Abstract

Activity levels of 210Po and 210Pb were determined in the edible tissue of seabass (Lates calcarifer) from 23 cages located in the west, south and east coasts of Peninsular Malaysia. The concentration levels of 210Po and 210Pb in fish varied from 5.10 ± 0.36 Bq/kg to 15.53 ± 5.40 Bq/kg dry weight and 7.09 ± 0.54 Bq/kg to 21.72 ± 2.64 Bq/kg dry weight, respectively. The highest concentrations of 210Po and 210Pb were found at Stations S3 and S23 due to rapid development at the upper stream. In addition, the ratio between 210Po and 210Pb shows a distinction between stations of each sampling location. The 210Po/210Pb activity ratio at the Tebrau Strait was higher than the unity value (1.04) compared to the west and east coasts of Peninsular Malaysia. Most of the samples contain slightly lower 210Po/210Pb activity ratios which are related to the high input of lead from watersheds in neighboring areas.
