The present study determined concentrations of estrogenic bisphenol A (BPA), nonylphenol, octylphenol (4-tert-octylphenol), butylphenol (4-tert-butylphenol), and progestogenic norethindrone by liquid chromatography–tandem mass spectrometry in bile extracts from field fish from the Xin'an River and market fish in Shanghai, China. Compared with the field fish, endocrine disrupting chemical (EDC) concentrations in market fish bile were at relatively high levels with high detectable rates. The average concentrations of BPA, nonylphenol, 4-tert-octylphenol, 4-tert-butylphenol, and norethindrone in field fish bile were 30.1 µg/L, 203 µg/L, 4.69 µg/L, 7.84 µg/L, and 0.514 µg/L, respectively; in market fish bile they were 240 µg/L, 528 µg/L, 76.5 µg/L, 12.8 µg/L, and 5.26 µg/L, respectively; and in the surface water of Xin'an River they were 38.8 ng/L, 7.91 ng/L, 1.98 ng/L, 2.66 ng/L, and 0.116 ng/L, respectively. The average of total estrogenic activity of river water was 3.32 ng/L estradiol equivalents. High bioconcentration factors (BCFs) were discovered for all 5 EDCs (≧998-fold) in field fish bile. Furthermore, the authors analyzed the BCF value of BPA in fish bile after 30-d exposure to environmentally relevant concentrations of BPA in the laboratory, and the analysis revealed that BCF in fish bile (BCFFish bile) changed in an inverse concentration–dependent manner based on the log10-transformed BPA concentration in water. Strikingly, the data from the field study were well fitted within this trend. The data together suggested that analysis of fish bile extracts could be an efficient method for assessing waterborne EDCs exposure for aquatic biota. Environ Toxicol Chem2015;9999:1–9.
古代的魚膽 和現在的魚膽有很大不同。現在的魚膽你都不知道有多少化學藥品和其它毒物。。

同意。孩子吃了一年半魚膽都沒事。不排除那條大草魚是在工業汙染的水域捕撈的,是屬於工業汙染中毒而並非魚膽。

比魚膽毒幾萬倍的高濃度水銀都可以注射在初生嬰兒體內,連續注射五六年,西醫都認定是安全的無害的,更何況現在是9歲的孩子?

好像魚膽有毒吧,記得以前看過一篇文章,一個媽媽將魚膽給女兒吃去火,結果小女孩死了

話不能這樣說,很多兒童注射了疫苗後就死亡,西醫不也說疫苗是安全的嗎?你說的這個報道可以歸類為Anecdotal
