Abstract:
This project was canied out to study the effects monsoon towards the distribution
of nitrogen in sediment around the Setiu Lagoon. This study was also conducted to
determine the concentration of total nitrogen content in the sediment. In this study, the
kjedahl method was used to obtain the total nitrogen content in the sediment. There were
14 sampling stations and three sampling trips was conducted which were during the premonsoon (September), inter-monsoon (October) and monsoon (December) season. The
second sampling (inter-monsoon) showed the highest of total nitrogen contents with
2.696 ± 0.046 mg/kg, compared to the first sampling (pre-monsoon) of 1.748 ± 0.043
mg/kg and the third sampling (monsoon) of 1. 738 ± 0.023 mg/kg. A statistical analysis
using a Two Ways ANOVA has been applied and found that there is a significant
different (P<0.05) among the stations and the sampling periods. From this study, it was
found that the total nitrogen contents in the sediment at Setiu Lagoon area were still in a
low level.
