Secondary microplastics formation and colonized microorganisms on the surface of conventional and degradable plastic granules during long-term UV aging in various environmental media.

Journal of Hazardous Materials, 2022
Recently, biodegradable plastics (BPs) as an alternative of conventional plastics have been widely advocated and applied. However, there is still a large research gap between the formation of secondary microplastics (MPs) and colonized microorganisms on ...

UV aging of microplastic polymers promotes their chemical transformation and byproduct formation upon chlorination.

Science of the Total Environment, 2022
The presence and accumulation of microplastics (MPs) in water and wastewater is a growing concern. When released to the water bodies, microplastics can be subject to surface weathering due to ultraviolet (UV) exposure.

UV light and skin aging

Reviews on Environmental Health, 2014
This article reviews current data about the relationship between sun radiation and skin, especially with regards ultraviolet light and the skin aging process. The benefits of sun exposition and the photoaging process are discussed. Finally, the authors present a review of photoprotection agents that are commercially available nowadays.

UV aging of fluorescent reflectors

Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 2002
Tests were carried out to investigate the rate of deterioration of fluorescent reflector materials under high irradiance of UV-C radiation. The results show a wide range of aging rate with different materials, some of which may be unacceptable in service.

UV-induced microplastics (MPs) aging leads to comprehensive toxicity

Marine Pollution Bulletin, 2023
Herein, the toxicity of 4 MPs and additives released from MPs during UV-aging was quantitatively evaluated by the transcriptional effect level index (TELI) based on E. coli whole-cell microarray assay, and MPs-antibiotics complex pollutants. Results showed that MPs and these additives had high toxicity potential, the maximum TELI was 5.68/6.85 for ...

Combined machine learning–wave propagation approach for monitoring timber mechanical properties under UV aging

, 2021
This study proposes a combined machine learning–wave propagation approach for nondestructive prediction of the modulus of elasticity (MOE) and rupture (MOR) of timber subjected to ultraviolet (UV) radiation.

UV-light-induced signal cascades and skin aging

Ageing Research Reviews, 2002
UV irradiation acts as a broad activator of cell surface growth factor and cytokine receptors. This ligand-independent receptor activation induces multiple downstream signaling pathways that regulate expression of multiple genes. These signaling pathways converge to stimulate transcription factor AP-1.
