Soil, treated biowaste and sludge - Determination of dioxins and furans and dioxin-like polychlorinated biphenyls by gas chromatography with high resolution mass selective detection (HR GC-MS)
This draft European Standard specifies a method for quantitative determination of 17 2,3,7,8-chlorine substituted dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls in sludge, treated biowaste and soil using liquid column chromatographic clean-up methods and GC/HRMS.
The analytes to be determined with this European Standard are listed in Table 1.
(...)
The limit of detection depends on the kind of sample, the congener, the equipment used and the quality of chemicals used for extraction and clean-up. Under the conditions specified in this European Standard, limits of detection better than 1 ng/kg (expressed as dry matter) can be achieved.
This method is "performance based". It is allowed to modify the method if all performance criteria given in this method are met.
NOTE In principle this method can also be applied for sediments, mineral wastes and for vegetation. It is the responsibility of the user of this European Standard to validate the application for these matrices. For measurement in complex matrices like fly ashes adsorbed on vegetation it can be necessary to further improve the clean-up. This can also apply to sediments and mineral wastes.

The SIST EN 16190:2019 standard provides a comprehensive method for the determination of dioxins, furans, and dioxin-like polychlorinated biphenyls through high-resolution gas chromatography with mass selective detection (HR GC-MS). The document outlines a robust framework for the quantitative analysis of 17 specific 2,3,7,8-chlorine substituted dibenzo-p-dioxins and dibenzofurans, and their corresponding PCB congeners within various matrices, including soil, treated biowaste, and sludge. One of the significant strengths of this standard is its performance-based approach, which allows for methodological flexibility while ensuring that all performance criteria specified are fulfilled. This adaptability is crucial for laboratories that may need to tailor the technique to accommodate different sample types or specific analytical contexts. Users are given clear guidelines regarding the influences of sample type, congener, and the quality of chemicals used on detection limits, ensuring that they can optimize their methodologies effectively. The standard also asserts that under the defined conditions, detection limits can achieve performance thresholds better than 1 ng/kg (expressed as dry matter). This level of sensitivity is essential for environmental monitoring and regulatory compliance, as it enhances the precision of dioxin and furan quantification in complex matrices. Furthermore, the document notes that the method is not limited to the specified matrices; it can also technically be extended to include sediments, mineral wastes, and vegetation. However, it emphasizes the importance of user validation for these applications, thereby encouraging best practices in analytical measurement and reinforcing the standard’s relevance in diverse environmental contexts. Overall, SIST EN 16190:2019 stands as a critical tool for environmental professionals, ensuring accurate monitoring and compliance with health and safety standards concerning hazardous compounds in environmental samples.
