Abstract

The present investigation was performed in order to monitor water quality and to establish the proper background for environmental studies in Bushehr province waters (Coastal Waters ofBushehr to Delvar). Sampling was occurred seasonally at depths of less than 10 m by using a Rottner sampler at 10 stations including Jophreh, Jalali, Dastak, Saretol, Helileh, Bandargah, Niroogah, Bushehr, Piazy and Delvar from the summer 2015 to the spring 2016. Amount of ammonia, nitrate, nitrite, Orthophosphate, silicate, total suspended matter and chlorophyll a were measured and then analyzed by one way ANOVA and Tukey tests. The average amounts of above parameters were recorded between 0.04-0.123 mg/l, 0.003-0.0944 mg/l, 0.0013-0.0212 mg/l, 0.010-1.812 mg/l, 0.147-1.257 mg/l, 21.93-44.67 mg/l and 0.37-2.77 mg/m3 , respectively. Other than the total amount of autumn and spring total suspended matter and summer Orthophosphate in a few stations, the concentration of other factors were in natural fluctuations during sampling periods.
