Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [1] [2] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [3]
By using data on surface plastic concentration (pieces of plastic per km 2) from 1972 to 1985 (n=60) and 2002–2012 (n=457) within the same plastic accumulation zone, the study found the mean plastic concentration increase between the two sets of data, including a 10-fold increase of 18,160 to 189,800 pieces of plastic per km 2.
You know plastic bottles aren't great for the Earth, but you probably didn't know how bad they are. Plastic bottles make up the second most common ocean pollutant , accounting for 12% of all ...
Plastic resin pellets are classified as primary microplastics, meaning that they were intentionally produced at sizes ranging from 1–5 mm in diameter (whereas secondary microplastics are created through photodegradation and weathering of larger pieces of plastic, like water bottles and fishing nets).
Scientists studying how tiny particles of plastic affect our everyday lives say that the amount of nanoplastics found in bottled water is between 10 to 100 times higher than researchers had ...
Plastic pollution in the ocean 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 which floats on, or is suspended in the ocean.
There are a few potential concerns with plastic water bottles. “One is the plastic bottle itself,” Rumpler says. “There is some evidence to suggest that microplastics are in plastic bottled ...
It is the most significant factor in the weathering of plastics. [2] Photo-oxidation causes the polymer chains to break (chain scission), resulting in the material becoming increasingly brittle. This leads to mechanical failure and, at an advanced stage, the formation of microplastics.
