Abstract

Sediment cores were obtained from Teluk Brunei, Sipitang, Teluk Kimanis, Kota Kinabalu and Kuala Penyu at the coastal water of Sabah and analyzed for 210Pb and 210Po to estimate the sedimentation rates. The calculated sedimentation rates of 210Pb and 210Po varied from 0.003 to 0.049 cm/y and 0.74 to 8.77 cm/y, respectively. The highest sedimentation rates were determined for 210Pb and 210Po at stations located at Sipitang (mean: 0.027 cm/y) and Teluk Kimanis (mean: 5.53 cm/y), respectively. The sedimentation rate estimated for 210Pb is not fully reliable because the activity of 226Ra was higher than that of 210Pb and bioturbation was active at the sampling stations.
