High Concentrations of Plastic Hidden Beneath the Surface of the Atlantic Ocean

ِDo you know…

Concern over plastic pollution of the marine environment is severe. The ocean interior conceals high loads of small-sized plastic debris which can balance and even exceed the estimated plastic inputs into the ocean since 1950.

The combined mass of just the three most-littered plastics (polyethylene, polypropylene, and polystyrene) of 32–651 µm size-class suspended in the top 200 m of the Atlantic Ocean is 11.6–21.1 Million Tonnes. Considering that plastics of other sizes and polymer types will be found in the deeper ocean, results obtained in 2020 indicate that both inputs and stocks of ocean plastics are much higher than determined previously.
