摘要

Water quality in rural areas is sensitive to a variety of non-point pollution sources fromagriculture, livestock-farming, forest, and residential areas due to multi-purpose land use.This study was conducted to characterize stable isotope and elemental compositions ofpotential pollution sources including formula feed, livestock manure, nutrient inputs (syntheticfertilizer and compost), agricultural soils (paddy, upland, and orchard), plant residues (ricestraw and tree litter), and water samples (paddy drainage water, forest runoff water, andsewage waste water) to explore potential use of isotopic and elemental compositions inestimating water pollution sources. All the samples were collected from the Pungyoungjeongriver watershed located in Jangseong of Chonnam Province, Korea. The samples wereanalyzed for concentrations of C and N and isotope ratio of C (13C) and N (15N) and metal(Ca, Mg, K, Na, Zn, Cu, and Al) concentrations. Each pollution sources have distinct isotopic(13C and 15N) and elemental composition (Cu and Zn). For example, manure and its composthad higher isotopic values (13C and 15N) and metal (Cu and Zn) concentration; whereassynthetic fertilizer had lower 15N. Upland and orchard soils had a higher 13C and 15N dueto continuous application of 13C- and 15N-enriched livestock manure. Sewage waste waterexhibited a higher Na/Ca ratio refl ecting excessive salt use in diet. Therefore, our studysuggests that the potential water pollution sources have contrasting isotopic and elementalcompositions and thus it may be possible to use such characteristics in identifying waterpollution sources.
