PPRTV Comparison

In order to identify PPRTVs (values not assessments), scroll down until your contaminant or contaminants of interest are visible in the drop down menu under "Select Chemicals to Compare", and highlight the contaminant names by left clicking on the contaminant name(s) while scrolling down. Then, check the types of toxicity values (e.g. subchronic Reference Doses and oral slope factors) of interest under "Select type of data to compare (check all that apply)", and then hit submit. This will generate a file which comes up on your screen, which may also be printed. Users should note that this feature only identifies PPRTVs and will not identify IRIS values, which EPA provides in a separate database.
