The local correlation coefficients obtained from the GWPCC ranged from negative to the highest values of 0.80, 0.92 and 0.86, respectively, which were significantly higher than the results of traditional Pearson correlation coefficients. These patterns were associated with impure limestones, Zn mineralization, and phosphate fertilizer inputs. Furthermore, the RF model ranked Zn (39.4 %) and P (17.6 %) as the most influential factors, with their importance increasing in limestone-dominated areas (50.9 % and 27.4 %), which emphasized the external contributions from local Zn mineralization and phosphate fertilizers in addition to natural accumulation.</div></div><div><h3>Conclusion</h3><div>This study demonstrated the effectiveness of integrating SML techniques with geochemical analysis for identifying Cd sources in the topsoil of Ireland, highlighting the roles of lithology and agricultural activities in Cd accumulation.

A mass transfer model for characterizing the emissions of D5 from human skin lipids is developed, which incorporates the adsorption/desorption effect of D5 onto indoor surfaces that was ignored previously. A long-term field campaign in residence was conducted to examine the D5 emission behaviors, showing a number of concentration peaks after using personal care products. Special enhanced-ventilation and emission experiments were designed to determine the mass transfer parameters in the model via a hybrid optimization method, which were then used to predict D5 concentrations in some other test days. Good agreement between model predictions and observations demonstrates the effectiveness of the model and measured parameters. Feature importance analysis on indoor D5 transport is further performed, indicating that air exchange rate is the most important factor compared with temperature and relative humidity. This study comprehensively uncovers the transport dynamics of D5 in realistic indoor settings, which is helpful for human-related source characterization and control.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"275 ","pages":"Article 121457"},"PeriodicalIF":7.7,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690749","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}

The results show that MP particles migrate northward under the gravity flow and jacking flow. The average time required for MPs to reach the northern lakes in jacking flow was 21.29 % shorter than that in gravity flow. Instead, MPs undergo reverse movement driven by back flow. The difference in migration rates due to MPs physical properties can reach up to 36 % in the same flow regime.

In addition, the accumulation hotspots of MPs under three flow regimes were investigated, and MP monitoring in the corresponding areas based on the flow regime can effectively reduce the ecological risk.
