Article Synopsis
- Plastic pollution is a growing global issue, making it essential to study how biofilms form and behave on plastic materials in marine environments.
- Research in the Black Sea examined how biofouling on PET plastic fragments varies seasonally and vertically, with findings indicating less biofouling in surface waters compared to deeper layers and peaks in summer.
- The study suggests using the green alga Phycopeltis arundinacea as a bioindicator to determine the age of biofouling communities, ultimately helping monitor the longevity and degradation of plastic debris in oceans.
Twelve seas with an integral coastline length of about 38,000 km wash upon the Russian coasts. They belong to the basins of the Atlantic, the Arctic, and the Pacific Oceans and stretch over temperate, subpolar, and polar climate zones. This review of 32 studies published between 2015 and August 2020 analyses the available peer-reviewed scientific publications related to the topic of plastic contamination.

This is the first attempt to comprehend the ecological risk of MPs in sediments along the Indian coast using meta-data. Polymer hazard index (PHI), pollution load index (PLI) and potential ecological risk index (PERI) were used to evaluate the quality of sediments.

Macro-samples were prepared from brittle not-buoyant PS (disposable plates), flexible thin film of LDPE (garbage bags), highly buoyant foamed PS (building insulation sheets), and hard buoyant PP (single-use beverage cups). With a great variety of behaviors of plastics while mixing, coarser sediments (pebbles) have higher fragmentation efficiency than sands (measured as the mass of generated MPs), disregarding sinking/floating or mechanical properties of the samples.
