An investigation of heavy metal contamination of drinking water in the city of Trondheim, Norway

Conclusion

The analytical method described is very useful for quantitative determination of heavy metals in water samples.

The concentrations of Zn, Cd, Cu and Pb in domestic water in Trondheim are relatively small, and apparently constitute no reason for concern with regard to their public health implications; however one should be careful about using water from the heater in food preparation.

A few samples showed extraordinarily high values of lead due to local sources in pipes and heaters. The persons concerned have, of course, been informed.
