O rio Paranaíta, importante tributário da bacia Teles Pires, tem sido impactado por processos antrópicos devido principalmente à agropecuária e hidroenergia. Analisar as dinâmicas geoambientais das bacias hidrográficas amazônicas é fundamental para construção de estratégias gestão ambiental territorial, e, estas perpassam inicialmente pela identificação características dos sistemas ambientais, a partir diagnósticos que considerem integração diferentes elementos paisagem, como dinâmica geoambiental hidrológica. estudo objetivou analisar qualidade água na do baixo Paranaíta. A caracterização foi realizada geoprocessamento dados geoespaciais disponibilizados em bases oficiais avaliação com amostragens in loco análises laboratoriais.

Fish farming is increasingly important globally and nationally, playing a crucial role in fish production for human consumption. Monitoring microbiological chemical contaminants from water discharge essential to mitigate the risk of contaminating This study analyzes physicochemical E. coli parameters tambacu muscles (Colossoma macropomum × Piaractus mesopotamicus) Western Maranhão, Brazil. It also includes qualitative characterization zooplankton ponds. Samples were collected ponds dam system fed by natural watercourses Tocantins River tributaries, located at connection Brazilian savanna Amazon biomes. The did not meet national standards. community included Rotifera, Cladocera, Copepoda, Protozoa representatives, with no prior studies on region, making these findings unprecedented. biological quality freshwater farming, as poor can lead decreased productivity mortality, raising significant food safety concerns. studied related potential influence untreated wastewater source contamination, leaving region still far safe reuse practices. contamination waters concern health emphasize need appropriate regulations.

Abstract River Danro in Garhwa (India) plays a vital role as significant source of surface water and crucial tributary the North Koel River, ultimately joining Ganga Basin. Serving both urban-industrial rural areas, region faces challenges, including sand mining near Belchampa Ghat. This study aimed to assess physicochemical heavy metals pollution at nine sampling locations, utilizing Overall Index Pollution (OIP), Nemerow (NPI), Heavy Metal (HPI). OIP values indicated excellent quality (0.71) non-monsoon slight (6.28) monsoon. NPI ranged from 0.10 1.74 0.22 (clean) 27.15 (heavily polluted) HPI results suggested groundwater contamination, particularly by lead. Principal component analysis (PCA) geospatial mapping showed similar outcomes, highlighting influence adjacent land use on quality. Recognizing significance sustaining life, livelihoods, economic growth, recommends implementing measures like floating bed remediation regulatory actions for effective river management.

For a given aquatic ecosystem that will be used as water source, it is necessary to establish the quality of from microbiological point view by identifying pathogens present in water. The aim this study was determine and analyze antimicrobial activity some biocides derived garlic (garlic–methanol extract) lavender (lavender–water extract). Their efficiency evaluated at different concentrations contact times. Initially, through specific laboratory analyses, characteristics river were determined. Biomimetic studies on based surface waters involved detailed exploration how natural properties these plants can effectively utilized treat contaminated with harmful microorganisms. Both time amount biocide have significant effect microorganisms interest. Thus, describe degradation rate coliform bacteria, pseudo-first-order zero-order kinetic model used, r=−(dN/dt)=kobs·t şi r0=kobs·N0=k0, where r (CFU/min), N0 initial number aqueous solution (colony-forming unit, CFU), N final after t (CFU), kobs constant (min−1), (min), r0 k0 pseudo-rate zero order (min−1). Following 60 min treatment 1 mL lavender-water biocide, inhibition pathogenic reached 59.09%, whereas, under same conditions, garlic–methanol achieved an 40.86%. This confirms both biocides, highlighting their potential mitigating pollution caused pathogens.
