Distribution of nitrogeneous compounds and chlorophyl-A at Nerus river basin, Terengganu.

Abstract

The study of nitrogenous nutrients and chlorophyll-a has been carried out at nine sampling stations along the Nerus River. The nitrite, nitrate, total nitrogenous particulate and total dissolved nitrogen has been determine using diazonium method whereas, pigment extraction method based on the APHA Standard Methods was use to analyze chlorophyll-a. In addition, the in situ measurements were also conducted during sampling for the physical parameters determination such as temperature, salinity, dissolved oxygen and pH by using YSI multi parameter data logger.
