While traces of pharmaceuticals have been found as environmental =
contaminants, I've never seen estimates  of the relative contributions =
of various possible sources:

Consumer unused drug discards
Consumed but under-metabolized drugs passing into wastewater
Agricultural sources
Industrial sources

Is anyone aware of any work done to come up wit an estimate?
