E not in accordance with one another. Because the HQ is usually a function of two things, i.e., PEC and toxicity, this discordance could arise from either or both in the two components. It was noted that the ranking by PEC tends to comply with that by emission, indicating that the emission price dictates the PEC of those 19 pharmaceuticals in water. Consequently, the discordance between the rankings by emission and by HQ ought to largely be accounted for by the toxicity with the pharmaceuticals. These 19 pharmaceuticals can be divided into three groups from a management perspective. The initial group incorporates pharmaceuticals of high HQ ranking as a consequence of higher emission (e.g., cimetidine, roxithromycin, and amoxicillin). For this group, the management focus must be placed on emission reductionmeasures, such as usage manage or Takeback applications The second group is the fact that of high HQ ranking mostly on account of higher toxicity in spite of emission not being as high (e.g., acetaminophen, trimethoprim, and erythromycin). The use or improvement of less or nontoxic alternatives could be a option if emission is already low. The third is the group of pharmaceuticals of medium to low HQ ranking for which the want of monitoring, as the first step of further management action, ought to be determined depending on the level of the respective HQ. Extra facts on the management approaches for every in the three groups are presented in ESM 3. To summarize, we have created an emission estimation model covering the pathways of pharmaceuticals, including the provide chain, patient administration and individual handling, and many treatment and disposal processes. Primarily based on the uncertainty and sensitivity assessments, we have not just identified one of the most influencing parameters/variables but have also drawn their management implications. The model estimates, as assessed employing PECs, had been in agreement with measured values using a disparity less than one particular order of magnitude. We’ve demonstrated that the model may well potentially be applied for the purposes of estimating the emission prices to surface waters and identifying elements crucial to lowering these emission prices, at the same time as be applied for the screening and priority setting of pharmaceuticals.17288-36-7 web Acknowledgments This study was funded by KEITI, NRF, and KEI below study grants with contract numbers 412111003, 20110016767, and 2013063, respectively.
