摘要: A study was undertaken to determine whether the isotopic ratios of C and N could be used uniquely identify municipal solid waste landfill leachate as a source contamination in Kaikorai Estuary, Dunedin, New Zealand. Leachate samples were taken from adjacent Green Island Landfill (GILF), surface water collected over an 8-month period stream estuary, upstream downstream landfill. Samples analysed for d 13 C–dissolved inorganic carbon (DIC), 15 N–NO3 , N–NH4 particulate organic matter (POM) N. Plant material along Stream POM found have distinct signature characterised by highly enriched C–DIC (as much 16.11F0.23x) 27.42F0.90x). Evidence signatures C–DIC, plant POM. Other potential sources present
