Nutrient Salts and Chlorophyll-a During Short Term Scale in the Eastern Harbor, Alexandria (Egypt)

0.47-10.40(2.23) for NO3-N, 0.12-1.48 (4.06) for NO2 -N, 0.35-6.19(2.23) for NH4-N, 0.04-8.58(1.03) for PO4-P, and 0.37-11.90(3.45) for SiO4. The values of OOM ranged from 0.42 to 17.50 mg O2/l with an average value of 4.73mg/L. The distribution of both NO3-N and NH4-N were referred to that the rate of nitrification and denitrification is mostly similar. The N/P ratio (4.76) in the present study is lower than Redfield\u27s ratio , indicated that nitrogen is the limiting factor. The levels of nutriens and chlorophyll-a indicated that the harbor is in eutrophic condition
