The marine environment is not impacted by CO2 storage itself but by the unlikely event of leakage. Thus, it is referred to as potential environmental impact assessment (PEIA). We conducted an ocean simulation for Hidaka Bay off Hokkaido, releasing passive tracers regarded as leaked CO2. Biological impact data were newly compiled, and 4 thresholds for biological impacts depending on both the increase in partial pressure of CO2 (pCO2) and exposure time were set. The increase in pCO2 estimated in the simulation, assuming CO2 leak rates of 1,000 tonnes/y and 10,000 tonnes/y, exceeded no thresholds. The tracer concentration became almost equilibrium within about a week after the commencement of the release, and the increase in pCO2 was much larger in summer than winter. These results suggest that the simulation of leaked CO2 for PEIA be run for about a month in summer, and that monitoring CO2 concentration be also conducted in summer. It is also implied that monitoring pCO2 could detect leakage at O(104) tonnes/y or larger than it.","PeriodicalId":17480,"journal":{"name":"Journal of Water and Environment Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136053525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The efficiency of iron-added sediment microbial fuel cells (SMFCs) in regulating P release from agricultural drainage sediment was investigated in this study. Surface sediment collected from an agricultural drainage canal flowing into Kojima Lake was mixed with iron oxide (Fe2O3) or amorphous iron oxyhydroxide (FeOOH) at 50 mmol kg−1. A 14.6-cm high acrylic pipe was filled with 80 mL of deionized water after 130 g of sediment was placed. A 3 × 3 cm graphite felt was used for the anode in a dual chamber SMFC, while a carbon rod was used for the cathode. Three treatments: No Fe, Fe2O3, and FeOOH, were operated for 408 h under open or closed circuit conditions. Results showed that FeOOH addition lowered P release from sediment regardless of SMFC operational conditions, suggesting that higher P adsorption by FeOOH may mask the effect of SMFCs. Fe2O3 did not reduce total P concentration in the overlying water. In addition, electricity generation was not enhanced by Fe-added SMFCs. Although SMFCs increased sedimentary redox potential, P release was not suppressed by the SMFC operation, indicating that organic P would be released by SMFCs from P-rich sediment.","PeriodicalId":17480,"journal":{"name":"Journal of Water and Environment Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136053504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
