    Abstract

    Pb-210 dating has been tested in an ombrotrophic peat bog in S-W Denmark. The favourable conditions in ombrotrophic systems facilitate the evaluation of a continuous time/depth scale, using a combination of Pb-210 and C-I 4 datings. The age determination has improved the contemporary prospection of the processes in the bog and of the deposition of heavy metals, reflected in the peat. A detailed description of lead deposition is given. - Since A.O. 1300 the lead deposition in Draved Mose has increased from 0.5 mg Pb m-2y-1 to about 50 mg Pb m-2y-1 (A.D. 1970- 1978). It has been made render that approximately 70% of the recent lead deposition derive from alkyl-lead petrol whereas the rest originate from lead manufacturing industries and other sources.
