In this work, we monitored the seasonal variation of carbonyl compounds in the coastal city of Qingdao, located in the north of China's coastline and the south of Jiaodong Peninsula, with the vast hinterland in the west. The mean total concentration of the 15 carbonyls varied significantly between seasons, with the highest observed in autumn (10.2 ± 6.2 ppbv), followed by spring (9.0 ± 3.0 ppbv), winter (6.4 ± 4.0 ppbv) and summer (3.4 ± 1.4 ppbv). Using bivariate analysis, the agricultural emissions from inland areas were responsible for the high levels of carbonyls in the autumn. In summer, clean and humid sea winds helped reduce the concentration of carbonyls, but they also brought air masses from vegetation, and marine organisms, which contributed to high levels of carbonyls in the spring of coastal areas. The observation-based chemistry box model found that the formation of formaldehyde and acetaldehyde was primarily controlled by the RO + O₂ reaction, and alkenes oxidation was the main contributing factor. Based on the OH radical loss rate (<em>L</em>_OH) and ozone formation potential (OFP) calculation, we found that autumn and spring seasons have significantly higher values of <em>L</em>_OH and OFP than winter and summer due to the presence of high concentrations of carbonyl compounds. Therefore, it is believed that these carbonyl compounds primarily originate from agricultural activities, and marine air influences the atmospheric chemistry of the coastal areas.</div></div>","PeriodicalId":15788,"journal":{"name":"Journal of Environmental Sciences-china","volume":"154 ","pages":"Pages 859-870"},"PeriodicalIF":5.9,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

HBQs and aromatic AAs were analyzed using solid phase extraction with high performance liquid chromatography–tandem mass spectrometry methods. The only HBQs detected in treated water were 2,6-dichloro-1,4-benzoquinone (DCBQ) and hydroxy‑DCBQ (OH-DCBQ). The concentration of DCBQ was 3–4 times higher during spring runoff events than during non-spring-runoff periods, suggesting the impact of spring runoff on the formation of DCBQ. The DCBQ concentrations in finished water positively correlated with the color, dissolved organic carbon, total organic nitrogen, and specific ultraviolet absorbance WQPs of source water in 2021 and 2022. The temporal trend of the total aromatic AAs determined in source water was strongly and positively correlated to DCBQ in finished water. Finally, there was a significant positive correlation between the concentration of DCBQ determined immediately following the addition of chlorine and the presence of its transformation product, OH-DCBQ, in finished water.

Herein, MXenes use as a support and in situ loading S-nZVI on it to prepare a new material (S-nZVI/Ti₃C₂T_x), and applied it to U(VI) removal in water treatment. The microscopic characterization proves that S-nZVI on Ti₃C₂T_x has good dispersion and effectively alleviates agglomeration. Batch experiments shown that S-nZVI/Ti₃C₂T_x has a very good effect on U(VI) removal, and the maximum adsorption capacity reaches 674.4 mg/g under the aerobic condition at pH=6.0. The pseudo-second-order kinetic model and the Langmuir isotherm model were found to be more appropriate for describing the adsorption behavior. This indicates that the removal process is a single molecular layer chemisorption. Moreover, the S-nZVI/Ti₃C₂T_x maintained a removal efficiency of over 85 % for U(VI) even after being reused five times, demonstrating its excellent reusability.
