Deciphering Cadmium’s Impact on Biodegradation of Triphenyl Phosphate in Sediments



A new study is shedding light on how cadmium contamination influences the biodegradation of triphenyl phosphate (TPHP)—a widely used organophosphate flame retardant—within sedimentary environments. Using a combination of molecular biology tools and computational chemistry techniques, researchers have uncovered the complex interactions between heavy metals and microbial degradation pathways.

The findings reveal that cadmium not only disrupts microbial community structures but also alters the enzymatic activities essential for breaking down TPHP. Computational models further demonstrated how cadmium ions interfere with enzyme active sites, thereby slowing the degradation process. These insights are critical, as TPHP is increasingly detected in aquatic ecosystems, posing risks to both environmental and human health.

By integrating multi-scale biological analysis with molecular simulations, the study provides a comprehensive framework for understanding pollutant dynamics in contaminated sediments. Experts believe this research could guide the development of more effective bioremediation strategies and policies to mitigate the dual threat of toxic heavy metals and persistent organic pollutants.
