      <abstract xml:lang="en" contentType="abstract">The dataset contains data that has been collected and processed in a laboratory based transport study of microplastic (MP) fibres by deep-burrowing earthworms (Lumbricus terrestris). The experiments included were 1) a transport study assessing the time-dependent redistribution of microplastic fibres by earthworms in soil columns (E1), 2) a study to assess which microplastic fibre lengths were ingested by earthworms (E2). 
For E1, MP fibres were mixed into the top 2 cm of a 30 cm thick soil column, earthworms added and the MP fibre redistribution measured after 2 and 4 weeks.  The depth-dependent distribution of MP fibre mass was measured using the metal-dope of added MP fibres and MP fibre length by optical microscopy. The control treatment for E1 was with MP fibres but without earthworms. 
For E2, MP fibres were mixed homogeneously with all of the soil and then packed to 30 cm thick soil columns, earthworms added and collected after 2 weeks; then the earthworms were depurated in petri dishes and the earthworm casts collected, dried and analysed for MP fibre lengths. The control treatment for E2 was with earthworms but without MP fibres. MP fibre lengths were determined with optical microscopy. For more detail see the associated publication.</abstract>
      <abstract xml:lang="sv" contentType="abstract">Datasetet innehåller data som har samlats in och bearbetats i en laboratoriebaserad transportstudie av mikroplastfibrer (MP) av djupgrävande daggmaskar (Lumbricus terrestris). Experimenten omfattade 1) en transportstudie för att bedöma den tidsberoende omfördelningen av mikroplastfibrer av daggmaskar i jordkolonner (E1), 2) en studie för att bedöma vilka mikroplastfiberlängder som intogs av daggmaskar (E2). 
För E1 blandades MP-fibrer i de översta 2 cm av en 30 cm tjock jordkolonn, daggmaskar tillsattes och omfördelningen av MP-fibrer mättes efter 2 och 4 veckor. Den djupberoende fördelningen av MP-fibermassan mättes med hjälp av metaldopningen av tillsatta MP-fibrer och MP-fiberlängden med optisk mikroskopi. Kontrollbehandlingen för E1 var med MP-fibrer men utan daggmaskar.
För E2 blandades MP-fibrerna homogent med all jord och packades sedan till 30 cm tjocka jordkolonner, maskar tillsattes och samlades in efter 2 veckor; därefter renades maskarna i petriskålar och maskavföringen samlades in, torkades och analyserades med avseende på MP-fiberlängder. Kontrollbehandlingen för E2 var med maskar men utan MP-fibrer. MP-fiberlängderna bestämdes med optisk mikroskopi. För mer information, se den tillhörande publikationen.</abstract>
