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

The chemical record in Loch Lomond sediments deposited since the end of the last Ice Age provides evidence of the Flandrian marine transgression some 5500-7000 C-14 years B.P., sedimentation rates and the influence of man's local activities, environmental pollution and its sources since the onset of the Industrial Revolution, and of elemental mobility linked with the reduction-diffusion-oxidation cycle of early sedimentary diagenesis. Information derived from vertical profiles of halogen elements bromine and iodine, radionuclides C-14 and Pb-210, heavy metals lead, zinc, and cadmium, stable lead isotopes Pb-206 and Pb-207, and redox-sensitive elements manganese, iron and arsenic is reviewed and assessed.
