Preliminary Study on Evolution of Metals Contaminant Recorded in the Coastal Sediments of Semarang Waters

Suyarso and Tjutju Susana

The evolution of heavy metals contaminant of Cu, Zn and Hg at two main river mouths of Semarang
waters have been carried out on June 2009 through sediment cores, ages determination and supporting
with population and industry statistical data background. Heavy metals found at West Banjir Kanal
river mouth may be associated with natural origin on the contrary the increase of metals concentration
found at East Banjir Kanal river mouth is strongly correspond with population and industrial increases
since industrial decades. Objective of research is to collect heavy metals contaminant concentration
changed data over 30 years which have been recorded and saved in the layers of sediments in Semarang
coastal waters. The goal of research is to reconstruct the evolution of contaminant concentration
chronologically since industrialization decade. Method used in the research is data analysis through
sediment cores supported both population and industrial statistical data.
