Kaushal et al. 2017 (Applied Geochemistry) Human-accelerated weathering increases salinization, major ions, and alkalinization in fresh water across land use

•Base cations increased in drinking water over ∼50 years coinciding with urbanization. •DIC, cations, Si, SO42- and pH in streams increased with impervious surface...• 近50年来，饮用水中的碱阳离子（base cations）含量随城市化进程同步升高。 • 溪流中的溶解无机碳（DIC）、阳离子、硅（Si）、硫酸根离子（SO₄²⁻）及pH值随不透水面占比增加而上升……
