TL;DR: This study indicates that similarly structured antibiotics will be subject to a wide range of photodegradation rates with sulfathiazole degrading relatively quickly, sulfisoxazole and sulfamethizole degrading moderately, and sulfanilic acid degrading much more slowly.

TL;DR: In this article, the aqueous photochemistry of four pharmaceutical compounds detected in surface waters (naproxen, diclofenac, ibuprofen, and clofibric acid) was investigated in purified (Milli-Q) water and in Mississippi River water (MRW).

TL;DR: A review with 310 references summarizes the current knowledge of the photochemical behavior of pharmaceuticals and highlights the use of the fundamental photochemistry and phototoxicity literature to help understand and predict the aquatic fate of pharmaceutical drugs.

TL;DR: It is proposed that through the use of appropriate sets of probe compounds and model photosensitizers an improved estimation of the distribution of triplet energies and one-electron reduction potentials of 3CDOM* can be achieved.

TL;DR: Photodegradation of the sulfa drugs in a natural water sample was significantly enhanced relative to the degradation in deionized water, with the exception of sulfadimethoxine, which indicated an indirect photochemical process that was identified through the use of quenchers to be attributable to interaction with triplet excited-state dissolved organic matter (3DOM).
