Geoelectrical evaluation of overburden protective capacity in an Alluvial deposit microenvironment in the vicinity of an industrial district, southwest Nigeria: Insights on aquifer vulnerability and groundwater contamination

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: June 24, 2024

In this study, electrical resistivity techniques were employed in the evaluation of overburden protective capacity at a location designated for industrial activities southwest Nigeria. 40 VES stations and 6 imaging traverses occupied using Schlumberger Wenner configurations respectively. Results indicate presence typical multi-layered aquifer aquitard system, presumably composed sand, clayey clay hard clay. Predominant phreatic (unconfined) sand/clayey sand aquifers mapped shallow depth (< 5m) are not suitable long term sustainable groundwater development, since volume quality vary with seasons. 70% surveyed locations underlain by much deeper (5.0-68.0 m) aquifer. The occurrence impermeable range 29-71 Ωm thickness 2.5-10.0 m and/or 818-2557 1.4-52.4 is depicted across 20 locations. Clay materials lithological barriers to pollutants infiltration into zone. However, fractures compacted consolidated can serve as pathways rapid movement water dissolved contaminants systems. rating exhibits abysmally poor (0.0027-0.0813 S) 27 (67.5%) l; weak (0.1044-0.1824 9 (22.5%) moderate (0.348-0.472 4 (10%). These values suggest high probability migration resources. This also supported transverse resistance (filtration coefficient).

Lost in the Dark: Current Evidence and Knowledge Gaps About Microplastic Pollution in Natural Caves

Environments, Journal Year: 2024, Volume and Issue: 11(11), P. 238 - 238

Published: Oct. 29, 2024

In this study, a systematic review of the scientific literature was carried out to summarize emerging evidence on microplastic pollution in natural caves. After screening 655 papers topic from combined search Web Knowledge and Scopus databases, we found only 14 studies reporting quantitative data microplastics total 27 Most assessments focused water sediment, with very limited investigations concerning cave biota. Overall, most common types particles caves were small (<1 mm) fibers (~70–90% items), transparent or light-colored, mostly made polyethylene terephthalate. Anthropogenic cellulosic materials, however, represented non-negligible portion (i.e., ~20–30%). Microplastic concentrations varied between 0.017 911 items/L for 7.9 4777 items/kg thus falling within levels other terrestrial, freshwater, marine environments. Levels appear largely variable among caves, stressing need extend geographic environmental ranges assessments, which are currently concentrated Italian land, few case regions world Despite their putative isolation, have high vulnerability contamination, requiring much more research effort understand potential risk that plastics pose these fragile ecosystems.
