How to check mercury content in fish?

Mercury is detected by the cold vapour atomic absorption spectrometry technique using an automatic mercury analyzer developed at the National Institute for Minamata Disease (NIMD).

What is the acceptable level of mercury in fish?

Studies report mercury concentrations in fish muscle tissue ranging from 0.01 to 0.67 μg/g, with carnivorous species like Plagioscion squamosissimus showing higher levels due to biomagnification, sometimes exceeding the World Health Organization's safety threshold of 0.5 μg/g.

Why is tuna high in mercury but not salmon?

Try canned salmon. It has lower Mercury content. Mercury content in fish is something that builds over time. So, very simply, the older and larger the fish is, the more mercury it will have in it. Salmon are much smaller and have much shorter life cycles than Tuna. So they have less mercury.

Which fish have the most mercury?
