We can see that while the fluorescence intensity of the polluant is modified in the presence of DOM (DOC), its lifetime does not change. Thus, we have static quenching. Dissolved organic matter-hydrophobic polluant interactions are pH-dependent. In fact, DOC are acids, and so at high pHs, their structure could be modified, and their interaction with hydrophobic polluant would decrease.
