Research data management plan for HRZZ project IP-2022-10-3824 MIcroplastic and Nanosilver InteractiONs in terrestrial and freshwater plants and algae (MINION)

AI summary Read the abstract

This data management plan outlines the protocols for the MINION project (HRZZ IP-2022-10-3824), which investigates interactions between microplastics and nanosilver in terrestrial and freshwater plants and algae. The plan describes data collection, storage, and sharing strategies for studying how plastic particle size and polymer type influence toxicity in exposed organisms.

Potražnja za plastikom kontinuirano raste u različitim područjima ljudskih aktivnosti, a velik dio proizvedene plastike završava u okolišu kao otpad, stvarajući tako značajan ekološki izazov. Budući da nije biorazgradiva, plastika ostaje u okolišu jako dugo pa je plastični otpad pod kontinuiranim procesom razgradnje koji dovodi do fragmentacije plastike na manje dijelove, od većih plastičnih ostataka do mikro (MP) i nano (NP) ) dimenzija čestica. Čestice plastike ostaju u kopnenom i vodenom okolišu te u atmosferi i time ugrožavaju živi svijet. Dimenzije plastike i njezina sposobnost adsorpcije toksičnih organskih i anorganskih zagađivača, kao i osnovna struktura polimera, ključne su varijable u određivanju razine toksičnosti plastike u izloženim organizmima. Posebno su zanimljive studije koje se bave interakcijama između MP i nanočestica metala, posebice nanočestica srebra (AgNP), zbog njihove široke rasprostranjenosti u tlu, vodi i zraku te njihove toksičnosti za većinu organizama. U našem projektu predlažemo inovativno istraživanje o interaktivnim učincima MP i AgNP na biljke i zelene alge, ključne komponente svakog ekosustava i prehrambenog lanca. U projektu ćemo istražiti dvije vrste mikroplastike (PS-MP i PMMA-MP) i AgNP s dvije vrste omotača (PVP- i CTAB-AgNP) na kopnenoj biljci Allium cepa, vodenoj biljci Lemna minor i zelenoj algi Chlorella vulgaris kako bi se razjasnila priroda njihove interakcije i o čemu ona ovisi. Štoviše, predloženi su inovativni pristupi lokalizaciji i detekciji MP. Saznanja o interakcijama MP i AgNP općenito su vrlo skromna, a za biljke i zelene alge do sada postoji samo jedna objavljena studija.
