Short summary

The southeastern coastal region is the top acid-rain-impacted area in China. It is worth evaluating the acid deposition impacts on chemical weathering and CO₂ consumption there. River water geochemistry evidenced an overestimation of CO₂ sequestration if H₂SO₄/HNO₃ involvement was ignored, which accounted for 33.6 % of the total flux by silicate weathering in this area. This study quantitatively highlights the anthropogenic acid effects on chemical weathering and associated CO₂ consumption.
