Microplastic counts and polymer type in analysis-required aliquots of sediment samples from the Kuril Kamtchatka Trench
AI summary Read the abstract
This data table records the microplastic counts and polymer types identified in sediment samples from the Kuril-Kamchatka Trench in the deep Pacific Ocean. The samples were fully analysed by micro-FTIR spectroscopy to ensure accurate quantification of particles down to the detection limit.
This data table provided information about the microplastic identification analysis carried out on the samples listed in the data set doi:10.1594/PANGAEA.928575. To guarantee a precise quantification of particles, the sample were analysed entirely by µFT-IR. This procedure requires an aliquoting of the samples in subsamples. The number and the volume of subsamples, in the table depict as % aliquot, were established after calculating the number of particles present in each sample, to avoid an overload of the filter necessary to carry out the spectroscopic measurement. By summing the outcomes of the aliquots of a sample, the total number of MP and polymer type per sample was established.
