| Resumo |
Detailed geochemical investigations of bottom sediments in the Pechora Bay were carried out under a monitoring regime. The regional geochemical background is characterized. Organic matter of sediments is found to be clastic, formed under the influence of Pechora River run-off, and determined by genetic and lithofacial factors. An application of geochemical methodology is suggested for estimating hydrocarbon contamination of bottom sediments. As an example consequences of the accidental Usinsky oil spill are studied. They are based on analysis of composition of molecular markers. It is shown that increasing technogenic impact on Pechora Bay sediments is fixed only at molecular level and is not disastrous. |
