Abstract

In the present work INAA is used to determine as many elements as possible in peat samples from ombrotrophic bogs. Results for depth distribution profiles of some elements of particular interest are presented for selected bogs from areas with highly different input from long-range atmospheric transport of pollutants. In addition to information on air pollution, the data provide knowledge about contribution from natural processes to the airborne supply of some elements, such as in the case of selenium.
