Dcr Einflufl von Erdiilkohlenwassersto~ft~n auf die Prinilrproduktion des Donsuplanktons S,io,imnry: Danube river water sdmples were saturated with mineral oil, and then the primary procliictioti (grcss) was dctcrtnined by means of the light-dark bot>tle niethod (oxygen) in sitii at d q ~t l i s of' 0 . 1 . . . 1.5 m in comparison with untreated samples. Samples were exposed for half a SCJltlT dn?-altrrnntely during the first and second half-days. Investigations carried out between .\law11 i;ud October for periods of 14 day3 showed a m e m proditcbion of 2.56 g * rn-'tl-l 0.. \r.hic*h ii i i h iwiutecl by 36'' ,, clue t'o 12.6 mg/l hyclrorarbons.
