Plastic pollution on the Baltic beaches of Kaliningrad region, Russia
AI summary Read the abstract
Researchers surveyed microplastic contamination on Baltic Sea beaches in Russia's Kaliningrad region between 2015 and 2016, finding 1.3 to 36.3 items per kg dry sediment with foamed plastic predominating, and detecting no clear difference in contamination levels between high- and low-traffic beach sites.
Contamination of sandy beaches of the Baltic Sea in Kaliningrad region is evaluated on the base of surveys carried out from June 2015 to January 2016. Quantity of macro/meso/microplastic objects in the upper 2cm of the sandy sediments of the wrack zone at 13 sampling sites all along the Russian coast is reported. Occurrence of paraffin and amber pieces at the same sites is pointed out. Special attention is paid to microplastics (range 0.5-5mm): its content ranges between 1.3 and 36.3 items per kg dry sediment. The prevailing found type is foamed plastic. No sound differences in contamination are discovered between beaches with high and low anthropogenic load. Mean level of contamination is of the same order of magnitude as has been reported by other authors for the Baltic Sea beaches.

Microplastic concentrations in beach sediments along the German Baltic coast
AI summary Read the abstract
Researchers measured microplastic contamination on beaches along the German Baltic coast near river estuaries and tracked seasonal variation over several months, finding contamination at all sites. The study highlights that river mouths are hotspots for microplastic deposition on coastal beaches.
Microplastic contamination of sandy beaches of national parks, protected and recreational areas in southern parts of the Baltic Sea
AI summary Read the abstract
Researchers found microplastic contamination in all 51 surface beach sand samples across seven sites along the southern Baltic Sea, including national park and protected areas, at a mean of 68 items/kg dry weight. Expanded polystyrene fragments were the most common type (~38%), and protected areas did not differ substantially from recreational beaches.
