Initially, my research sought to investigate the biodegradation of 6PPD and 6PPD-quinone using microbial cultures. However, unexpected challenges arising from limited solubility and potential toxicity to microorganisms led to a shift in research objectives. The study then refocused on developing methods for detecting and quantifying 6PPD and 6PPD-quinone. The scarcity of literature available on the environmental fate and transport of these compounds underscores the pressing need for further research to gain a comprehensive understanding of the behavior of these chemicals. Consequently, the development of effective detection strategies will enable the development of effective remediation strategies to safeguard aquatic ecosystems. 6PPD 6PPD-quinone Biodegradation The Detection and Quantification of Tire Derived Chemicals, 6PPD and 6PPD-quinone
