1. General description of why an area is selected
Sampling locations for POPs monitoring were determined at five cities in Indonesia which is located in Jawa Island. Jawa Island particularly has serious problem because about 60 % of the total population live in an area of 132,000 km2 and where 80 % of the country's factory are located producing 77 % of the products manufactured in Indonesia. Those concentration of population and industry could be resulted heavy pollution in the river water of the main cities in Jawa Island. On the other hand those rivers have function to fulfill human activities. Therefore the major cities will be surveyed for monitoring POPs in river water are Jakarta, Bogor, Semarang and Surabaya. Jakarta and Bogor city are located in in Western part of Jawa Island, Semarang in the central part of Jawa Island and Surabaya is in the Eastern part of Jawa Island.
