“…Furthermore, they may also form during household cooking processes when using chloraminated tap water and iodized salt 27 . A number of low-and high-molecular weight I-DBPs have been identified in recent years 3,5,29,[35][36][37][38][39][40] , and their formation is influenced by a variety of factors, including the levels of iodide present in source waters [41][42] , molecular size of NOM 43 , presence of microbial organic matter 44 , and the presence of other iodine sources, such as iodinated X-ray contrast media (ICM) [45][46] . ICM are commonly administered for medical imaging of soft tissues; they are administered in high doses (up to 200 g/person/day), excreted mostly unchanged, and poorly removed in wastewater treatment plants.…”
