A survey of the mercury content of the diet in the Glasgow area is described. A higher intake of mercury (60 μg/day/person)
than that expected is found. However, there does not appear to be any concentration of mercury by man. None of the foodstuffs
show any exceptional mercury content. Fish levels are similar to other foods and a preliminary sample of shellfish from the
Clyde estuary, a contaminated area, shown no sign of their having concentrated mercury to any significant degree.
