Through fish species collected in Lake Janauacá and the Anavilhanas Archipelago, in the state of Amazonas, Brazil, we investigated the ingestion of microplastics by Amazonian fish species with different eating habits. The fish were dissected, and the gastrointestinal tract underwent alkaline digestion for the separation of the microplastic particles. Using a stereomicroscope, the items characterized as microplastics were subjected to Fourier-transform infrared spectroscopy. Almost >60% of the analyzed fish species contained microplastics in their gastrointestinal tracts. Most of the microplastics were found in the intestine (91.5%) and the rest (8.5%) in the stomach. There were no significant differences in the feeding habits of the studied species, or between the locations. The characterization of microplastics highlights the possible sources of the microplastics such as discarded fishing artifacts, the lack of basic sanitation evident in the region and the lack of environmental education for tourists. This study provides data that can assist in the development and formation of practices that combat plastic pollution and raises awareness in regard to the correct disposal of plastics.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97Suppl 3 Suppl 3","pages":"e20241204"},"PeriodicalIF":1.1,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144607195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two samples ground (dry) in a planetary ball mill up to 32 h were examined using laser scattering, physisorption, electron microscopy, X-ray diffraction, infrared spectroscopy and thermal analysis. Static hardness and crystal grain sizes were measured in parent rock specimens. For limestone, the apparent grinding limit (12 µm) was reached after 1 h, and no changes were observed in lattice strain, crystallite size and infrared bands related to CO32- vibration modes. For dolostone, these properties changed significantly when the grinding limit (6 µm) was achieved (8 h). Calcite-aragonite transformation was mostly observed in intensely ground dolostone. The activation energy for thermal decomposition of calcite and dolomite was correlated with lattice strain and particle agglomeration. The lower grinding rate noticed for dolostone was attributed to its refined grain size. Distinct energy dissipation mechanisms were portrayed once the grinding limit was reached: agglomeration and deagglomeration cycles in limestone; plastic deformation and growth of strong agglomerates in dolostone.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 3","pages":"e20240970"},"PeriodicalIF":1.1,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study sampled 34 sites in the Xingu and Intermediate reservoirs, measuring the variables pH, conductivity, oxygen, and temperature. We used linear models to assess the relationship between macrophytes and environmental characteristics. Aquatic macrophytes, identified and categorized into life forms, showed significant variation in species richness. Results indicated that pH negatively affects macrophyte richness. Most species were emergent, belonging to Poaceae and Cyperaceae families. The study underscores the importance of pH in determining macrophyte diversity, possibly due to the ecophysiological responses of macrophyte to ionic variations. Temperature was a determining factor for the occurrence of emergent species. We highlight the need for further research on how environmental changes impact aquatic ecosystems, especially considering ongoing and future dam projects in the Amazon biome.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 3","pages":"e20240742"},"PeriodicalIF":1.1,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to enhance the analysis of microplastics in aquatic environments by focusing on the optimization and integration of advanced characterization techniques, such as Fourier Transform Infrared Spectroscopy and Raman Spectroscopy. The goal is to improve accuracy in identifying the polymers that makeup microplastics, which is crucial for developing effective strategies for mitigating and controlling aquatic contamination. To this end, the application of Surface-Enhanced Raman Spectroscopy is suggested in this review article, as it significantly improves signal-to-noise ratio, enabling more detailed detection of plastic residues and adsorbed microorganisms. These integrated analyses facilitate the acquisition of more robust and detailed data, essential for formulating effective solutions to the microplastics problem. Additionally, FTIR and Raman spectra were generated for polymers commonly found as microplastics, such as PP, LDPE, PS, and PVC, due to their widespread use in various materials. These standards will provide crucial data for identifying unknown microplastics, significantly contributing to the accuracy and reliability of the analyses.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 suppl 3","pages":"e20241313"},"PeriodicalIF":1.1,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared studies in different countries, ecosystems and type of samples, and identified gaps and needs for futures research. Although research and the complexity of studies have increased over the years, Tropical freshwater ecosystems are still understudied. We emphasized the need for more studies in African countries and Tropical Australia, as well as in reservoirs across all Tropical regions. It is also crucial to evaluate contamination related to flooding dynamics and in aquatic invertebrates.

Although this groundwater is often considered a high-quality source suitable for consumption, it may contain elevated concentrations of Uranium (U) due to the regional lithological geochemistry. The study area, located in São José do Vale do Rio Preto (Rio de Janeiro, Brazil), features a complex geological composition that influences the hydrochemical in the region's fractured aquifers. This research primarily aimed to investigate the factors contributing to high levels of U in groundwater in this region. Advanced geophysical techniques were employed, including gamma-ray spectrometry to assess radioelement concentrations and magnetometry to map structural directions in the area. The study mapped contamination patterns both on the surface and subsurface, establishing a precise correlation between groundwater flow dynamics and the influence of the Central Tectonic Boundary (CTB), a significant transpressive shear zone affecting the regional geological structure. In addition to the geophysical data analysis, the research evaluated the impact of local geological formations on U distribution in well samples. By integrating these results, the study clarified the relationship between geological formations, groundwater flow, and U contamination. This understanding can guide strategies to mitigate water quality issues and provide insights for more effective groundwater management practices in the region.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 3","pages":"e20240609"},"PeriodicalIF":1.1,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leaves or roots of the donors were each mixed at ratios of 0.75, 1.5 and 3% (litter/soil) with soil samples collected in the same areas where they spontaneously co-occur with their target species.

The native A. bicornis stimulated the growth of the two native species and of S. elata but inhibited the growth of the exotic M. minutiflora, in line with the homeland security hypothesis. Our studies suggest that allelopathy may have a part in the invasiveness of A. gayanus and that the inhibitory effect of A. bicornis on the growth of M. minutiflora might help to control the spread of this exotic grass.
