The average person in Hong Kong consumes fish or shellfish four or more times a week averaging about 60 Kg of fish per year.
Even though the mean mercury level in store-bought Hong Kong fish was only 0.12 mg/kg, corroborating evidence is presented from numerous studies to support the view that mercury bioaccumulates.
By the time a typical Hong Kong male reaches 30 years pf age he will have accumulated approximately 4 mg/kg mercury in his hair.
By age 60, his hair mercury levels will have increased to about 7.5 mg/kg.
Hair is a useful indicator of mercury exposure.
In the U.S. over a million hair samples have been examined for mercury (mean, 1.5 mg/kg).
The mean hair mercury concentration for over 200 Hong Kong residents was 3.3 mg/kg which is more than double the U. S. mean (well over one standard deviation above the U. S. mean).
Two lines of evidence support the hypothesis that fish is the major source of methyl mercury in the diet of Hong Kong residents. 1. Individuals consuming 4 or more meals of fish per week had a hair mercury of 4.07 mg/kg dry weight of hair while those consuming fish less frequently had significantly lower levels (2.56 mg/kg). 2. Hong Kong residents that consume no fish had only 0.38 mg/kg hair mercury.
The World Health Organization has adopted the U. S. EPA levels for mercury and recommends that food with mercury concentrations of 0.5 mg/kg or more should not be sold for human consumption. (...)
