Assessing polycyclic aromatic hydrocarbons (PAHs) in contaminated soils goes far beyond reporting concentrations. The real value lies in understanding what those concentrations mean for ecosystems and human health.
Here are two methodology infographics covering:
• Ecological Risk Assessment of PAHs in Dump Site Soils • Risk Quotient (RQ) approach • Toxic Equivalency (BaPTEQ & BaPMEQ) • Ecological risk classification and interpretation • Assessment of all 16 EPA priority PAHs
• Human Health Risk Assessment of PAHs in Dump Site Soils • Ingestion and dermal exposure pathways • Chronic Daily Intake (CDI) • Hazard Quotient (HQ) & Hazard Index (HI) • Incremental Lifetime Cancer Risk (ILCR) • Total Cancer Risk (TCR) • Child and adult exposure scenarios based on internationally accepted guidelines
•
My objective is to transform complex environmental risk assessment methodologies into clear, publication-quality visuals that can support researchers, students, environmental consultants, and decision-makers.
Scientific research should not only be accurate, it should also be easy to understand, reproduce, and communicate.
