ASTM D6238 Dioxins and Furans in Environmental Samples Test
The ASTM D6238 standard provides a precise methodology for determining the concentration of dioxins and furans (PCDD/Fs) in environmental samples. This test is crucial for ensuring that industrial processes, waste management practices, and other activities do not release harmful levels of these potent toxins into the environment.
Dioxins and furans are a group of highly toxic compounds known as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans. These chemicals are unintentional by-products of various industrial processes, including waste incineration, metal production, and chemical manufacturing. Once released into the environment, they can persist for long periods, bioaccumulate in the food chain, and pose significant health risks to humans and wildlife.
Given their persistence and toxicity, it is critical to monitor dioxin levels in air, water, soil, and biota. The ASTM D6238 test aims to identify these compounds accurately and quantitatively through a series of complex analytical procedures that ensure reliable results.
The testing process involves several key steps:
- Sample collection: Environmental samples such as air filters, water samples, or soil extracts are collected from potential sources of dioxins and furans.
- Extraction: The extracted compounds are purified using solvent-based methods.
- Analysis: High-resolution gas chromatography coupled with mass spectrometry (HRGC-MS) is used to analyze the extracted compounds for their presence and concentration.
The ASTM D6238 test ensures that results are accurate and reproducible, adhering to international standards such as ISO 15267. Compliance with these standards guarantees that the testing process meets rigorous quality control criteria.

Scope and Methodology
The ASTM D6238 test focuses on the determination of 17 specific congeners of dioxins and furans in various matrices such as air, water, soil, and biota. This standard is particularly important for ensuring compliance with environmental regulations set by governmental bodies like EPA (United States Environmental Protection Agency), WHO (World Health Organization), and other international organizations.
The scope includes the extraction of dioxins and furans from complex matrices using solvent-based methods such as Soxhlet or ultrasonic extraction. The extracted compounds are then purified and concentrated prior to analysis by HRGC-MS. This analytical technique allows for highly sensitive detection and quantification of even trace amounts of these pollutants.
| Sample Matrix | Dioxin Congeners |
|---|---|
| Air Filters | All 17 congeners of dioxins and furans. |
| Water Samples | All 17 congeners of dioxins and furans. |
| Soil Samples | All 17 congeners of dioxins and furans. |
| Biota | Selective analysis based on matrix-specific requirements. |
The methodology also includes detailed instructions for sample preparation, extraction efficiency checks, and quality control measures. These steps ensure that the results are accurate, reliable, and reproducible across different laboratories and analysts.
