New! SGS AXYS is pleased to measure the major antiozonant degradation product 6-PPD Quinone and its parent compound 6-PPD at sub ng/L reporting limits.
Although antiozonants are widely used to prevent damage to elastomers, recent findings reveal they also have the ability to cause environmental damage with 6-PPD quinone raising alarms worldwide. 6-PPD is an oxidation control substance added to rubber tires as an antiozonant which oxidizes to the 6-PPD quinone in the environment. As we drive our busses, cars and spin our tires, the runoff from this tire wear enters streams and other bodies of water. Ultimately, this quinone has proven very toxic to Coho Salmon in urban streams. Unfortunately, juvenile salmon are extremely susceptible to this environmental concern.
Antiozonants are substances that prevent or delay the degradation of material as a result of attack by ozone.
6-PPD is an antiozonant, with widespread use in the rubber industry, 6-PPD Quinone is a toxic degradation product of 6-PPD.
Coho Salmon, one of the five Pacific salmon species, are currently listed under the U.S. Endangered Species Act (ESA) and risk extinction.
Once again, SGS AXYS has put its scientific expertise to use in developing the first method that quantifies 6-PPD quinone together with its precursor compound, 6-PPD. Quantification of 6-PPD, a very unstable analyte, is made possible with the use of selected reducing agents that stabilize the compound during sample storage, extraction, and analysis.
Antiozonants are often reactive and unstable, they react with atmospheric ozone, oxygen and the reactions are facilitated by both heat and light. Using best practices, SGS’s unique method measures the major antiozonant degradation product 6-PPD Quinone and its parent compound 6-PPD at sub ng/L reporting limits. While testing for the 6-PPD quinone is essential, SGS takes it one step further by analyzing for the precursor compound to provide additional value.
The fight to proactively sustain our ecology and biodiversity for future generations is now more important than ever. SGS AXYS targets the impacts of aquatic environments affected by surface run-off advocating for the long-term viability of our ecosystems.
SGS AXYS is developing a method that covers a wide range of diphenylamine based antiozonants, phenolic antioxidants and benzotriazole and benzophenone light protectants as well as selected degradation products that are a concern in road run-off and other sources. This method will allow us to conduct a comprehensive monitoring of oxidation control substance.
