Main Question or Discussion Point
I have been searching on Google about UV degradation of plastics , polypropylene in particular. I understand fully that it will break the plastics and so many plastics / polypropylene are not suitable for usage under sunlight. I also found that on the molecular level the sunlight will break the bond and release free radicals. However, I can hardly find any information about what would be the end --products of the UV degradation of plastics. Is the end-product released into the air bad for human? I have a lot of PP containers which are so big in size and they are often stressed under sunlight in daytime in a small room which is not very well ventilated. Would this accumulate some gaseous plastics circulating around the room or other unhealthy chemicals ?
