Approximately 2% of the plastics in the ocean may dissolve due to the ultraviolet (UV) light from the sun. This is according to a recent study published in the journal Environmental Science & Technology.
The study found that certain types of plastic, such as polyethylene and polypropylene, are particularly susceptible to dissolution by UV light. These types of plastic are commonly found in products such as plastic bags, bottles, and packaging materials.
When plastics dissolve, they break down into smaller particles known as microplastics. These microplastics can be harmful to marine life and the ecosystem, as they can be ingested by organisms and enter the food chain.
The study also found that the dissolution of plastic in the ocean may be accelerated by other environmental factors, such as the presence of salt and organic matter. The researchers note that more studies are needed to fully understand the potential impact of these factors on the dissolution of plastic in the ocean.
The findings of this study highlight the urgent need for effective solutions to the plastic pollution problem. This includes reducing the amount of plastic produced and used, as well as finding ways to properly dispose of or recycle plastic waste.
In addition, the study also stresses the need for research to identify the most effective ways to remove plastic from the ocean and prevent it from causing further harm to marine life and the environment.
It is important to note that plastic pollution is a global problem that requires a global solution. All countries must work together to reduce the amount of plastic produced and used, as well as to properly dispose of or recycle plastic waste.
In conclusion, while sunlight may not be the most significant cause of plastic dissolving in the ocean, this study shows that it plays a role and highlights the need for continued research and actions to address plastic pollution and its impact on our oceans.
