Critical role of natural organic matter in photodegradation of methylmercury in water: Molecular weight and interactive effects with other environmental factors
NOM can significantly inhibit the Fe3 +-induced degradation of MeHg. High molecular weight NOM shows higher light attenuation-induced degradation inhibition. Photodegradation-mediated by NOM is also affected by pH and co-existing Cl− and NO3−.
