Photodegradation is the process by which materials break down when exposed to sunlight, particularly ultraviolet (UV) radiation. This phenomenon affects various substances, including plastics, dyes, and organic compounds, leading to changes in their chemical structure and properties. As a result, photodegradation can contribute to environmental pollution and the degradation of ecosystems. During photodegradation, the energy from sunlight can cause chemical bonds within a material to weaken or break. This process can lead to the formation of smaller, often more toxic, byproducts. Understanding photodegradation is essential for developing more sustainable materials and improving waste management practices, especially concerning plastic pollution and environmental conservation.
