Abstract
The presence and quantity of organic dissolved matter,
Cu, Pb, Zn, Mn as well as the load of some enteric bacteria
were studied on marine sediments. Samples from on area 
influenced both by the industrial waters and by the
hydrotechnical managements were analysed throughout 1984.
The rough data of organic dissolved matter (9.6-119 mg g-1),
those of Cu (2.88-69), Pb (5.93-44.38), Zn (21.6-170.6),
Mn (219.6-947.3 g g-1), bacterial density (0-384 germs g-1),
and the distribution of all these values demonstrated the
anthropogenic influence of the marine environment.
