Study of nitrate waters of the southern basin of the Caspian Sea from Amirabad to Salman Shahr in (Mazandaran Province) in summer
This study performed in Caspian Sea in order to estimate nutrients nitrate factors (pH, temperature and salinity) from April to October 2008. Sampling was done in southeast Caspian Sea in five transects in 45 stations on surface water, 5 and 10 meter depths based on national standard. The mean concentration of nitrate was 5.37, 8.87 and 0.47 mg/l in first transect, it was 5.81, 9.98 and 0.76 mg/l in second transect, and 5.31, 11.76 and 0.71 mg/l in third transect, 5.40, 11.38 and 0.69 mg/l in fourth transect and 14.28, 14.89 and 2.09 mg/l in fifth transect. The concentration of nitrate was increasing from Salman Shahr to Amirabad. There was significant differences in nitrate concentration in transects (P<0.05), but the other parameters were not significantly different among surface, 5 and 10 m waters (P>0.05).
