All ingestion of lead, regardless of the amount, is harmful to health. It is therefore paradoxical that the use of lead-based ammunition is still allowed.

In Norway, the average intake exceeds this threshold, and fatty fish is the main source. Nevertheless, the Norwegian authorities recommend that all...
