Accurate, reliable, and regulatory-compliant air sampling and analysis of dioxins and furans. 

METS Lab offers specialized testing services for Dioxins and Furans in ambient and process air using internationally recognized sampling and analytical techniques. Our services help industries, government agencies, and environmental consultants monitor ultra-trace levels of these highly toxic compounds, ensuring compliance with national and international environmental regulations. 

What Are Dioxins and Furans? 

Dioxins (polychlorinated dibenzo-p-dioxins, or PCDDs) and furans (polychlorinated dibenzofurans, or PCDFs) are persistent organic pollutants (POPs) formed as unintentional by-products of industrial processes involving combustion, especially those involving chlorine-containing materials. These include: 

• Waste incineration (municipal, biomedical, hazardous) 

• Cement kilns burning alternative fuels 

• Metallurgical industries (e.g., secondary copper, aluminum, and steel production) 

• Chemical manufacturing 

Even at extremely low concentrations, dioxins and furans are harmful, with long-term exposure linked to cancer, reproductive disorders, immune suppression, and endocrine disruption. 

Our Testing Capabilities 

At METS Lab, we conduct sampling and analysis of dioxins and furans in air using methods designed to detect concentrations in picograms per cubic meter (pg/Nm³). Our lab uses High-Resolution Gas Chromatography–High-Resolution Mass Spectrometry (HRGC-HRMS) for precise and legally defensible quantification. 

Our Services Include: 

• Isokinetic stack sampling of dioxins and furans as per CPCB and USEPA Method 23 

• Ambient air sampling using high-volume samplers and polyurethane foam (PUF) cartridges 

• Laboratory analysis following international QA/QC protocols 

• Reporting of individual congeners and Toxic Equivalents (TEQ) 

• Support with emissions permit applications and compliance documentation
