Academic CentreTaking into account the multi-component chemical pollution, analytical control becomes topical, and it must be focused on the identification of a wide range of pollutants by applying gas chromatography. Using appropriate methodology, it is possible to detect organic compounds of high and low volatility in soil, municipal and industrial waste, wastewater and elsewhere. These types of methodologies can also be used to address various hygiene-related tasks, with the aim of finding new compounds without which it is not possible to assess the level of soil contamination or its degree of hazard. The results of the study can serve as a basis for sanitary, technical, reclamation and other measures to protect human health and living conditions.
- Preparation of the obtained samples for analysis
- Performing chemical analyses using the required methods
- Comparison of the obtained results with the maximum permissible concentration or indicative permissible concentration
- Preparation of results and assessment of the degree of hazard of the identified substances
ISO 22155:2016 Gas chromatographic method for the determination of volatile aromatic and halogenated hydrocarbons and individual ethers in soil with a static sample gaseous condition preparation/input system.
The method is applicable to all soil types. The border values (expressed on a dry matter basis) using a flame ionization detector (GC-FID) for volatile aromatic hydrocarbons is 0.2 mg/kg; aliphatic ethers such as methyl tert-butyl ether (MTBE) and tert-amyl methyl ether (TAME) are 0.5 mg/kg.
