Is There Mercury In Egg Yolks? eggs obtained from the Chicagua River contained mercury, with embryos exhibiting the highest levels (mean = 0.079 μg/g, range = 0.013-0.389), egg yolks having intermediate levels (mean = 0.031 μg/g, range = 0.011-0.145), and eggshells the lowest levels of THg (mean = 0.010 μg/g, range = 0.001-0.023; Kruskal-Wallis, df
How Much Does A Mercury Test Cost For Fish? Larger fish tend to eat many smaller fish, which contain small amounts of mercury. As it’s not easily excreted from their bodies, levels accumulate over time. This process is known as bioaccumulation ( 6 ). Mercury levels in fish are measured as parts per million (ppm).
How Much Mercury In Grouper Fish? All species of grouper have a mean mercury ppm (parts per mille, or thousand) of 0.448, which is considered moderate. For comparison, low-mercury fish like fresh salmon average 0.022 ppm, and cod average 0.111 ppm (source: FDA). While gag grouper – one of the better grouper choices – has
