Distribution of nitrogen and phosphorus in Terengganu river estuary

Abstract

The distribution of nitrogen and phosphorus in Terengganu River Estuary were studied. The sampling stations were visited twice in order to fulfill the requirement as a part of my project. 13 sampling stations were established. The water samples for all the stations were taken at the surface, mid-depth and bottom water. The first sampling was carried out on 28 June 2002, Friday. The mean values of total ammonium at the riverine, estuarine and coastal water stations were 21.47, 5.41 and 0.90 J.LM respectively. While for total dissolved nitrogen the mean values were 53.35, 37.33 and 32.63 J.LM respectively. The mean values of orthophosphate were 0.18, 0.20 and 0.22 J.1M respectively, and for total dissolved phosphorus the mean values were 11.05, 7.83 and 3.39 J.1M respectively.
