| Abstract |
Water samples were collected during the period 1970-1975 from several depths in the Baltic and Kattegat areas and analysed for non-polar hydrocarbons by an ifra-red technique. From pollution statistics one can conclude that the influx of oil to the Baltic ought to be of the order of some tens of thousands of tonnes per year. The analyses do not seem to confirm the presence of such quantities. There could be several reasons for this. For instance,the samples of about 2 litres may not be representative. Therefore the sampling programme should be combined with neuston net sampling of particles of oil or tar, to see if they appear in low or high quantities. Furthermore, field studies ought to be carried out on two other subjects; the quantity of oil present in marine sediments and the quantitative role of microbiological processes. |
