Microplastics in sediments from the  littoral zone of the north Tunisian coast (Mediterranean Sea),

Estuarine, Coastal and Shelf Science, Available online 7 March 2018,  ISSN 0272-7714,

Abstract:

The distribution of microplastics (MPs) was investigated in the  sediments of five sampling sites from the northern Tunisian coast during
June 2017. MPs were categorized according to type, colour and size.

Representative MPs from the five sites were isolated for polymer identification using Fourier Transformed Infrared Spectroscopy in
attenuated total reflectance mode (FTIR-ATR). Results showed that MPs were recovered, from all sediment samples, indicating for the first
time, their extensive distribution in Tunisian coast.
Concentrations varied from 141.20 ± 25.98 to 461.25 ± 29.74 items kg−1 dry weight.

Fibres, fragments, Styrofoam®, pellets and films were the types registered in this study. With the exception of Menzel Bourguiba (MB),
fibres significantly outnumbered plastic particles followed by fragments, Styrofoam®, films and pellets.
The predominant colours are as follows:
black > clear > white > red > blue > green for fibres,
blue > white > clear > red > green > yellow > black for fragments,
blue > white > black > clear for films while only white pellets and Styrofoam® were found.
MPs particles ranged from 0.1 to 5 mm in length.

A total of three polymer types were identified, polyethylene (PE), polypropylene (PP) and polystyrene (PS). Except for industrial pellets,
the presence of MPs is likely due to the degradation of marine plastic debris accumulating in each site. This work provides original data of
the presence of MPs in coastal sediments from Northern Tunisian coast.

(http://www.sciencedirect.com/science/article/pii/S0025326X13006048) Abstract: Plastic debris is often ingested by marine predators and can cause health disorders and even death. We present the first assessment of plastic ingestion in Mediterranean seabirds. We quantified and measured plastics accumulated in the stomach of 171 birds from 9 species accidentally caught by longliners in the western Mediterranean from 2003 to 2010. Cory’s shearwaters (Calonectris diomedea) showed the highest occurrence (94%) and large numbers of small plastic particles per affected bird (on average N = 15.3 ± 24.4 plastics and mass = 23.4 ± 49.6 mg), followed by Yelkouan shearwaters (Puffinus yelkouan, 70%, N = 7.0 ± 7.9, 42.1 ± 100.0 mg), Balearic shearwaters (Puffinus mauretanicus, 70%, N = 3.6 ± 2.9, 5.5 ± 9.7 mg) and the rest of species (below 33%, N = 2.7, 113.6 ± 128.4 mg). Plastic characteristics did not differ between sexes and were not related to the physical condition of the birds. Our results point out the three endemic and threatened shearwater species as being particularly exposed to plastic accumulation.
