Identification of agro-contaminants in surface and groundwater using stable isotope techniques
Agriculture intensification causes worldwide increase of rivers, lakes and groundwater aquifers pollution. Pollutants may originate from various sources related to different types of agriculture activities including cultivation, aquaculture, livestock and dairy farms and related food-processing industries, and partitioning their respective contribution to water bodies remains challenging. Degradation of water quality is associated with both macronutrients and micro-pollutants originating from the inefficient use of chemical and organic fertilizers, and transport and persistence of pesticides and antibiotics. Therefore, identification of spatial and seasonal variations of pollutant sources and loads at the catchment scale is critical for better understanding human and environmental impacts of agro-contaminants, and eventually improving land management practices to protect water quality.
This session is focused on the use of hydro(geo)chemical and stable isotope tracers in quantifying agro-contaminant sources and transport but other related studies are also welcome. We especially encourage submissions in the following topics:
• Application of multi-isotope tracer techniques to constrain sources
• Catchment-scale pollution budget and predictive modelling
• Nonpoint agriculture source pollution partitioning at different catchment scales
• Identifying sources of macronutrients and micropollutants: macronutrients, herbicides, fungicides and insecticides, antibiotics, rare earth elements
• Distinguishing agro-contaminants from other pollution sources at the catchment scale
• Agriculture land use and agro-contaminants diversification
