Ecotoxicity of 6PPD and 6PPD-Q in aquatic ecosystems: Mechanisms, influencing factors, and mitigation strategies

Journal of Hazardous Materials
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its oxidation product 6PPD-quinone (6PPD-Q) are widely present in the environment due to their extensive use in rubber products, especially tires. Once released, 6PPD undergoes transformation to 6PPD-Q, which has been detected in air, dust, sediments, surface waters, and wastewater ...

Exploring a green-approach for 6PPD and 6PPD-Q removal: Riverine plants in natural wetlands

Journal of Hazardous Materials
The tire-derived antioxidant 6PPD and its highly toxic transformation product (TP) 6PPD-Q represent an emerging threat to aquatic ecosystems. For example, 6PPD-Q is identified as the cause of acute mortality in coho salmon. This study investigates the phytoremediation potential of riverine plants in natural wetlands (e.g. Typha minima (T.

Occurrence, Transformation, and Toxicity of Tire-Derived Chemicals 6PPD and 6PPD-q in the Environment

Environmental Science & Technology
6PPD (N1-(4-methylpentan-2-yl)-N4-phenylbenzene-1,4-diamine), a widely used rubber antioxidant in tire manufacturing, has garnered increasing global attention, following the discovery that its ozone-oxidation product, 6PPD-q, is the primary toxicant responsible for urban runoff mortality syndrome (URMS) in salmon.

Insights into the impact of 6PPD-Q and 6PPD on nitrogen metabolism and microbial community in the anammox system

Environmental Research
N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) is an antioxidant commonly used in tire manufacturing, and its release into the environment has significantly increased due to rapid urbanization. When subjected to ozonation, 6PPD converts into the harmful pollutant 6PPD quinone (6PPDQ). These substances enter wastewater treatment plants (WWTPs)

6PPD-Q driven rare and abundant taxa functional partitioning shapes soil ecological response

Journal of Hazardous Materials
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), a toxic transformation product of tire antioxidants, may pose ecological risks to soil ecosystems due to its persistence and strong adsorption. However, its degradation mechanisms and ecological impacts in soil remain poorly understood. Here, we conducted a 49-day microcosm experiment

Foliar exposure to 6PPD-Q disturbs photosynthetic processes and induces oxidative stress in Eichhornia crassipes

Journal of Environmental Management
Air pollution is a currently common global concern issue. The widespread occurrence of N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), a transformation product of tire additives detected on airborne particular matter, necessitates an urgent assessment of its environmental risks.

Developing water quality criteria and assessing ecological risks for 6PPD and 6PPD-Q in freshwater ecosystems

Environmental Pollution
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its derivative N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), originating from tire wear particles (TWPs), are emerging contaminants (ECs) of growing concern. This study focused on the development of water quality criteria (WQC) for 6PPD and 6PPD-Q in freshwater ...

Tire rubber derivative 6PPD and 6PPD-Q induce lipid accumulation in hepatocytes through ERRγ pathway

Journal of Environmental Sciences
N-phenyl-N'-(1,3-dimethylbutyl)-p-phenylenediamine (6PPD) is a tire rubber antioxidant that can be oxidized to form derivative 6PPD-quinone (6PPD-Q). 6PPD and 6PPD-Q have been detected in human urine with concentrations reaching nanomolar levels. However, their human adverse effects and toxic mechanisms are not explicit.
