Vandens kokybė. Plutonis ir neptūnis. Bandymas ICP-MS metodu (ISO/DIS 20899:2026)

This document specifies methods to determine the 239Pu, 240Pu, 241Pu and 237Np by inductively coupled plasma mass spectrometry (ICP-MS). The mass concentrations obtained can be converted into activity concentrations. Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by this method. To quantify 238Pu isotope by mass spectrometry, other techniques can be used (ICP-MS with collision-reaction cell, ICP-MS/MS with collision-reaction cell or chemical separation). Alpha spectrometry measurement, as described in ISO 13167,[8] is currently used[9]. The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. A chemical separation of Np and Pu, with quantitative removal of all other elements (including uranium, americium, etc.) is mandatory, given all the potential interferences that may bias the measurement or lead to false positives. Chemical separations can eliminate most of the 238U. However, use of reagents, glassware, and atmosphere for the chemical separation, will also add 238U to the samples and prevent measurement of 238Pu. The limit of detection depends on the sample volume, the instrument used, the background count rate, the detection efficiency, the counting time, and the chemical yield. The detection limit of the method described in this document, using currently available ICP-MS apparatus, is approximately 1 mBq·l-1 for 239Pu, 240Pu, 237Np and 1 Bq·l-1 for 241Pu, which is lower or of the same order of magnitude than the WHO criteria for safe consumption of drinking water (1 mBq·l-1 for 239Pu, 240Pu, 237Np and 10 Bq·l-1 for 241Pu[4]).This method covers the measurement of those radionuclides in water at activity concentrations between approximately[10][11]: — 1 mBq·l−1 to 5 Bq·l−1 for 239Pu, 240Pu and 237Np; — 1 Bq·l−1 to 5 Bq·l−1 for 241Pu. Samples with higher activity concentrations than 5 Bq·l−1 can be measured if a dilution is performed. The higher is the concentration factor, the lower are the LD and LQ expressed in Bq/L of water. A preconcentration is especially useful for the quantification of 241Pu that is usually the less abundant isotope of plutonium. The method described in this document is applicable in the event of an emergency situation. Filtration of the test sample is necessary. The analysis of 239Pu, 240Pu, 241Pu and 237Np adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is performed separately on each phase or the total phase. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

Neorganinės trąšos. Titrimetrinis amoniakinio azoto nustatymas

This document specifies a method for the titrimetric determination of the ammoniacal nitrogen content in inorganic fertilizers (including compound fertilizers), in which nitrogen is found exclusively either in the form of ammonium salts or ammonium salts together with nitrates. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizers are not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible. In the case of application to ammonium nitrate fertilizers of high nitrogen content, this document is not applicable to fertilizer product blends. This document is not applicable to fertilizers or fertilizer product blends containing urea, cyanamide, nutrient polymers or other organic nitrogenous compounds.

Dirvožemio gerinimo medžiagos ir auginimo terpės. Salmonella spp. aptikimas

This document specifies a method for the detection of Salmonella spp. in soil improvers and growing media. It is applicable to material in solid form (including pre-shaped growing media) and liquid form. This document is applicable to fertilizing product blends, where a blend is a mix of two or more fertilizing products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media comprise the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If soil improvers and/or growing media do not comprise the highest percentage in the blend, the European Standard for the highest percentage in the blend applies. In case a blend is composed of fertilising products in equal quantity, the user of the standard decides which standard to apply. Most of the Salmonella serovars are detected with the method described in this document. For the detection of some specific Salmonella serovars (e.g. Salmonella Typhi and Salmonella Paratyphi), additional cultivation steps can be necessary. NOTE 1 A soil improver or a growing medium consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite). NOTE 2 This method has been validated in an interlaboratory study with specific products that were present on the market during the study (Annex C).
