Kev puas tsuaj ntawm polypropylene haus lub kaus mom ua rau muaj qhov txawv thiab ntau yam kev hem thawj rau marine ecosystems. Raws li cov pa paug yas ntim hauv ntiaj teb cov dej hiav txwv, cov kaus mom dej haus yog ib qho ntawm cov khoom siv ntau tshaj plaws nyob rau ntawm ntug dej hiav txwv thiab hauv qhov tob - hiav txwv sediments. Qhov cuam tshuam ntawm cov kaus mom no txuas mus deb tshaj qhov yooj yim pom muaj kuab paug; Cov txiaj ntsig ntawm lub cev thiab tshuaj lom neeg ntawm lawv qhov kev puas tsuaj yog hloov cov chaw hauv dej hiav txwv ntawm qib microscopic.
Thaum PP lub kaus mom raug pov rau hauv dej hiav txwv, lawv raug rau kev ua haujlwm tsis tu ncua ntawm nthwv dej, dej ntws, thiab kev sib tsoo nrog xuab zeb, pob zeb, thiab lwm yam khib nyiab. Cov nyhuv "tumbling" no ua zoo li lub pob zeb ntuj, tsis tu ncua sib tsoo ntawm lub kaus mom. Kev tshawb fawb simulating puam ib puag ncig tau pom tias kev ua haujlwm puas tsuaj tiv thaiv cov xuab zeb ntxhib thiab pob zeb ua kom nrawm nrawm ntawm microplastics tawg. Cov txheej txheem no tsis yog tsuas yog ua kom muaj cov khoom yas hauv cov kab dej tab sis kuj hloov lawv cov chemistry nto. Raws li lub kaus mom abrade, lawv thaj chaw saum npoo nce, thiab lawv tsim cov kab nrib pleb thiab roughness, uas txhim kho lawv lub peev xwm los adsorb thiab mloog cov pa phem hydrophobic tam sim no hauv dej hiav txwv, xws li cov pa phem tsis tu ncua (POPs) thiab cov hlau hnyav.
Cov tshuaj lom neeg "loaded" microplastics dhau los ua cov kab mob lom nyob rau hauv cov khoom noj hauv hiav txwv. Zooplankton thiab lwm yam kab mob me me ua rau cov me me, abrasive PP fragments rau zaub mov. Thaum noj, qhov ntse, abrasive npoo ntawm microplastics tuaj yeem ua rau lub cev puas tsuaj rau lub plab zom mov ntawm marine lub neej, ua rau muaj kev mob sab hauv, txo qis noj, thiab tshaib plab. Tsis tas li ntawd, cov leaching ntawm cov tshuaj additives siv nyob rau hauv lub cap lub manufacturing-xws li plasticizers thiab stabilizers- tuaj yeem cuam tshuam cov kab mob endocrine ntawm cov tsiaj hiav txwv. Cov nyhuv cumulative yog degradation ntawm marine biodiversity, raws li cov abrasive muaj ntawm cap-miv microplastics cuam tshuam kev noj qab haus huv ntawm cov kab mob nyob rau hauv lub hauv paus ntawm cov zaub mov, nrog repercussions echo mus txog rau cov ntses loj, marine mammals, thiab thaum kawg, tib neeg seafood neeg siv.
