Contamination from microplastics and other anthropogenic particles in the digestive tracts of the commercial species Engraulis encrasicolus and Sardina pilchardus
<p><strong>Dataset of microplastics and other anthropogenic particles found on stomach contents of anchovy and sardines in the gulf of Cadiz (Europe)<br> Dataset with date, longitude and latitude, species, area, sub-area, distance to Guadiana river mouth measured in kilometers (Guadiana), distance to Guadalquivir river mouth measured in kilometers (Guadalquivir), distance to the Bay of Cadiz measured in kilometers (Cadiz), distance to Huelva city measured in kilometers (Huelva), Individual, size (Cm), total weight (g), stomach weight (g), Relative condition index (Kn), Gonadosomatic index (GSI), sex, number of fibres and number of “others anthropogenic particles”.</strong></p> <p><strong>Abstract</strong></p> <p>Fragments of microplastics (< 5mm) found in commercial species of fish, crustaceans, and bivalves, are an issue of global concern. The bioaccumulation of microplastics and other anthropogenic particles in different levels of the food web may provoke unwanted impacts on marine ecosystems and cause pernicious effects on human health. Here, we study the presence of anthropogenic particles and the fraction of microplastics in the target organs of two representative commercial fish species in Spain; the European anchovy (<em>Engraulis encrasicolus</em>) and the European pilchard (<em>Sardina pilchardus</em>). The individuals were sampled along the continental shelf of the Gulf of Cádiz, from the Bay of Cádiz to Cape Santa Maria. The isolation of the microplastics (MPs) was carried out with a complete alkaline-oxidant organic digestion (KOH-H<sub>2</sub>O<sub>2</sub>) of the digestive tract, including both the contents ingested and the muscle tissues. Anthropogenic particles were found in all individuals of both species with an average of 8.94 ± 5.11 items·ind<sup>-1</sup>. Fibres made up 93 % of the items while fragments and films were represented by the remaining 7 %. The average size of the anthropogenic particles was 0.89 ± 0.82 mm. In addition to the fragment and film particles identified as microplastics, 29 % of the fibres were estimated to be microplastics by Fourier-transform infrared spectroscopy (FTIR) analysis. The main polymer found in both species was nylon. No significant correlation was found between the abundance and size of anthropogenic particles ingested and individual size or other body variables. The analysis of similarities (ANOSIM) and the distanced-based multiple linear regression model showed a high homogeneity in anthropogenic particle contamination in both species throughout the study area along the continental shelf of the Gulf of Cádiz.</p>
