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.
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.

A plastic bucket used as an open-air flowerpot photodegraded after some years. Photodegradation is the alteration of materials by light. Commonly, the term is used loosely to refer to the combined action of sunlight and air, which cause oxidation and hydrolysis. Often photodegradation is intentionally avoided, since it destroys paintings and ...
According to the directive, there is a ban on plastic cotton buds and balloon sticks, plastic plates, cutlery, stirrers and straws, Styrofoam drinks and food packaging (e.g. disposable cups and one-person meals), products made of oxo-degradable plastic, which degrade into microplastics, while cigarette filters, drinking cups, wet wipes ...
Studies have shown that drinking water from plastic bottles has significantly greater detectable plastic content than tap water. [ 40 ] These findings suggest that breastfeeding may inadvertently expose infants to endocrine-disrupting plastics, which could have lasting effects on growth and development.
