“…The decreasing trends of acid rain occurrence in China were also confirmed by a recent study. Chen et al [8] showed that the percentage of acid rain areas in the total surface area of China declined from more than 30% in the 1990s to 5.5% in 2018. Nevertheless, acid rain remains a challenging environmental problem in Sichuan province.…”

“…Following Europe and North America, China has the third largest acid rain region with acid rain mainly in the south of the Yangtze River ( Shu et al, 2019 ). Despite the dominance of sulfate in acid rain, the ratio of SO 4 2− /NO 3 − decreased by 81.9% in the period of 1998–2018, indicating the increase of NO 3 − ( Xuan et al, 2021 ). The annual average of wet nitrogen deposition increased from 11.11 to 13.87 kg ha −1 year −1 in China ( Jia et al, 2014 ; Zhu et al, 2015 ).…”

Karst caves are usually considered as natural laboratories to study pristine microbiomes in subsurface biosphere. However, effects of the increasingly detected nitrate in underground karst ecosystem due to the acid rain impact on microbiota and their functions in subsurface karst caves have remained largely unknown. In this study, samples of weathered rocks and sediments were collected from the Chang Cave, Hubei province and subjected to high-throughput sequencing of 16S rRNA genes. The results showed that nitrate significantly impacted bacterial compositions, interactions, and functions in different habitats. Bacterial communities clustered according to their habitats with distinguished indicator groups identified for each individual habitat. Nitrate shaped the overall bacterial communities across two habitats with a contribution of 27.2%, whereas the pH and TOC, respectively, structured bacterial communities in weathered rocks and sediments. Alpha and beta diversities of bacterial communities increased with nitrate concentration in both habitats, with nitrate directly affecting alpha diversity in sediments, but indirectly on weathered rocks by lowering pH. Nitrate impacted more on bacterial communities in weathered rocks at the genus level than in sediments because more genera significantly correlated with nitrate concentration in weathered rocks. Diverse keystone taxa involved in nitrogen cycling were identified in the co-occurrence networks such as nitrate reducers, ammonium-oxidizers, and N2-fixers. Tax4Fun2 analysis further confirmed the dominance of genes involved in nitrogen cycling. Genes of methane metabolism and carbon fixation were also dominant. The dominance of dissimilatory and assimilatory nitrate reduction in nitrogen cycling substantiated nitrate impact on bacterial functions. Our results for the first time revealed the impact of nitrate on subsurface karst ecosystem in terms of bacterial compositions, interactions, and functions, providing an important reference for further deciphering the disturbance of human activities on the subsurface biosphere.

“…The coal with the sulfur content of 3.5% used to be the major fuel for the traditional industrial Chongqing (Chang, 2022). By desulphurization of the fuel and using natural gas as the coal substitute, the frequency of acid rain declined significantly, from more than 90% in 1980s to 40% in 2018 (Xuan et al, 2021). However, SO 2 pollution is still one of the major environmental concerns in Chongqing.…”
