However, most researches on acid rain have mainly focused on pot experiments, while in-situ research on maize is still rare. Therefore, this study conducted two-season field experiments to investigate the effects of three simulated acid rain treatments with three pH levels (2.0, 3.5 and 4.5) on maize growth compared with control (pH_6.0). The results showed that simulated acid rain inhibited the growth and yield of maize. At pH_2.5, the plant height and stem diameter of maize decreased by 8.55% and 11.49%, and the leaves were irregularly damaged. Under pH_2.5, actual photosynthetic efficiency decreased by 23.55%, the growth and development of plants were directly affected. As a result, maize yield decreased by 17.64% at pH_2.5. Moreover, at pH_4.5, fructose content in the kernels decreased by 16.95%, while the glucose content increased significantly by 79.22%. At pH_4.5, the activity of superoxide dismutase (SOD) increased by 37.63%. In summary, acid rain affected the physiological characteristics of maize, resulting in a decline in grain quality and yield. And maize could respond to acid rain stress by adjusting carbohydrate metabolism and enhancing antioxidant mechanisms. These findings depict the response of maize to acid rain and provide a reference for alleviating the impact on maize growth through sustainable agricultural practices in an acid rain environment.</div></div>","PeriodicalId":8604,"journal":{"name":"Atmospheric Pollution Research","volume":"16 2","pages":"Article 102382"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143131627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, the quantity of CO₂ emitted by land is mainly assessed in terms of concurrent soil respiration. It is unclear whether there are any background terrestrial sources of CO₂. According to the closed system model, earth-air (the air in the vadose zone) and atmospheric air are widely exchanged at the land's surface due to the barometric pumping effect. In order to calculate the amount of CO₂ released from the extremely arid region, an inventive device was utilized to monitor the amount of earth-air and CO₂ flowing. The findings demonstrate that the concentration of CO₂ in the earth-air rises when atmospheric pressure falls and it is proportionate to the earth-air flow. The CO₂ emitted from the land is positively correlated with temperature, amplitude of atmospheric fluctuations, and thickness and porosity of the vadose zone. CO₂ continuously migrates upwards driven by barometric pumping. Emission of CO₂ from land is widespread due to earth-air exchange. The total CO₂ emission varies with the season, exhibiting a ‘γ-shaped’ profile over the course of a year. On a daily timescale, the CO₂ flow varies in a bimodal manner. The average yearly CO₂ concentration in the pipe outflowing earth-air is 789.2 ppm; that of the inflowing air is 594.5 ppm. This study provides a method for monitoring terrestrial CO₂ release.
