ISO 16198:2015 specifies the plant-based test, called biotest, which enables estimation of the environmental bioavailability of trace elements to plants either basically as the concentration in shoots and roots or in a more integrative way as the net uptake flux in plants.

Overview

ISO 16198:2015 defines a standardized plant-based test (biotest) to assess the environmental bioavailability of trace elements to plants. The method estimates bioavailability either as concentrations in shoots and roots or as a more integrative net uptake flux. The procedure combines a pre-growth phase in hydroponics with a subsequent exposure phase where plants grow in contact with soil or soil materials under oxic conditions. The standard is intended for soils, amended soils and soil materials, and is validated for a set of key trace elements.

Key topics and technical requirements

Biotest design: Two successive steps - pre-growth in hydroponics followed by plant growth in contact with test soil. Roots are in contact with soil without penetrating it, enabling rhizosphere processes while simplifying root recovery.

Endpoints: Measurement of trace element concentrations in shoots and roots and calculation of net uptake flux as an integrative bioavailability metric.

Target species: Standard suggests three species - cabbage (Brassica oleracea), tall fescue (Festuca arundinacea) and tomato (Lycopersicon esculentum) - with options to include other species (Annex A).

Validated trace elements: Includes As, Cd, Cr, Co, Cu, Pb, Ni, Zn; additional elements may be assessed where appropriate.

Apparatus and conditions: Specifies laboratory and biological apparatus, nutrient solutions, climatic conditions in growth chambers, sample pre-treatment, digestion and analytical methods (see Annexes for technical drawings and procedures).

Validity and data handling: Includes validity criteria, statistical analysis, data presentation, and reporting requirements to ensure reproducibility and comparability across labs.

Limitations: Not designed for trace elements prone to volatilization or for bioavailability from foliar deposition; not intended for organic contaminants without adapting the mesh to avoid sorption.

Applications and who uses it

ISO 16198:2015 is used by:

Environmental and soil testing laboratories for bioavailability assessment of trace elements.

Contaminated land assessors and remediation consultants for risk assessment, site comparison, and remediation effectiveness.

Regulators and policymakers setting soil quality standards and land-use decisions.

Agronomists and researchers studying plant uptake, rhizosphere interactions, and the impact of soil amendments (composts, sludges, wastewaters). Practical applications include comparing bioavailability across soils, validating chemical extraction methods against biological uptake, monitoring amended soils, and supporting land management or regulatory compliance.

Related standards

ISO 16198 references and complements other soil-quality standards such as ISO 17402 (bioavailability framework), ISO 11269-2 (effects on plant growth), and normative methods for water, pH and carbon analysis (e.g., ISO 3696, ISO 10390, ISO 10694). These related standards help ensure consistent sample preparation, analytical quality and interpretation.
