Executive Industry Relevance

Quantitative detection of polycyclic aromatic hydrocarbons (PAHs) in small, complex biological matrices is a critical challenge in early toxicology and environmental risk assessment workflows. The modified QuEChERS-HPLC method enables sensitive, reproducible measurement of internal PAH levels in zebrafish embryos, supporting mechanistic de-risking and predictive confidence in developmental toxicity studies. This capability strengthens translational continuity from environmental exposure models to preclinical safety evaluation in biopharma pipelines.
