Nutrient (nitrogen and phosphorus) discharges from Kerteh River at selected tide, Terengganu

Abstract

The study was carried out to determine nutrient distribution in the estuarine and riverine water ofKerteh, Kemaman. Two samplings were conducted on the 27th April 2010 and on the 28th October 2010. Ten sampling stations were covered during the first sampling at estuarine and riverine water while also ten sampling stations during the second sampling. The mean nitrite concentrations during the first sampling were 0.04 m/L while during the second sampling were 0.03 mg/L. Mean nitrate concentrations during the first sampling were 0.64 mg/L while during the second sampling were 0.58 mg/L. Mean ammonia concentrations during the first sampling were 0.045 mg/L and while during the second sampling were 0.014 mg/L. Mean orthophosphate concentrations during the first sampling were 0.007 mg/L while during the second sampling were 0.009 mg/L. Mean of total nitrogen concentrations during the first sampling were 10.5 mg/L while during the second sampling were 10.45 mg?L. Mean total phosphorus concentrations during the first sampling were 5 .46 mg/L while during the second sampling were 5.06 mg/L.
