Eutrophication has become one of the most serious problems facing water environments. Exploring relationship between anthropogenic activities and river trophic status provides effective information for environmental improvement restoration, whilst remains poorly understood. Herein, 5225 samples were collected monthly from 12 tributaries covered upstream in Three Gorges Reservoir, China during 2014–2020. Quantitative based on land-use covers used to establish correlations with tributary...
Nitrate pollution in oxygenated karst aquifers is common due to nitrification and anthropogenic inputs. However, the shift of nitrogen sources influenced by enhanced rural tourism activities land use changes are not well understood. In this study, hydrochemistry dual nitrate isotopes water samples from a basin Chongqing, southwestern China were employed investigate fate its decadal change during periods 2007-2008 2017-2019. The results showed that δ15N-NO3 δ18O-NO3 values at groundwater...
The objectives of this study were to reveal the sources nitrate and ratio karst in an agricultural basin based on a 15N 18O isotope technique quantitative calculation IsoSource model. From May October 2017, six sampling points Qingmuguan river basin, Chongqing, monitored every 24 d. Results showed that there was great risk pollution underground system, because most NO3--N concentrations exceeded threshold. Spatially, increased from upstream downstream. Temporally, Fishpond Yankou Ponor...
