Overview

EN 16175-2:2016 specifies a validated analytical method for the determination of mercury in sludge, treated biowaste and soil using cold‑vapour atomic fluorescence spectrometry (CV‑AFS). The method applies to aqua regia or nitric acid digests prepared according to EN 16174 or EN 16173. The standard’s lower working range limit is 0.003 mg/kg (dry matter basis), and it includes requirements for calibration, reagents, apparatus and quality control.

Key topics and technical requirements

• Scope and matrices: Municipal sludge, treated biowaste (e.g. compost) and soil - validated matrices are explicitly listed.
• Analytical principle: Mercury(II/I) is chemically reduced (recommended: tin(II) chloride; alternative: sodium borohydride) to elemental Hg, stripped by an inert gas (argon or nitrogen) and measured by fluorescence at ~254 nm.
• Reagents & water quality: High‑purity reagents and Type 2 water (EN ISO 3696) are required. Prescribed acid solutions, Hg calibration stocks (1 000 mg/l down to µg/l levels), and fresh tin(II) chloride preparations are described.
• Instrumentation: Atomic fluorescence spectrometer with Hg lamp and 254 nm filter, a cold‑vapour generator (batch or automated flow/FIA), and an inert carrier gas supply. Use of automated flow systems improves sensitivity.
• Calibration & range: Calibration with multiple standards covering the test range (e.g. 0–20 µg/l in test solution) and appropriate dilution of samples above the calibration range. Sensitivity can be enhanced by amalgamation techniques.
• Interferences: Guidance on quenching by water vapour, suppression by noble metals (gold, silver) and complexing anions (sulfide, iodide, bromide). Tolerable concentrations for some matrix elements (e.g. Cu, Ni up to 500 mg/l; Ag ~1 mg/l) are specified.
• Quality and performance: Includes repeatability and reproducibility data from a European interlaboratory study; test reporting requirements are given.

Applications and users

This standard is intended for:

• Environmental and commercial analytical laboratories performing trace‑mercury monitoring.
• Wastewater treatment and sludge management facilities assessing contaminant levels.
• Soil testing and remediation projects requiring accurate mercury quantification.
• Regulatory agencies and compliance monitoring for biosolids, composts and soils.
• Research groups studying mercury fate in solid matrices.
