Monitoring of Persistent
Organic Pollutants (POPs) in the coastal hydrosphere of Indonesia was carried
out to investigate environmental contamination by some POP compounds. Sampling
location was determined in four cities in Java Island including Jakarta, Bogor,
Semarang and Surabaya. Water,
sediment and river bank soil samples were collected in dry season of July
2004, and rainy season in January 2005.
Some of POP compounds (DDT, Endrin, Dieldrin, Aldrin, HCB, Heptachlor,
Chlordane, Mirex) were analyzed as target compounds.
Additionally, some of organochlorine insecticides, including a group of Hexachlorocyclohexane
(a-HCH, b-HCH, d-HCH, g-HCH) and Metoxichlor were
also analyzed by using GCMS QP2010. The monitoring result indicated that some
of POP compounds especially DDT and its derivates were still detected in water
samples in very low concentration. Other POP compounds (Heptachlor, Dieldrin)
were also detected in river water at a few sampling sites. In sediment samples, DDT and its derivates
were also detected in higher concentration than in water samples.
Dieldrin, Endrin and Dieldrin were also appeared in sediment samples.
As in sediment samples, DDT and its derivates were still as major compound
detected in river bank soil with higher concentration than in river water.
The existent of some POP compounds in the environment proved that the
residue of those compounds was still remain in the
environment for along time.
