ABSTRACT
Ihe dYllamics ofnutrient salts befHieell bottom sediments and the adjacent
Imter ill the Noz!la Hydrodl’Ome, Alexalldria (Egypt) was estimated in the
laboratOly. Ihe sediments were hauled.from an area c011taiilillg silty dej}()sits
(St. 1) and another \vl1ich is characterized by its more coarse texture (St. 11).
Ihe bottles C()”taillillg the sediments (6 gm dly weightibottle) alld water
samples were incubated in the dark at an average temperature of22°C and
chemical analysis of the supernatant water were petformed at the beginning
