20.500.12556/RUL-167565 Vpliv mikroplastike na rast in razvoj zelenjadnic Effects of microplastics on growth and development vegetables Mikroplastika (MP) je v današnjem svetu prisotna v različnih ekosistemih. Zaradi svoje razširjenosti, obstojnosti in morebitnih negativnih učinkov na žive organizme, postaja onesnaževanje z mikroplastiko pomembno okoljsko vprašanje v globalnem smislu. V diplomskem delu smo opisali značilnosti delcev mikroplastike, njihov izvor in pojavnost v tleh. Osredotočili smo se na kmetijska tla in opisali agrotehnične ukrepe, ki omogočajo vstop delcem MP v tla, kot so namakanje s prečiščeno odpadno vodo, gnojenje z organskimi gnojili in predelanim komunalnim blatom in zastiranje tal z različnimi plastičnimi materiali. Podrobneje smo opisali vpliv mikroplastike v kmetijskih tleh na fizikalne lastnosti tal in posledično na rast rastlin, na njihove morfološke spremembe in biokemične procese. Opisane so lastnosti biorazgradljivih materialov iz katerih nastaja biorazgradljiva mikroplastika in njen vpliv na lastnosti tal in na rastline. Podrobneje so opisani poskusi o vplivu mikroplastike na rast in razvoj redkve (Raphanus sativu L.), fižola (Phaseolus vulgaris L.) in paradižnika (Solanum lycopersicum L.). Microplastics are found in many different ecosystems in the world today. Due to their widespread distribution, longevity and potential negative impact on living organisms, microplastic pollution is becoming an important environmental issue in a global context. In this thesis we describe the properties of microplastic particles, their origin and their occurrence in soil. We focus on agricultural soils and describe the agrotechnical measures that allow microplastic particles to enter the soil, e.g. irrigation with treated wastewater, fertilisation with organic fertilisers and treated sewage sludge, and covering the soil with various plastic materials. We have described in more detail the effects of microplastics in agricultural soils on the physical properties of the soil and consequently on plant growth, morphological changes and biochemical processes. The properties of the biodegradable materials from which biodegradable microplastics are formed and their effects on soil properties and plants are described. Experiments on the effect of microplastics on the growth and development of radish (Raphanus sativus L.), common bean (Phaseolus vulgaris L.) and tomato (Solanum lycopersicum L.) are described in detail. plastika mikroplastika biorazgradljiva mikroplastika plastic microplastics degradable microplastics true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-02-28 07:15:15 2025-02-28 07:15:22 2025-03-01 04:14:47 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 256085 227644675 45603.pdf 45603.pdf 1 EA63152D5EA450DBF6E59922B7F0B4DA b3a92bb5b1b35ca4bf066c3cf33f55c1f66b86167507c0d414d8016dd7aebb0f 855e8d8c-f59a-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200213 Biotehniška fakulteta 0 0 0
