In recent years, the naturally high background value region of Cd derived from the
weathering of carbonate has received wide attention. Due to the significant difference in soil …

Cadmium (Cd) concentration was investigated in parent rocks, surrounding soil of black
shales outcrop, stream water, stream sediments, paddy soil as well as rice plants. Leaching …

The fate of riverine sulfate ion (SO 4 2-) and its environmental effects in arid environment are
difficult to evaluate due to its complicated sources and strongly coupled behaviors with water …

Sulfide oxidation, coupled with carbonate weathering is thought to be a source of CO 2 over
geological timescales to offset CO 2 drawdown from silicate weathering. Its impact on the …

Dissolved inorganic carbon (DIC) is the most important carbon component in karst aquatic
system where fluid is highly transmissive, but has rarely been examined in the subtropical …

An analysis was performed of the hydrochemical characteristics of precipitation and river
water samples collected from the Liujiang River Basin from June 2014 to May 2015, SW …

To determine the mechanism underlying the effect of rainfall on the karst-related carbon
cycle while controlled by that of H 2 SO 4 and/or HNO 3, high-resolution monitoring was …

Magnesium isotopic composition (δ 26 Mg) could constrain sources and processes of
riverine Mg, thus providing new perspectives on budgeting the global Mg cycle. Carbonate …

Abstract The Gan River is a large tributary of the Yangtze River in Jiangxi Province, South-
central China. Hydrochemical data for this river were analyzed for the period 1958–2016. Ca …

A large amount of abandoned Pb–Zn tailings piled in the open air is one of the major
sources of heavy metal pollution in the surrounding environment because acid rains can …
