Abstract  

The normal levels of arsenic in human tissue are reported together with the arsenic concentrations found in the investigation of a large number of industrial exposure incidents. These results are useful for establishing that industrial exposure has taken place and for confirming arsenic poisoning but they cannot be used realistically to predict that any person or group will suffer a visible deterioration in health because no correlation between arsenic contamination and symptoms can be made. Industrial workers who are affected by arsenic exposure are often no more exposed than their co-workers.

Abstract  

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.
