With this method, phenols and chlorophenols can be determined at the lowest of mass concentrations ranging from approximately 0,01 mg/kg to 0,1 mg/kg depending on the component sensitivity and the quantity of sample used. In some cases, complete separation of isomers cannot be achieved. Then the sum is reported.

NOTE With this method, other higher methylated phenols can also be analysed provided that the suitability and the validity of the method is proven.

Arsenic (As), cadmium (Cd), cobalt (Co), lead (Pb), antimony (Sb), thallium (Tl), vanadium (V).

This method may be applied to other elements. The lower working range is approximately 0,01 mg/kg to 0,001 mg/kg, depending on the element to be determined.

Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), boron (B), cadmium (Cd), calcium (Ca), cerium (Ce), cesium (Cs), chromium (Cr), cobalt (Co), copper (Cu), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), gallium (Ga), germanium (Ge), gold (Au), hafnium (Hf), holmium (Ho), indium (In), iridium (Ir), iron (Fe), lanthanum (La), lead (Pb), lithium (Li), lutetium (Lu), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), neodymium (Nd), nickel (Ni), palladium (Pd), phosphorus (P), platinum (Pt), potassium (K), praseodymium (Pr), rhenium (Re), rhodium (Rh), rubidium (Rb), ruthenium (Ru), samarium (Sm), scandium (Sc), selenium (Se), silicon (Si), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tellurium (Te), terbium (Tb), thallium (Tl), thorium (Th), thulium (Tm), tin (Sn), titanium (Ti), tungsten (W), uranium (U), vanadium (V), ytterbium(Yb), yttrium (Y), zinc (Zn) and zirconium (Zr).

The working range depends on the matrix and the interferences encountered.

The limit of detection is between 0,1 mg/kg dry matter and 2,0 mg/kg dry matter for most elements.

The results of the test carried out can be used for risk assessment studies related to contaminations with petroleum hydrocarbons.

ISO/TS 16558-2:2015 provides a method applicable to petroleum hydrocarbon contents from about 100 mg/kg soil expressed as dry matter for the whole aliphatic fraction C10 to C40, as well as the aromatic fraction C10 to C40. For sub-fractions, lower limits of determination can be reached.

If lower detection limits are required, large volume injection can be used or concentration of the final extract can be carried out.

NOTE 1 Low concentrations of aliphatic and aromatic compounds can be found in natural uncontaminated organic rich soils like peat soils.

L'ISO/TS 14256-1:2003 est applicable à tous les types de sols homogénéisés à l'aide de méthodes appropriées.

For sludge, a limit of detection of 0,1 mg/kg and for soil and treated biowaste of 0,02 mg/kg (expressed as dry matter) may be achieved.

ISO/TS 13896:2012 specifies the determination of the sum of LAS. Under the conditions specified in ISO/TS 13896:2012, typically a limit of detection of 20 mg/kg (expressed as dry matter) for sludge and of 0,2 mg/kg to 0,5 mg/kg for soil and treated biowaste may be achieved.

Lower limits of detection may be achieved by concentrating the extract by solvent evaporation.
