This poses a risk of adverse health effects such as methaemoglobinaemia in infants and gastric and oesophageal cancers for both urban and rural populations.

Combining the datasets with local schemes of fertilization and irrigation, we finally develop a high-resolution and real-time N inputs and irrigation datasets from targeted cities or regions.<\/li>\n<li style=\"text-align: justify\">Both land surface model (ORCHIDEE-CROP, Wang et al., 2017) and flux upscaling approach (Gao et al., 2016, Hou et al., 2017) are applied for the estimates that are constrained by multi-source observations of N leaching fluxes. Regional N leaching at different soils and the associated N flow in aquifer groundwater will be quantified under different agricultural management and climate change.<\/li>\n<li style=\"text-align: justify\">Based on probabilistic effect-response functions, we will assess negative effects of N applied in urban and rural agricultural soils on human and livestock health, and implement N inputs and irrigation datasets from different scenarios of agriculture management and climate change to models, thereby quantifying how they affect the N-related concentrations in the urban groundwater.<\/li>\n<\/ul>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Agricultural soils account for considerable nitrogen leaching to groundwater.
