Dr. Tianxi Yang and his team have created a small, portable device that can accurately measure microplastics in water samples within minutes. The innovative tool consists of a 3D-printed box ...
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
Marine plastic pollution. The pathway by which plastics enters the world's oceans. Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish ...
Plastics accounts for 80% of waste dispersed in the marine and coastal environment of the Mediterranean Sea. [24] Recent studies focus on the types of plastics found and primarily on the issue of microplastics, both at a global but also at a regional level, as in the case of the Mediterranean Sea, which was identified as a "target hotspot of the world" due to its amounts of microplastics ...
Visible on deck are the three distinctive shark-fin domes of the PUFFS sonar. The Greater Underwater Propulsion Power Program (GUPPY) was initiated by the United States Navy after World War II to improve the submerged speed, maneuverability, and endurance of its submarines. (The "Y" in the acronym was added for pronounceability.)
More recent research has found that typical water bottles have far higher levels: 240,000 particles per liter on average, taking into account smaller fragments known as "nanoplastics." The ...
One recent study showed that exposure to microplastics through drinking water over the course of three weeks caused cognitive changes in mouse brains. The particles were also able to cross the ...
The plastisphere is a human-made ecosystem consisting of organisms able to live on plastic waste. Plastic marine debris, most notably microplastics, accumulates in aquatic environments and serves as a habitat for various types of microorganisms, including bacteria and fungi. [1][2] As of 2022, an estimated 51 trillion microplastics are floating ...
