Our laboratory supports stormwater monitoring, roadway runoff investigations, aquatic toxicity studies, salmon mortality research, and emerging contaminant projects with sensitive LC-MS/MS analysis and reliable analytical data.

Protecting Aquatic Life Through Advanced Analysis

6-PPD (N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine) is a common tire additive that transforms into 6-PPD-Quinone when exposed to ozone. As tires wear, particles containing 6-PPD and its byproducts enter the environment—eventually washing into streams and rivers through stormwater runoff.

Research has shown that 6-PPD-Quinone is acutely toxic to several fish species, including Coho salmon, brook trout, steelhead/rainbow trout, and Chinook salmon. In Coho salmon, exposure can cause mortality within hours. With its recent discovery, scientists are still uncovering the full environmental impact of this chemical, making accurate monitoring and testing essential.

We provide reliable, high-quality 6-PPD-Quinone testing designed to support environmental monitoring, regulatory compliance, and research.
