Abstract

Surface water and sediment samples from Mt. Diwalwal and Naboc River were analyzed for total mercury by mercury vapor generation AAS. An exceedance in the total mercury concentrations from the DENR standards for water (2.00 ppb) and sediments (0.10 µg/g) in practically all the sampling sites were observed for the two sampling periods: July 25 to 30 and November 13 to 20, 1997. The highest mercury level found in surface water is 3,124.40 ppb at the Depot Creek-Naboc River confluence in Mt Diwalwal and 1,979.80 ppb at the Naboc-Agusan River confluence at the lowland. Gold processing ballmill plant was found highest for sediment at 926.40 µg/g.
