order to understand the distribution characteristics of total arsenic content, water-soluble arsenic species, and fat-soluble total arsenic content in different edible tissues (gonads, hepatopancreas, body meat, leg meat, clamp meat) of Eriocheir sinensis,inductively coupled plasma mass spectrometry and high performance liquid chromatography-inductively coupled plasma mass spectrometry were used to analyze the content of total arsenic, water-soluble arsenic species and fat-soluble total arsenic in different edible tissues of Eriocheir sinensis. The results showed:that the average content of total arsenic in female crabs showed a trend of gonadal>hepatopancreas>body and leg meat>clamp meat, and there was a significant difference; the average content of total arsenic in male crabs showed a trend of hepatopancreas>body, leg meat>clamp meat and gonads, and there were significant differences; the total arsenic content of different edible tissues of female and male crabs gradually increases with the increase of body weight, and the total arsenic content in the adult gonads and hepatopancreas of Eriocheir sinensis in 8 provinces is at a relatively stable level. the percentage of the 6 water-soluble arsenic in muscle tissue is 83.3%-99.6%, and the percentage of the 6 water-soluble arsenic in gonad and hepatopancreas tissue is 18.8%-51.8%, there was a significant difference in the percentage of water-soluble arsenic in muscle tissue and gonad, hepatopancreas tissue.The percentage of total fat-soluble arsenic in the gonadal (female) and hepatopancreas (female, male) tissues ranged from 14.3% to 72.6%, and there was no significant difference in the average percentage of total fat-soluble arsenic in the three tissues. The total arsenic content in the fat of the three tissues was positively correlated with the total arsenic content of the corresponding tissues, but there was no positive correlation with the percentage of the corresponding tissue fat. It can be seen that there are differences in total arsenic content in different edible tissues of Eriocheir sinensis, water-soluble arsenic is the main form of arsenic in muscle tissue, and arsenic betaine (AsB) is the main component of water-soluble arsenic, there is a certain amount of fat-soluble arsenic in the gonadal (female) and hepatopancreas tissues, there are no reports on the types, metabolism, potential toxicity and sources of fat-soluble arsenic in Eriocheir sinensis. |
