Urban Signature Pesticides (USPs)

A new USGS study reports that, of 108 pesticides analyzed, 16 dissolved pesticides were consistently detected in at least 13 of 16 urban centers studied (>80%), and in all 5 of the 5 major regions studied across the U.S. This study proposes that these 16 pesticides comprise a suite of “urban signature pesticides” (USPs) common in small U.S. urban streams.
