Abstract
The paper is presenting the evolution in time of phosphorus, silicon
and total suspensions brought into the Black Sea by the Danube waters
in the period 1974-1977. The high level of agricultural and industrial
development and of urbanization lead to the growth of the phosphorus
quantities. Works on regulations of the river Danube and its affluents
have determined the diminution of silicon and total suspensions 
quantities.
