Preliminary study on phytoliths identification in two major riverbanks of Selangor (Gombak and Klang riverbanks)
Phytoliths are plant fossils found within the plant cells of embryophytes and it can be deposited into the uppermost horizon of the soil when embryophytes die and decay. This will cause the phytoltihs is released from its organic matrix and chemisorbed into the soil particles. This study aimed to...

| Summary: | Phytoliths are plant fossils found within the plant cells of embryophytes and it can be deposited into the uppermost horizon
of the soil when embryophytes die and decay. This will cause the phytoltihs is released from its organic matrix and chemisorbed
into the soil particles. This study aimed to determine the presence and morphology of phytoliths found in two major riverbanks
of Selangor (Gombak and Klang riverbanks). Composite soil samples were collected from the top two cm of the soil of
Gombak and Klang riverbanks with each composite consists of five subsamples. The distance between each subsample is
two m apart. The composite soil samples were subjected to extraction process before phytoliths isolation which involved
deflocculation using 5% of sodium hexametaphosphate, decarbonation using 10% hydrochloric acid, organic material removal
using 65% nitric acid and potassium chlorate, clay removal via centrifuge sedimentation and, organic matter and humic colloids
removal using 10% potassium hydroxide. Heavy liquid zinc bromide/hydrochloric acid was used to isolate phytoliths. The
presence and morphology of phytoliths between the two riverbanks were identified and counted using comparison microscope.
The results were compared between the two riverbanks to determine if discrimination of soil in different site is possible. |
