Abstract

A sampling expedition into the East Coast Peninsula Malaysia Exclusive Economic Zone (EEZ) was carried in June 2008. Marine surface sediment samples were collected and the activity concentrations of ²¹⁰Pb have been determined. Its distribution was plotted and the findings show that the activity concentrations decline from north to south. On the other hand, the activity concentrations are increasing from west to east right to the edge of the EEZ. The ²¹⁰Pb activity concentrations were found to be in the range of 18.3 – 123.1 Bq/kg.

 

Keywords: Activity, lead, sediment, distribution, trend, EEZ
