طريقة QuEChERS-HPLC المعدلة للكشف عن الهيدروكربونات العطرية متعددة الحلقات في أجنة أسماك الزرد المعرضة للجسيمات الدقيقة

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.
