Overview

EN 16175-1:2016 specifies a validated laboratory method for the determination of mercury in sludge, treated biowaste and soil. The method applies to aqua regia or nitric acid digests prepared according to EN 16174 or EN 16173 and uses cold‑vapour atomic absorption spectrometry (CV‑AAS). The standard covers routine and trace-level analysis with a stated lower working range limit of 0.03 mg/kg (dry matter).

Key topics and technical requirements

• Scope: Mercury determination in acid digests of sludge, treated biowaste and soil (dry-matter basis).
• Analytical principle: Mercury(II/I) is chemically reduced to elemental mercury (Hg0) using tin(II) chloride (recommended) or sodium borohydride; Hg0 is swept by an inert gas into an AAS absorption cell and measured at 253.7 nm.
• Reagents & quality:
  • High‑purity water (EN ISO 3696) and acids (HCl, HNO3).
  • Mercury calibration standards (stock and working solutions) prepared as described.
  • Tin(II) chloride or NaBH4 reducing solutions prepared fresh or per instrument recommendations.
• Apparatus:
  • Atomic absorption spectrometer with cold‑vapour generator, quartz cell (10 cm typical), preferably an electrodeless discharge lamp and background correction.
  • Automated sample introduction/flow injection analysis (FIA) systems or batch cold‑vapour generators; carrier gas argon or nitrogen (≥99.99%).
• Performance & calibration:
  • Minimum of five calibration points across the expected concentration range; use matched acid matrix (diluted nitric acid or aqua regia).
  • Test blanks prepared alongside samples; dilution procedures specified (e.g., 10 mL digest to 100 mL).
• Interferences:
  • Matrix element tolerances listed (e.g., Cu(II) and Ni(II) up to 500 mg/L, Ag(I) 1 mg/L in the test solution). Tin(II) chloride reduces matrix interference compared with NaBH4.

Practical applications and users

• Environmental testing laboratories performing regulatory monitoring of soils, sewage sludge and treated biowaste for mercury contamination.
• Wastewater treatment operators and biowaste managers validating treatment effectiveness and compliance.
• Soil survey and remediation consultants assessing mercury levels for risk assessment and land-use decisions.
• Government and regulatory agencies requiring standardized, reproducible mercury data for enforcement and reporting.
