Vandens kokybė. Nurodymai, kaip imti bentosinių stambiųjų bestuburių ėminius iš upėse ir upeliuose esančių buveinių proporcingai pagal jų dydį

This document gives guidance on procedures for the pro-rata multi-habitat sampling of benthic macroinvertebrates in rivers and streams. The term “pro-rata” reflects the intention to sample all the main riverine habitats present at a monitoring site according to the proportion of the site that it covers. It is an objective way to divide sampling effort among the different habitats. This guidance is applicable to all flowing waters, both artificial, modified and natural. This design enables comparable samples to be collected from any type of river, regardless of the habitats present. The pro-rata multi-habitat sampling is an overall approach rather than a specific method. This document is designed to: — support environmental and conservation agencies to meet the monitoring requirements of the WFD (Article 8, Annex II, and Annex V); — generate data sets appropriate for monitoring and reporting of sites designated under the Habitats Directive and the Birds Directive ensure that samples for comparing the overall composition of invertebrates from different stream types are comparable; — ensure samples for environmental quality assessments across different stream types are comparable even when sampled by different people; and — support river management and restoration initiatives. The pro-rata multi-habitat sample (MHS) provides: — a consistent way of sampling sites that is not dependent on the presence of particular types of habitat; and — guidance on a user-friendly strategy for collecting biological data depending on the distribution of substrate type. It is also ideal for: — understanding the distribution of biological community types across different physical river types; and — quality assessments based on deviation from reference, as adopted in the European Water Framework Directive.

Vandens kokybė. Polibromintų difenileterių (PBDE) nustatymas nuosėdose, skendinčiosiose (kietosiose) dalelėse ir biotoje. Dujų chromatografijos ir divigubosios masių spektrometrijos arba didelės skyros masių spektrometrijos metodas (GC-MS/MS; HRMS) (ISO/DIS 22032:2025)

This document specifies a method for the determination of selected polybrominated diphenylethers (PBDE) (see Figure 1 and Table 1) in sediment, suspended particulate matter and biota using gas chromatography/ mass spectrometry (GC-MS/MS or GC-HRMS) in the electron impact (EI), negative ion chemical ionization (NCI) or atmospheric pressure ionization (APCI) mode. Figure 1 — General structure of polybrominated diphenyl ethers The method is applicable to sediment and suspended particulate matter samples with limits of quantification of 0,2 μg/kg dry weight (dw) for BDE-28 to BDE-183, of 2 μg/kg dry weight (dw) for BDE‑209. The method is applicable as well with lower limits of quantification (LOQ), if specific clean-up methods, described in Clause 10, Table 3, method 1 and method 2 in combination with measurement methods GC-MS/ MS or GC-HRMS after electron impact ionization (El) or negative ion chemical ionization (NCI) for BDE-209 are used. Depending on the analytical capability of the instrument limits of quantification down to 0,003 μg/ kg dw for BDE-28 to BDE-154 and 0,02 μg/kg dw for BDE-183 and 1 μg/kg dw for BDE-209 and lower are possible. The method is applicable to biota samples with limits of quantification down to 0,000 2 μg/kg fresh weight (fw) (BDE-28 to BDE-154) and 0,03 μg/kg fresh weight (fw) (BDE-183), if specific clean-up methods, described in Table 4 in combination with measurement methods GC-MS/MS or GC-HRMS after electron impact ionization (El) are used.

Vandens kokybė. Augančių mikroorganizmų skaičiavimas. Kolonijų skaičiavimas po sėjimo ant R2A terpės (ISO/DIS 13647:2025)

This document specifies a method for the enumeration of culturable microorganisms in water by counting the colonies on a low-nutrient agar culture medium by spread plate inoculation after incubation at 22 °C for 7 d. The method is intended to measure the operational efficiency of the treatment process of public drinking water supplies, including the water in distribution systems and containers. The method is particularly suitable to monitor water for human consumption which is low in nutrients and is distributed in temperatures below 20 °C (Reference [1]). The method can be applied to all types of water, including pool and spa waters. The low-nutrient agar in use in this document usually gives higher colony counts from water samples than nutrient-rich formulations of culture media typically used for enumeration of culturable microorganisms (References [2], [3], [4]).

Aplinkos oras. Biologinė stebėsena naudojant aukštesniuosius augalus. Standartizuotas žolės ekspozicijos metodas

This document applies to the use of the grass Lolium multiflorum ssp. italicum designated hereafter as Italian ryegrass for the bioaccumulation of substances liable to cause atmospheric pollution. It is an active biomonitoring approach insofar as the plants used are first cultivated in set conditions before being exposed at the monitoring locations in the field. The plants then record any pollution events that occur while they are being exposed, allowing such events to be accurately dated. The method described in this document can be applied for identification and localization of one or more single pollution sources and the tracking of their “plume” on a local or regional scale. It also offers a tool to monitor sites in the long term by the repeated application of a clearly defined procedure and to describe the local or regional air pollution situation. The method applies to solid and gaseous substances deposited on plants, where they may accumulate on their surface or in their tissues. These substances include sulphur, chloride, fluoride and especially metals as well as low volatile organic and halo-organic compounds such as polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), polybrominated diphenyl ethers (PBDE), polychlorinated dibenzo dioxins (PCDD) and polychlorinated dibenzo furans (PCDF). It is as well possible to verify pesticides which are used in plant protection products. The range of potential substances may be expanded according to the task at hand and the capabilities of conducting trace analyses and assessment. The method described in this document allows spatial and temporal comparisons and allows for screening, thus providing a first indication of risk. The results of grass culture studies can suggest risks to biota (e.g. via the food chain) which require further investigation. The method described in this document does not replace physico-chemical methods of direct measurement or modelling of air pollutants and cannot be replaced by them for its part; it complements them by indicating biological effects. Potential areas of deployment are: - Permit procedures related to air pollution legislation; - Preservation of evidence related to the code for protection from pollution; - Monitoring of emission sources and performance control; - Assessment of local-scale emission transport; - Evidence of causation, e.g. related to environmental liability; - Air quality maintenance plans/strategies; - Long-term monitoring of ecological effects of atmospheric depositions; - Detection and assessment of local, regional, and countrywide effects of atmospheric depositions; - Assessment of risks for humans and/or animals via the food chain. This document is of interest to those involved in environmental monitoring.
