This plastic bucket has been used as an open-air flowerpot for some years. Photodegradation has made it brittle, causing part of it to break off when the bucket was moved. In polymer chemistry, photo-oxidation (sometimes: oxidative photodegradation) is the degradation of a polymer surface due to the combined action of light and oxygen. [1]
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 which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic.
A plastic bucket used as an open-air flowerpot photodegraded after some years. Photodegradation is the alteration of materials by light.

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).
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.
