You probably haven’t given a lot of thought to the damaging effects of tire wear, at least when it comes to our food supply. But a study out of the University of Vienna (UV) will likely change your perspective on that.  With concern for at least five known toxins in tire wear products (TWPs), researchers grew lettuce in a hydroponic system, adding TWPs to the water to measure the effect. They found the chemicals traveled up to the edible leaves of the plants . Although the toxicity of some of the pollutants tested are unknown, there’s strong evidence measuring the link between a compound known as 6PPD-quinone and mass salmon deaths. As evidenced in a study reported in Science , even a small exposure to 6PPD-quinone killed Coho salmon in the lab environment.…
