ENVIRONMENTAL-CHANGE AND THE CHEMICAL RECORD IN LOCH-LOMOND SEDIMENTS

The chemical record in Loch Lomond sediments deposited since the end o f the last Ice Age provides evidence of the Flandrian marine transgres sion some 5500-7000 C-14 years B.P., sedimentation rates and the influ ence of man's local activities, environmental pollution and its source s since the onset of the Industrial Revolution, and of elemental mobil ity linked with the reduction-diffusion-oxidation cycle of early sedim entary diagenesis. Information derived from vertical profiles of halog en elements bromine and iodine, radionuclides C-14 and Pb-210, heavy m etals lead, zinc, and cadmium, stable lead isotopes Pb-206 and Pb-207, and redox-sensitive elements manganese, iron and arsenic is reviewed and assessed.
