Recent findings that 2-anilo-5-[(4-methylpentan-2-yl)amino]cyclohexa-2,5-diene-1,4-dione (6PPD-quinone), the transformation product of a common tire rubber antioxidant, is acutely toxic in stormwater-impacted streams has highlighted need for better understanding contaminants urban runoff. This study represents one first reports 6PPD-quinone and other rubber-derived compounds stormwater snowmelt...

Although the typical antioxidant, N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), ensures high durability and long lifespan for rubber compounds, it generates a highly toxic quinone in water, causing serious environmental pollution. Herein, as an alternative material of 6PPD, we newly introduce eco-friendly amine-functionalized lignin (AL) to be incorporated rubber, which can provide...

The tire wear transformation product 6PPD-quinone (6PPDQ) has been implicated as the causative factor for broad scale mortality events coho salmon in Pacific Northwest. Highly variable sensitivity to 6PPDQ closely related salmonids complicates efforts evaluate broader toxicological impacts aquatic ecosystems. Our goals were (1) validate large range of vivo species sensitivities reported coho, C...

Abstract Many industrial applications require natural rubber (NR) as an irreplaceable polymer for its unique behaviour resistance to crack growth. The damage caused by ozone, seen ageing accelerator, influences the lifetime of components. data on ozone-induced experiments are often incomplete or remain unpublished, whereas comprehensive databases other environmental loads oxygen do exist. A var...

Plastics are commonly synthetic polymers used by many industries because they inexpensive, durable, moldable, and have a wide range of applications. However, plastics production, use, waste associated with numerous challenges, including unsustainable resource greenhouse gas emissions, toxic chemicals, unprecedented environmental pollution. Here, we provide an overview plastic end life, highligh...
