Seasonal and diurnal occurrence of N-nitrosamines and their formation potentials in Yodo River Basin

摘要

NDMA, NMOR and NPYR were majorly detected among targeted NAs in the study area in the Yodo River Basin, although natural attenuation of NDMA would occur along rivers, influenced by seasonal and diurnal change. NMOR mainly came from STPs. FPs of NDMA and NPYR were detected in the most downstream site in this study, where upstream of uptake point for drinking water. Both monitoring of NAs and FP test were needed for the water quality management in a river basin.
