This study estimated the concentration of microplastics (i.e. plastics measuring less than 5mm; reported in unit of particles/kg d.w) in sediments from the northern Tyrrhenian Sea collected from 2017-11-07 to 2017-11-09. Microplastics were collected using a Van Veen grab. This dataset contains the results from all 29 sediment samples, in a spreadsheet format.

Processing Steps
  • Parameter or Variable: microplastic concentration (measured); Units: particles per kg dry sediment; Observation Category: in situ; Sampling Instrument: Van Veen grab; Sampling and Analyzing Method: The survey was conducted in the framework of a project whose main objective was to provide information on benthic invertebrates in the Northern Tyrrhenian, however anthropogenic waste data were also gathered. The study area was a stretch of sea (named Piombino channel) comprised between the Gulf of Follonica (Tuscany) and Elba Island, in the northern Tyrrhenian Sea. This channel is affected by the heavily impacted seaway connecting the port of Piombino (continent) to the port of Portoferraio (Elba Island), and by land-based pollution sources. The sampling campaign was carried out in November 2017: along a 31 km-long transect, duplicate sediment samples from 29 stations at depth varying between 1.0 and 71.5 m were collected with a Van Veen grab. Sediments were sieved on board on a 1 mm mesh, so the smallest size of gathered particles was 1 mm. A 400 g-subsample was used for determination of sediment dry weight and grain size distribution. The transect was divided into 3 sections. The section called “Piombino” includes the stations (from PB1 to PB10) included in the Gulf of Follonica. The section called “Portoferraio” includes the stations (from PF1 to PF14) included in the bay of Portoferraio, while the section called “Offshore” includes all the stations (from OFF15 to OFF25) in the stretch of open sea At the laboratories, the plastic debris in sediment samples were removed under a dissection microscope (Nikon SMZ45T, magnification 3.35-300×), counted, and measured.; Data Quality Method: Fourier-transform infrared spectroscopy (FT-IR) analysis of plastic debris was carried out with a CARY 600 FT-IR (Agilent Technologies) instrument. Measurements were carried out in attenuated total reflectance (ATR) configuration, with a Pike Miracle diamond cell. Tests were carried out at 25 °C in dry air. Particles were identified by comparing FT-IR absorbance spectra of the microplastics to those in a polymer reference library..
