“…The process of light-dependent transformation is influenced by factors such as the presence of dissolved organic matter in the environment, microbial content, varying pH, season, and depth. Compared to ultrapure water, most often in the environment, due to the content of dissolved organic matter, faster phototransformation processes are observed [11][12][13][14]. The toxicity of phototransformation products may turn out to be reduced or increased in relation to the parent substance.…”
