TL;DR: In this paper, the chemical and isotopic compositions of the dissolved load of the rivers of the Changjiang Basin, one of the largest riverine systems in the world, were analyzed.

TL;DR: In order to assess the sources and conversion of nitrate in the groundwater of Guiyang, Wang et al. as mentioned in this paper analyzed the major ions, δ15N-NH4+, δ 15N-NO3-, and δ18O-No3- in surface and groundwater samples collected during both summer and winter seasons.

TL;DR: In this article, the authors used carbon isotopic evidence and water chemistry of springs and rivers from the Beipanjiang River basin (Guizhou Province, Southwest China) to demonstrate that sulfuric acid is also an important agent of rock weathering.

TL;DR: The sources and variability in nitrate of the Changjiang River are assessed for the first time using dual isotopic approach and there was a strong positive relationship between delta(15)N-NO(3)(-) and delta(18)O-NO (3)(-), which indicated that denitrification added to the enrichment of heavy isotopes of nitrate.

TL;DR: Overall, the present study quantitatively evaluates the spatio-temporal variations in nitrate sources in a subtropical watershed, and the high-frequency monitoring gives a better estimate of nitrate exports and proportional contributions of nitrates sources.
