Trophic state of the northern Adriatic

The annual mean trophic index and efficiency coefficient were used to address the trophic state of the northern Adriatic in the last forty years. Differences in the efficiency of nutrients use between the western (more eutrophied) and eastern (more oligotrophic) part were identified at the beginning of the investigated period. Later, after the ban of polyphosphates in detergents (mid-eighties) the NA ecosystem showed similar patterns in the whole area.
