Conclusion: Stable Isotope Tracers Are Useful for the Identification of Pollutants in Agro-ecosystems

AbstractPollutant management in agro-ecosystems is a complex challenge that requires two key questions to be answered: (i) how to improve identification and quantification of pollutant sources, transport pathways and fate on the catchment scale? and (ii) how to prioritise and combine soil and water management practices to minimise the use and impact of agro-pollutants? An integrative book such as this one, focusing on the stable H, C, N, O and S isotope compositions of a variety of agro-pollutants, may help to address the first question and enable increasingly precise and robust evaluation of pollution in agro-ecosystems.
