Soil quality - Determination of exchangeable acidity using barium chloride solution as extractant (ISO 14254:2018)

Soil quality - Determination of exchangeable acidity using barium chloride solution as extractant (ISO 14254:2018)

ISO 14254:2018 specifies a method for the determination of exchangeable acidity in barium chloride extracts of soil samples obtained according to ISO 11260.
The procedure described herein mainly concerns the determination of total exchangeable acidity by means of a fixed pH end point titration.
Two additional and optional procedures are given, describing respectively, determinations of free H+ acidity and aluminium in the extracts.
ISO 14254:2018 is applicable to all types of air dry soil samples.

Dieses Dokument legt ein Verfahren zur Bestimmung der Austauschacidität in Bariumchloridextrakten von Bodenproben fest, die nach ISO 11260 gewonnen wurden.
Das beschriebene Verfahren beinhaltet hauptsächlich die Bestimmung der austauschbaren Gesamtacidität mittels einer Titration bis zu einem festgelegten pH Endpunkt.
Es werden jedoch zwei zusätzliche und fakultative Verfahren angegeben, die zum einen die Bestimmung der freien H+ Acidität und zum anderen des Aluminiums in den Extrakten beschreiben.
Dieses Dokument ist auf alle Arten lufttrockenen Bodenprobens anwendbar.

SIST EN 17505:2024

This European standard specifies a method for the differentiated determination of the organic carbon content (TOC400) which is released at temperatures up to 400 °C, the residual oxidizable carbon (ROC) (including e.g. lignite (brown coal), hard coal, charcoal, black carbon, soot) and the inorganic carbon (TIC900) which is released at temperatures up to 900 °C.
The basis is the dry combustion to CO2 in a in the presence of oxygen using using temperatures ranging from 150°C to 900 °C in dry solid samples of soil, soil with anthropogenic admixtures and solid waste (see Table 1) with carbon contents of more than 1 g per kg (0,1 % C) (per carbon type in the test portion).

Soil, sludge, treated biowaste and waste - Determination of polycyclic aromatic hydrocarbons (PAH) by gas chromatography (GC) and high performance liquid chromatography (HPLC)
SIST EN 17503:2023

This document specifies different methods for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 2) in soil, sludge, treated biowaste, and waste, using GC-MS or HPLC-UV-DAD/FLD covering a wide range of PAH contamination levels (see Table 2).
NOTE   The method can be applied to sediments provided that validity is demonstrated by the user.
When using fluorescence detection, acenaphthylene cannot be measured.
[Table 2 -Target analytes of this document]
The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract.
Under the conditions specified in this document, the lower limit of application from 10 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 100 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples (e.g. bitumen) the limit of 100 μg/kg cannot be reached.
Sludge, waste and treated biowaste can differ in properties as well as in the expected contamination levels of PAH and presence of interfering substances. These differences make it impossible to describe one general procedure. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used.
The method can be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.
Sampling is not part of this standard. In dependence of the materials, the following standards need to be considered, e.g. EN 14899, ISO 5667-12 and EN ISO 5667-13.

This document specifies an operationally defined method for the direct determination of organically bound halogens (chlorine, bromine and iodine) adsorbed and occluded to the sample matrix. AOX being a methodologically defined parameter, it is essential that the procedure is applied without any modification.
This document is intended for analysis of sludge, treated biowaste or soil in concentrations ranging from 5 mg/kg dry matter. The upper limit and exact concentration range covered depend on the instrumentation used for determination.
NOTE This method can also be applied to other environmental solid matrices, provided the user has verified the applicability.

Soil quality - Determination of selected explosives and related compounds - Part 3: Method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) (ISO 11916-3:2021)
SIST EN ISO 11916-3:2022

This document specifies the measurement of explosives and related nitrocompounds (as given in Table 1) in soil and soil materials. This document is intended for the trace analysis of explosives and related compounds by liquid chromatography–tandem mass spectrometry (LC-MS/MS). Generally, LC-MS/MS measurement shows the lower LOQ (limit of quantification) for each compound in Table 1 than using high-performance liquid chromatography (HPLC) with UV-detection (see Annex B and Annex C).
Under the conditions specified in this document, concentrations as low as 0,005 mg/kg to 0,014 mg/kg-dry matter can be determined, depending on the substance. Similar compounds, in particular various nitroaromatics, by-products and degradation products of explosive compounds can be analysed using this method provided that the applicability is checked on a case-by-case basis.

SIST EN ISO 54321:2021

This document specifies two methods for digestion of soil, treated biowaste, sludge and waste by the use of an aqua regia digestion.
Digestion with aqua regia will not necessarily accomplish total decomposition of the sample.

It is generally agreed that for environmental analysis purposes, the results are fit for the intended purpose to protect the environment.
This document is applicable for the following elements:
Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), boron (B), cadmium (Cd), calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), phosphorus (P), potassium (K), selenium (Se), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tellurium (Te), thallium (Tl), tin (Sn), titanium (Ti), vanadium (V), and zinc (Zn).
