Primary question. What process or criteria should be used for identification and prioritization of CECs … International perspective for chemical regulation (REACh), Great Lakes prioritization – IJC, USGS etc Other reviews and prioritizations; can we use national and int’l priority lists?
MOA can be used to priortize
Pesticides could be replaced but could be viewed as a success story
Bioaccumulation of pharmas important for prioritizing
Hormone receptor binding
List should vary with type of application
Limit to capacity to measure i.e. cost, number of methods,
Centralization of analytical capacity especially for new, difficult to analyse compounds
Removal effectiveness could be a criterion – poorly removed compounds could be a priority
Have a list based on effects, bioaccumulation, - then consider degradation, removal
Ocean outfalls – difference from freshwater emissions
Conceptual models of the exposure useful
Or should we select just a few winners?
