Microplastics　(MPs)　are　plastic　fragments　with　particle　sizes　smaller　than　5　mm　that　have　potentially　harmful　effects　on　ecosystems　and　human　health.　The　soil　environment　is　not　only　the　source　but　also　the　sink　of　MPs.　Thus,　it　is　necessary　to　fully　understand　the　pollution　and　distribution　of　MPs　in　soils.　In　this　study,　Qinghai　Province,　northeast　of　the　Qinghai–Tibet　Plateau,　was　selected　as　the　research　area,　and　22　soil　samples　were　collected　and　analyzed　to　study　the　levels　and　distribution　characteristics　of　MPs　in　grassland　soils.　MPs　were　obtained　from　the　soils　by　using　density　separation,　and　a　laser　confocal　micro　Raman　spectrometer　was　used　for　MP　identification.　The　results　showed　that　MPs　were　detected　in　all　of　the　soil　samples.　The　total　abundances　of　MPs　ranged　from　1125　to　1329　items/kg,　with　a　mean　abundance　of　1202　items/kg.　Various　types,　shapes,　sizes,　and　colors　of　MPs　were　observed.　Polyethylene　terephthalate　(PET)　was　the　dominant　polymer　in　all　the　grassland　soil　samples.　The　size　range　of　10–50　μm　accounted　for　50%　of　all　identified　MPs.　Pellets　were　the　dominant　MP　shape,　and　colored　MPs　accounted　for　64%　of　all　MPs.　The　results　revealed　the　presence　of　large　quantities　of　MPs　in　the　grassland　soils　of　remote　areas　as　well.　This　study　can　act　as　a　reference　for　further　studies　of　MPs　in　terrestrial　systems.　At　the　end　of　the　paper,　the　prospects　and　suggestions　for　pollution　control　by　soil　MPs　are　given.　©　2023　by　the　authors.
