Such models are also adopted in their direct form to estimate lake <em>TP</em> concentrations following hypothetical external load reductions. However, such approaches suffer from extreme parameterisation and often give inaccurate results. Process-based coupled ecological-hydrodynamic models offer a much wider flexibility and produce an extensive set of information, solving many of the issues of Vollenweider-OECD-type models. However, their application has been up to now restricted to single lakes due to calibration effort and data availability burdens. To overcome these obstacles, in this study we developed a simplified application of the process-based coupled model QWET over 9 lakes in Northern Italy, making use of the ParSAC automatic calibration tool and feeding the models only with general data available from public monitoring. QWET models were calibrated over past observations, simulating nutrient reduction scenarios for the near-future decades. The advantages over traditionally employed models for lake water protection planning at the regional scale were hence identified through a practical application, determining the strengths and limits of the herein-adopted simplified process-based approach over lakes with different features.

Hypoxia reduces iron ions, leading to P release through biogeochemical reactions associated with organic matter degradation, which in turn depletes dissolved oxygen (DO) in the sediment. The application of bubble technology is beneficial, as microbubbles (MBs) effectively remove P and enhance DO levels in both the overlying water and sediment surface. To identify the optimal bubble size for application, we conducted a series of flotation experiments and P fractionation studies using MBs and nanobubbles (NBs). Results indicate that NBs achieved a flotation efficiency of 12 %, MBs reached 44 %, and the combined use of NBs and MBs attained the highest flotation efficiency at 62 %, confirming that a combination of bubble sizes can enhance flotation efficiency. Furthermore, the introduction of air bubbles to mitigate hypoxia in the overlying water increased DO concentrations from 1 to 5 mg/L, followed by a gradual decline. P release in the bubble-injected groups was up to three times lower than in the control group. Water quality profiling of P distribution in sediments revealed a significant increase of approximately 10 % in iron-bound P under aerobic conditions, highlighting its critical role in regulating P release. Our findings suggest that utilizing a combination of bubble sizes, including NBs, enhances P removal efficiency and improves the anaerobic conditions of the lake's bottom layer, thereby further reducing P release from sediments.</div></div>","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"268 ","pages":"Article 104466"},"PeriodicalIF":3.5,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142693027","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}

Higher rainfall intensity in loamy sand soil columns resulted in an increased washout of LDPE, PBAT, and starch-based particles by 92 %, 144 %, and 85 %, respectively, compared to low rainfall intensity. In sandy loam soil, increased rainfall intensity resulted in a significantly higher washout of LDPE, PBAT, and starch-based particles with percentages of 93 %, 69 %, and 45 %, respectively.
