| Zusammenfassung |
| Anthropogenic inputs influence the quality and quantity of organic matter, which is important
for recycling of nutrients and chemical elements. Stable isotope techniques are useful for
distinguishing the origin of organic matter by using the characteristics that are distinctive
between sources. Artificial Lake Shihwa, especially the Shingil creek is typically under the
strong anthropogenic pressure with continuous continental inputs from various sources.
Hence in this study, the characteristics and sources of organic matter in water and surface
sediment of the Shingil creeks in the rural, urban, and industrial areas were evaluated by
using carbon, nitrogen and oxygen isotope ratios, by analyzing samples collected during the
rainy season and dry season. Among the input sources, the organic matter derived from
industrial regions showed distinct nitrogen isotope values compared to other sites. Further
studies including other techniques such as hydrogen isotope will provide an insight into the
development of a strategy for effective water quality management in Lake Shihwa |
