Retention Ponds Pollution Level Monitoring in Palembang City for Achieving a Sustainable Urban Environmental Health and Ecosystem Service

Abstract

Retention pond (RP) is part of green open space in the city. One of its functions is to provide ecosystem service to urban lives, thus its health should be protected. Measuring its pollution level is an important step for designing action plans for its protection and restoration. This study showed, based on Palmer Pollution Index scoring, both retention ponds located in PSCC and beside Siti Khodijah hospital showed possible high organic pollution levels (scores are 17 and 18) respectively, these are signals for priority treatment actions. The other seven RPs are at a medium level (the scores are 11 to 13), and the last four showed low organic level (the scores are 0-3). A further observation found that the PSSC retention pond was constantly dominated by Planktotrhix agardhii., a cyanobacter under concerned due to its potential to release cyanotoxin. A preliminary study was done in this study showed it had an effect to Cyprinus carpio L., gill and pathologic effects in the gill's lamella.
