Phthalates and phenols are widely used in the manufacture of everyday household products and are therefore contained in leachate generated in landfills where these products are disposed. These pollutants have endocrine disruptive capabilities and are considered as priority pollutants. Knowledge of their fate in the environment is of relevance to their management and the reduction of associated human and animal exposure risk. Several studies have profiled these pollutants in wastewater, but little information is available on their presence and fate in landfill environments and surrounding soils. Further to this, their degradation pathways have mostly been reported in laboratory simulated studies where the media may not be as complex and dynamic as landfills and surrounding soil environments. The factors and processes affecting their release from waste materials in landfills and their dispersal into surrounding environments has also not been reported, yet this knowledge is relevant for the design of any remediation measures. This article reviews the sources, occurrence, and degradation of phenols and phthalates in landfilled wastes and landfill leachate, and the factors influencing their fate in the landfill and surrounding soils contaminated with landfill leachates. We conclude with a discussion on the exposure pathways and exposure routes of these compounds from landfills to humans and the associated health risk and possible future research opportunities.</p>","PeriodicalId":14121,"journal":{"name":"International Journal of Environmental Research","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141611726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Despite the complexity of determining precipitation distribution, numerous satellite-based precipitation products (SPPs) have been developed in recent decades to estimate precipitation with sufficient coverage and accuracy. This study evaluates the performance of four SPPs, namely Integrated Multi-satellite Retrievals for GPM (IMERG-FRV6), Multi-Source Weighted-Ensemble Precipitation (MSWEP), Tropical Rainfall Measuring Mission (TRMM-3B43V7), and Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks—Climate Data Record (PERSIANN-CDR) on monthly, seasonal, and annual scales in Iran, and aimed to enhance the accuracy of the evaluation by extending the statistical period and selecting evaluation indicators based on error, efficiency, and correlation. Measured rainfall data from 81 synoptic stations across Iran from 2008 to 2019 were used for this evaluation. To accurately assess the selected SPPs, several statistical indices including Correlation Coefficient (CC), Kling-Gupta Efficiency (KGE), Root Mean Square Error (RMSE), and Bias were calculated and analyzed at all synoptic stations. The results demonstrate that MSWEP has a significant advantage over other products at all time scales. The performance of all four products in areas with high monthly rainfall is associated with more errors. PERSIANN-CDR exhibited the highest monthly RMSE, while TRMM-3B43V7 performed better in drier regions with low to moderate precipitation. MSWEP showed the closest average precipitation to observational data in spring, summer, and winter, while IMERG-FRV6 overestimated precipitation in all seasons.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":14121,"journal":{"name":"International Journal of Environmental Research","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

These species were grown at the same location and stage of development. Leaf essential oils were extracted by hydrodistillation using a Clevenger apparatus during the four seasons. Gas chromatography–mass spectrometry (GC–MS) and high-performance thin-layer chromatography (HPTLC) techniques were used to analyze the chemical composition. <i>E. badjensis</i> consistently exhibited a dominant composition, with 1,8-cineole being the predominant component. Notably, the proportion of 1,8-cineole in <i>E. badjensis</i> was 77.35% in spring (SP), 69.46% in summer (SU), 95.30% in autumn (AU), and 89.30% in winter (WI). <i>E. globulus</i> also exhibited 1,8-cineole as its primary constituent, with proportions fluctuating slightly across seasons at 84.87%, 79.94%, 81%, and 85.88%, respectively. The proportions and constituents of various species differed significantly. HPTLC was successfully used as a swift technique to monitor the chemical composition of essential oils (EOs) in various <i>Eucalyptus</i> species during the seasonality.

In response, we describe the Deep learning based Convolutional Gated Recurrent Unit Tempo Fusion Network (CGTFN) model, which represents a considerable development in the evaluation of water quality. The model addresses these restrictions by seamlessly merging Convolutional Neural Networks (CNNs) for spatial pattern recognition and Gated Recurrent Units (GRUs) for temporal interactions. The Tempo Fusion mechanism combines spatial, temporal, and contextual data harmoniously, allowing for more sophisticated classifications by recognizing subtle interdependencies among environmental elements. The pioneering CGTFN model outperforms previous models, achieving 99.71 and 99.81% accuracy on both public-env and real-time-env datasets, respectively, exceeding established models at 98.2%.

Hence, we determine whether the observing nations’ increasing GDP per capita, energy use, and population density intensify greenhouse gas emissions. This study also considers structural breaks in the time-series data from 1990 to 2019. Using the bounds-testing approach, we discover evidence of long-run cointegration among the variables. Furthermore, the long-run autoregressive distributed lag (ARDL) estimations disclose that GDP per capita positively correlates with greenhouse gas emissions, with this effect observed across all sample countries except India in the short run. Additionally, in the long and short run, energy use intensifies greenhouse gas emissions in all sample countries except Bangladesh. Population density also harms the environment in both time horizons in all the observed countries. The study also incorporates fully modified OLS (FMOLS) and dynamic OLS (DOLS) regressions for robust interpretations. Findings of FMOLS and DOLS also support the ARDL model’s outcomes. Moreover, diagnostic tests confirm the stability and reliability of ARDL models. Based on the varying findings on the impacts of energy use on greenhouse gas emissions across countries in the short and long run and the influence of GDP per capita in the short run, policymakers should tailor environmental policies according to nations’ energy and income structures.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":14121,"journal":{"name":"International Journal of Environmental Research","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141517120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
