The power of multi-matrix monitoring in the Pan-Arctic region: plastics in water and sediment

Abstract: Litter and microplastic assessments are being carried out worldwide. Arctic ecosystems are no exception and plastic pollution is high on the Arctic Council’s agenda. Water and sediment have been identified as two of the priority compartments for monitoring plastics under the Arctic Monitoring and Assessment Programme (AMAP). Recommendations for monitoring both compartments are presented in this publication. Alone, such samples can provide information on presence, fate, and potential impacts to ecosystems.

“…It is therefore important that studies take a crossenvironmental, multi-indicator focus approach to ascertain the most complete picture of plastic pollution. 28 Plastic size adds complexity to what can be monitored and has several constraints. First, the design of sampling devices and methods must be different for small-sized particles as they cannot be accurately collected by, for example, manta trawl nets.…”

“…This methodological approach has long been used within plastic research, and it is a recommended tool for monitoring (e.g., refs , , ). A manta net can obtain replicable data for particles >300 μm, although it is limited by use in coastal areas and highly weather dependent . Manta nets can be used if limitations are clearly acknowledged.…”

“…Although local sources and pathways, e.g., rivers [177,57,197], wastewater effluents [132,64,186,79], garbage dumping sites [65], and industries [68,128] may contribute significantly to marine plastic pollution in the Arctic we have little knowledge about the quantity and quality of plastic pollution originating from them. One approach to distinguishing different sources can be to measure typical signatures of MPs in a given water mass [127,135]. MP compositions have been observed to differ between water masses, sediment types and environmental matrices where, e.g., sea ice contains more fragments [150,102,186] than seawater, which is often dominated by fibres [127,186,120,159].…”
