Abstract

During sprint cruise (2013), numerous measurements of nutrient levels were conducted across the Algiers region (Algiers Bay, Bou-Ismail Bay and Zemmouri Bay) in order to assess the state of pollution by nutrient salts. Twelve stations were sampled along the Algiers coast using a NISKIN bottle. The nutrients (e.g., nitrates NO3-, nitrites NO2-, ammonium NH4+, orthophosphate PO43- and silicates SiO2) were analyzed in the laboratory. the results show fluctuations with measured concentrations of nitrate (1.81-3.39 µmol/L), of nitrite (0.18-0.28 µmol/L), of ammonium (1.23-33.93 µmol/L), of orthophosphate (0.89-5.08 µmol/L), and of silicate (2.55-7.64 µmol/L). The non-significant correlation between nitrate and phosphate data (R² = 0.0366) allows us to estimate an N/P ratio of -0.071.
