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.
