Low plastic pollution at the world's largest sandy desert
AI summary Read the abstract
Researchers assessed plastic litter levels across the Rub al Khali, the world's largest sandy desert spanning 500,000 km2 in the Arabian Peninsula, combining drone-based macrolitter surveys with microplastic assessments across dunes, finding relatively low plastic pollution despite proximity to major cities, interpreted in the context of local wind and dune dynamics.
The Rub Al Khale (ëmpty quarter)̈ is the largest sandy desert in work, located in the Arbian Peninsula where it extends across 500,000 Km2. The Rub al Khale is boardered by major cities, including Doha, Dubai, Abu Dhabi and Riyadh, among others, but lacks permanent population and it is seldom visitor, mostly by bedouine hunters. Here we report of an assessment of plastic litter in the Rub Al Khale, resulting from a survey conducted in 2020, combining macrolitter assessments using drones with microplastic assessments aross a range of dunes. We interpret the results on the light of the dynamics of flows of materials in deserts and suggest what role deserts, whcih are biomes that have been poorly studied in plastic pollution research, may be in plasic flows in the biosphere.

Low plastic pollution at the world's largest sandy desert
AI summary Read the abstract
Researchers assessed plastic litter in the Rub Al Khali, the world's largest sandy desert spanning 500,000 km2 across the Arabian Peninsula, combining drone-based macrolitter surveys with microplastic sampling across dunes. Despite bordering major cities, the desert showed low plastic pollution levels, interpreted in the context of aeolian transport dynamics and the region's sparse human activity.
A neglected transport of plastic debris to cities from farmland in remote arid regions
AI summary Read the abstract
Researchers found that wind erosion in semiarid farmland regions transports significant quantities of plastic debris, including microplastics, to distant urban areas, identifying a previously neglected long-range transport pathway in arid environments.
Microplastics in the Lut and Kavir Deserts, Iran
AI summary Read the abstract
Researchers collected soil samples from various geomorphological features in Iran's Lut and Kavir deserts — two of the most remote and arid environments on Earth — and found microplastics at all sites, demonstrating that plastic contamination has reached even extreme desert environments far from human activity.
Microplastic abundance and distribution in a Central Asian desert
AI summary Read the abstract
Microplastics were found in desert sediments of Central Asia at concentrations similar to levels reported in some ocean surface samples, with fibers dominating and their deposition attributed to wind-driven atmospheric transport, establishing that even arid, sparsely populated deserts are not immune to global microplastic dispersal.
Microplastic in an Arid Region: Identification, Quantification and Characterization on and Alongside Roads in Al Ain, Abu Dhabi, United Arab Emirates
AI summary Read the abstract
Researchers characterized microplastic contamination in road dust, roadside soils, and stormwater runoff in Al Ain City, Abu Dhabi, identifying tire wear material, fibers, and degraded plastic bag and bottle fragments as dominant particle types and finding that Aeolian (wind-driven) transport is likely more important than water transport in this arid region.
