Sunkiųjų metalų sąveikos su dirvožemio mikroorganizmais literatūros apžvalga

Published: June 13, 2024

Žmonių veikla (pramonė, žemės ūkis, kasyba, sąvartynai) susijusi su dirvožemio tarša sunkiaisiais metalais. Ši neigiamai veikia visus gyvus organizmus, įskaitant ir mikroorganizmus. Esant nedidelei sunkiųjų metalų koncentracijai mikroorganizmai gali pašalinti juos. Darbo tikslas: išanalizuoti sąveiką mikroorganizmais remiantis pateiktais moksliniais straipsniais. Tiriamas užterštumas įvairiais metalais, bet daugiausiai analizuojami kadmis, varis, švinas. Moksliniuose straipsniuose atliekami fitoremediacijos tyrimai, skirti ištirti ryšiui tarp mikroorganizmų naudojant augalus. Taip pat tyrimai dirvožemį, užterštą vykdant antropogeninę veiklą. Literatūroje aprašomi metalais užteršto kurie atskleidžia panaudojimo galimybes bei jų pokyčius laikui bėgant.

Examining the swelling potential of cohesive soils with high plasticity according to their index properties using GIS

Open Geosciences, Journal Year: 2024, Volume and Issue: 16(1)

Published: Jan. 1, 2024

Abstract As the value ranges presented in literature with tables and graphs that feature soil index properties related to swelling potential are intertwined, their interpretation may pose certain challenges. In this study, spatial distribution maps of were created using data obtained from research, those values study area assessed by combining all maps, resulting a single comprehensive map new limit high plasticity cohesive soils. Soils evaluated according newly determined ranges. The findings show soils region should have parameters potential. for demonstrate are: % natural water content <18, passing through #200 sieve >90, liquid >65, >21, pressure >240 kPa, percentage >6.
