Microplastics are an increasingly common threat to the aquatic environment, and, due their small size, it is easy for them spread and enter seas oceans. Micro- mesoplastic particles often ingested by marine organisms, especially those that have potential successful settlement on artificial substrata, including plastic. In laboratory experiments, we tested tendency of sea anemone Exaiptasia diaphana consume plastic fragments fibers various sizes shapes; these organisms widely distributed in coastal waters, tide pools, coral reefs. The were placed either natural food or covered with a special gel form, which allowed retain original shape. Our studies shown shape less readily consumed than form fragments. E. anemones oral discs diameter 10–12 mm had difficulty consuming long fibers. A total 67% studied animals unable 13 length, while 3 7 length 100% anemones. We also established microplastics taken harmful cnidarians: mechanical injury body column was caused polypropylene microfragments, observed significantly increased mortality. Injuries, combined possible toxicological effects polymers, may been cause mortality diaphana.

Marine microplastics are a global environmental issue, and understanding their distributions in estuaries coastal areas is critical prerequisite for the effective sustainable management of microplastic pollution. Owing to lack methods that exist quantifying content, characterizing distribution difficult. The mass concentration an objective indicator reflects distribution. Therefore, formula calculating proposed through parameters number concentration, size, mesh addition proportions particles with different sizes shapes. On basis large amount existing measured data, concentrations calculated. It can be concluded polypropylene (PP; 72%) polyethylene (PE; 67%) most abundant ocean. Additionally, marine more common (102–103 mg/L) than open sea (0–10 mg/L). maximum surface water approximately 8.0 g/L. Moreover, pollution has significantly increased surrounding sewage treatment plants aquaculture farms.
