New USEPA SW-846 Method 4435 for HAH Analysis.

摘要

Accurate identification and quantitation of dioxin-like halogenated aromatic hydrocarbons (HAHs) in environmental matrices are critical for site assessment, risk assessment, and environmental monitoring. Although sophisticated cleanup and instrumental analytic procedures are available to separate, identify, and quantitate individual HAHs, these procedures require specialized equipment and are both costly and time-consuming. A US Environmental Protection Agency (EPA) Superfund Innovative Technology Evaluation (SITE) report states that the gas chromatograph/mass spectrometer (GC/MS) analysis of 209 demonstration samples cost approximately $1100 per sample and took approximately 8 months.
