- Abstract
- Sources of organic matter in a polluted coastal embayment (Lake Sihwa) indicated that delta C-13 and delta N-15 of suspended particulate matter (SPM) and sediments could be distinguished by land-use type and surrounding activities. Specifically, low delta N-15 occurred in inland creeks near industrial complex, where severe contamination by persistent toxic substances (PTSs) is evidenced. To identify the sources of N-15-depleted organic matter and PTSs, the SPM and/or sediments were collected along similar to 8 km of the Singil Creek and in stormwater drainage pipes that carried pollutants to the creeks from upland areas. Results indicated that stormwater originating in industrial areas was the main source of low delta N-15 and elevated PTSs, which appeared to flow into stormwater drains with rainwater and eventually into the creeks at stormwater outfalls. To improve the water quality of inland creeks, it will be necessary to reduce the amount of untreated stormwater entering stormwater drainage system from industrial complex.
