AB  - Marine litter and microplastic pollution in mangroves pose significant threats. 
      This study of litter in Omani mangroves revealed an average density of 0.83 to 
      21.92 items/m(2). Quriyat lagoon emerged as the most contaminated area, hosting 
      133 items/m(2), while Qurum Natural Reserve lagoon showed the least contamination 
      at 10 items/m(2). Plastics constituted 73-96 % of the litter, with microplastic 
      levels in sediment ranging from 6 to 256 pieces/kg. Al-Sawadi's lagoon had the 
      highest microplastic abundance (27.52 +/- 5.32 pieces/kg), in contrast to Al 
      Qurum's Marine Protected Area with the lowest (0.60 +/- 1.12 pieces/kg). 
      Microplastics, categorized as fragments, pellets, and fibers, were distributed 
      across zones 40.05 % landward, 30.97 % seaward, and 28.98 % in the middle 
      mangrove zones. Primary plastic polymers identified were Polyethylene (PE) at 
      40 % and High-Density Polyethylene (HDPE) at 28 %, along with others found in 
      specific areas. Our findings provide essential baseline data for future 
      monitoring efforts and management strategies in Oman and other countries.
