Abstract:
Sungai Como is located in Tasik Kenyir. Sungai Como received high total rainfall at north east monsoon and low at south west monsoon. Distributions of phosphorus in Sungai Como were assessed in October 2008 and December 2008. Ranges of total phosphorus for October and December were 0.09 - 2.36 μM. Basically, DOP was dominant phosphorus species in the water. The value for total phosphorus during non monsoon was higher than value during monsoon. This was because the concentration of phosphorus was diluted by total rainfall. Primary sources of phosphorus maybe come from soil runoff from land, microbial conversion of phosphate to DOP in the environment, reservoir phosphorus from jungle, cage cultures, recreation activity,
sedimentation mechanism and logging of land. The level of total phosphorus in Sungai Como was lower than logging of land. The studied of BOD level is still considered as safe. It concluded that there is no much organic waste present in the water of Sungai Como.
