This study provides a comprehensive analysis of the occurrence of androgens, glucocorticoids and progestogens in typical freshwater aquaculture farms in comparison with marine aquaculture farms. The results showed that more steroids were detected in the marine aquaculture farms. For all aquatic products, the total concentrations of steroids in fish muscle were 22-2000ng/g, which were much higher than those detected in crabs, shrimps or mollusks (0.5-8.1ng/g). Based on the hazard index of the selected steroids, most water samples were in the low or medium risks. Some banned steroids were identified in the freshwater shrimps and all marine products, indicating that there may be certain health risks by the consumption of these aquatic products in the studied aquaculture farms. Furthermore, the total contributions of steroids in China were estimated to be 2300kg/y and 1200kg/y from freshwater fish culture and shrimp-crab culture, respectively.
本研究对典型淡水养殖场和海水养殖场中的雄激素、糖皮质激素和孕激素的产生进行了全面分析。结果表明，海洋养殖场中检测到的类固醇更多。对于所有水产品，鱼类肌肉中类固醇的总浓度为 22-2000ng/g，明显高于蟹、虾或贝类（0.5-8.1ng/g）中的浓度。基于所选类固醇的危害指数，大多数水样处于低或中风险。在淡水虾和所有海洋产品中都发现了一些禁用的类固醇，这表明在研究的养殖场中食用这些水产品可能存在一定的健康风险。此外，估计中国来自淡水鱼类养殖和虾蟹养殖的类固醇总量分别为 2300kg/y 和 1200kg/y。
