Detection of microplastics in soil and sediment
Original title: Detection of microplastics in soil and sediment
AI summary Read the abstract
This Croatian-language article reviews methods for detecting microplastics in soil and sediment environments, summarizing the challenges of identifying these small particles given their wide size range and diverse compositions. It highlights how the ubiquity of microplastics in terrestrial and freshwater systems has driven development of improved detection protocols.
Masovna upotreba plastike i neadekvatno odlaganje plastičnog otpada dovelo je do nakupljanja plastike u okolišu. Osim velikih komada plastike problem predstavljaju i male, teško uočljive čestice mikroplastike koje se smatraju jednim od glavnih onečišćivača rijeka, mora, tla i sedimenta. Upravo široka pojavnost mikroplastike u okolišu dovela je do njezinog ulaska u biogeokemijski ciklus i hranidbeni lanac sa štetnim posljedicama za ljudsko zdravlje. Pojava mikroplastike u morima bila je jedan od prvih poticaja za početak istraživanja mikroplastike u okolišu, a manji broj dostupnih istraživanja o mikroplastici u tlu ostavlja velik prostor za daljnja istraživanja na tom području. Pristup istraživanju mikroplastike treba biti temeljit i opsežan, a korištenje još uvijek nestandardiziranih metoda dovodi do rezultata koji se ne mogu uspoređivati. Istraživanje mikroplastike u tlu i sedimentu podrazumijeva određivanje lokacije, prikupljanje uzoraka, izolaciju mikroplastike iz tla i sedimenta, pročišćavanje mikroplastičnih čestica te dobivanje kemijskog sastava izoliranih čestica. U ovom radu dan je literaturni pregled kvalitativnih analitičkih metoda za detekciju i identifikaciju mikroplastike iz tla i sedimenta. Za dobivanje reprezentativnih rezultata važan je korak pravilnog uzorkovanja, a najčešće korištene metode prikupljanja uzoraka su selektivno i skupno uzorkovanje te prikupljanje uzoraka smanjenog volumena. Prikupljeni uzorci izdvajaju se od čestica tla i sedimenta, pročišćavaju te se vizualno identificiraju i sortiraju. Vizualna identifikacija uključuje promatranje golim okom, mikroskopima i bojanje bojama, a čestice se sortiraju prema izvoru i vrsti polimera te fizičkim karakteristikama, kao što su oblik i boja. Detekcija mikroplastike podrazumijeva i dobivanje kemijskog sastava prikupljenih polimernih čestica instrumentalnim metodama Ramanove spektroskopije (RS) te Furierove transformirajuće infracrvene spektroskopije (FTIR). Primjenjuju se i toplinske metode kao što je piroliza-plinska kromatografija u kombinaciji sa masenom spektrometrijom (pyr-GC/MS).
