Eurofins Environment Testing Australia now offers the targeted analysis of 6-PPD quinone & HMMM by isotope dilution LC-MS/MS in wastewaters and stormwater run-off as well as playground rubber crumb samples. These emerging contaminants have been implicated in what is called Urban Runoff Mortality Syndrome (URMS) that gained notoriety in early 2021 when scientists from University of Washington using high-resolution accurate mass liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QToF-MS) documented tyre additives and their degradants viz 6-PPD and its ozonation product 6-PPD quinone that were responsible for the deaths of Coho salmon (Oncorhynchus kisutch) in Pacific Northwest America.
Classed as emerging contaminants, our Team in Brisbane have developed a method to determine 6-PPD quinone and HMMM at parts per trillion (ppt) levels in surface water, sediments, and rubber crumb widely used in sports fields and playgrounds as well as some multipurpose outdoor activity areas.
