Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Scientific literature confirms that exposure of ABS plastic to ultraviolet radiation induces photo-oxidation, leading to chemical degradation and discoloration.

The analysis

The retrieved papers document the photo-oxidation and degradation of acrylonitrile butadiene styrene (ABS) under UV radiation. Papers [1] and [7] specifically analyze the photo-oxidation mechanisms of ABS upon UV exposure, aligning directly with the claim. No papers dispute the mechanism.
