Abstract
Mikroplastikoak (MP) ingurumenerako gai arriskutsutzat hartzen dira dauzkaten gehigarriak askatzeko eta bestelako kutsatzaileak garraiatzeko eta kontzentratzeko gai direlako. Sugar-atzeratzaile polibromatuak (BFR) plastikoetan asko erabiltzen diren gehigarriak dira eta ikerketek erakusten dute behin ekosistemetara isurtzen direnean efektu toxiko nabarmenak dituztela. Lan honetan akrilonitrilo butadieno estirenozko (ABS) MP-tan dagoen Deka-209-aren migrazioan gazitasunak eta erradiazio ultramoreak duten eragina aztertzen da ur-sistema natural bat simulatuz, X izpien mikrofluoreszentzia (μ-XRF) analisi-teknika gisa erabiliz. Horrela, gazitasun baxua eta UM erradiazioaren presentziak BFRaren migrazioa errazten dutela frogatu da.
Microplastics (MPs) are considered dangerous for the environment because they can release their additives and concentrate pollutants from the environment. Brominated flame retardants (BFRs) are widely used as additional compounds in all kinds of plastics and studies show that they have highly toxic effects. This work focuses on studying the influence of salinity and ultraviolet radiation on the migration of Deca-209, contained in MPs of acrylonitrile butadiene styrene (ABS) simulating a natural water environment, using the X-ray microfluorescence (μ-XRF) technique as an analysis method to monitor the whole process. The results showed that the presence of low salinities and UV radiation makes the migration of the FR easier.
