Million tons of Microplastic pollution in the Atlantic Ocean
Part of: GS-Prelims and GS-III – Environment
- A study was published in ‘Nature Communications’ about micro plastic pollution in the Atlantic Ocean.
- The pollution is put at 11.6-21.1 million tonnes.
- Top 200 meters of the Atlantic was measured.
- Pollution caused by three types of plastics was studied – polyethylene, polypropylene, and polystyrene.
- These are most commonly used for packaging.
- Both inputs and stocks of ocean plastics may be much higher than determined.
- Assessment across all sizes and polymer groups is important to determine the danger of plastic pollution.
Important value additions
- It is a synthetic organic polymer made from petroleum.
- Building and construction
- Household and sports equipment
- It is cheap, lightweight, strong and malleable.
- Sources of Marine Plastic:
- Land-based and storm runoff
- Sewer overflows
- Beach visitors
- Inadequate waste disposal
- Impact of Plastic Pollution
- Ingestion, suffocation and entanglement of hundreds of marine species.
- The transfer of contaminants between marine species and humans through seafood consumption.
- Contribution to global warming
