Survey of emissions of volatile organic chemicals from handheld toys for children above 3 years
NILU has, on behalf of the Norwegian Environment Agency, performed a screening study to identify volatile organic chemicals (VOCs) emitted from handheld toys for children. The goal was to identify individual VOCs emitted from toys at room temperature and to evaluate what impact the toys may have on the composition and concentrations of VOCs in indoor air. 12-30 individual VOCs were identified in each toy and 65-143 individual VOCs were detected with a concentration higher than 1 µg/m3. VOCs emitted at high concentrations and/or with hazardous properties were cyclohexanone, aromatic VOCs (xylenes, toluene, ethylbenzene), cyclic siloxanes and 2,2,4-Trimethyl-1,3-pentanediol diisobutyrate (TXIB). A regulated hydrochlorofluorocarbon (HCFC-141 b) was also detected from 5 toys. The toys with high concentrations of cyclohexanone and cyclic siloxanes affected the composition and concentrations of VOCs in indoor air.

The ClairCity Horizon2020 project aims to contribute to citizen-inclusive air quality and carbon policy making in middle-sized European cities. It does so by investigating citizens’ current behaviours as well as their preferred future behaviours and policy measures in six European cities1 through an extensive citizen and stakeholder engagement process. The project also models the possible future impacts of citizens’ policy preferences and examines implementation possibilities for these measures in the light of the existing institutional contexts in each city (Figure 0-1). This report summarises the main policy results for Amsterdam (the Netherlands).

This report presents VOC (volatile organic compound) measurements carried out during 2018 at EMEP monitoring sites. In total, 20 sites reported VOC-data from EMEP VOC sites this year. Some of the data-sets are considered preliminary and are not included in the report.
The monitoring of NMHC (non-methane hydrocarbons) has become more diverse with time in terms of instrumentation. Starting in the early 1990s with standardized methods based on manual sampling in steel canisters with subsequent analyses at the lab, the methods now consist of a variety of instruments and measurement principles, including automated continuous monitors and manual flask samples. For oxygenated VOCs (OVOCs), sampling in DNPH-tubes with subsequent lab-analyses is still the only method in use at EMEP sites.
Within the EU infrastructure project ACTRIS-2, data quality issues related to measurements of VOC have been an important topic. Many of the institutions providing VOC-data to EMEP have participated in the ACTRIS-2 project, either as formal partners or on a voluntary basis. Participation in ACTRIS-2 has meant an extensive effort with data-checking including detailed discussions between the ACTRIS community and individual participants. There is no doubt that this extensive effort has benefited the EMEP-program and has led to improved data quality in general.
Comparison between median levels in 2018 and the medians of the previous 10-years period, revealed a similar north-to-south pattern for several species.
Changes in instrumentation, procedures, station network etc. during the last two decades make it difficult to provide a rigorous and pan-European assessment of long-term trends of the observed VOCs. In this report, we have estimated the long-term trends in NMHC over the 2000-2018 period at six sites by two independent statistical methods. These estimates indicate marked differences in the trends for the individual species. Small or non-significant trends were found for ethane over this period followed by propane which also showed fairly small reductions. On the other hand, components linked to road traffic (ethene, ethyne and benzene) showed the strongest drop in mean concentrations, up to 60-80% at some stations.
The persistent heatwave in summer 2018 in northern and central Europe lead to higher isoprene-levels than normal. The data indicate a clear relationship between isoprene and afternoon temperature at the sites. An exponential fit is seen to be well suited for the relationship between isoprene and temperature.

Equinor Mongstad. Spredningsberegninger av utslipp til luft.
NILU har vurdert spredning av utslipp til luft fra Mongstad raffineri. Bakgrunnen er krav fra Miljødirektoratet i forbindelse med ny virksomhetstillatelse. Fokus i studien er på NOx, SOx og støv/partikler. Timemiddelkonsentrasjoner er beregnet ved hjelp av modellen CONCX. Regionale beregninger av konsentrasjoner og avsetning er utført med WRF-EMEP modellsystem. CONCX-beregningene viser at maksimalt beregnet timemiddel er langt lavere enn norske grenseverdier. WRF-EMEP-beregningene viser lave maksimumsverdier av NOx/NO2, SO2 og svevestøv/PM10 i nærområdet til Mongstad raffineri. Alle beregnede maksimumsverdier er lavere enn norske grenseverdier. Av utslippene fra Mongstad avsettes 12 % av nitrogen, 17 % av svovel og 18 % av PM10 innenfor det innerste gridet (105 x 105 km2). Som et tillegg er det gjort vurderinger av de prioriterte stoffene bly, kvikksølv, krom, PCB7, kadmium og arsen. Bidraget fra Mongstad raffineri er lite.

Målinger av SO2 i omgivelsene til Elkem Carbon og REC Solar. September 2019 – august 2020.
På oppdrag fra Elkem Carbon AS har NILU utført målinger av SO2 i omgivelsene til Elkem Carbon og REC Solar i Vågsbygd
(Kristiansand kommune). Bedriftene ble pålagt av Miljødirektoratet å gjennomføre SO2-målinger i omgivelsesluft. Målingene ble utført med SO2-monitor i boligområdet på Fiskåtangen (Konsul Wilds vei) og med passive SO2-prøvetakere ved 6 steder rundt bedriftene. Rapporten dekker målinger i perioden 1. september 2019 – 31. august 2020. Norske grenseverdier for luftkvalitet (SO2) ble overholdt ved Konsul Wilds Vei for alle midlingsperioder krevet i forurensningsforskriften (årsmiddel, vintermiddel, døgnmiddel og timemiddel). De mest belastede stedene i måleperioden var Konsul Wilds vei og Fiskåveien rett sør for bedriftene.

EEA-33 Industrial Emissions Country Profiles. Methodology report. Updated July 2020.
The industrial emissions country profiles summarise key data related to industry: its relevance with respect to economic contributions, energy and water consumption, as well as air and water emissions and waste generation. The country profiles are developed for the EEA-33 countries which includes the 28 EU Member States together with Iceland, Lichtenstein, Norway, Switzerland and Turkey.
The present revision (v. 3.0) of this report includes data available at date of release. This year, a new reporting, the so-called EU-Registry and thematic data reporting, is introduced in order to gather the former E-PRTR, LCP and IED reportings and finally replace them. The 2018 data are not yet readily available. Nevertheless, more quality checks have been performed on the latest E-PRTR database in order to have the cleanest final E-PRTR dataset possible. Hence, the industrial emissions country profiles are enriched with the most up-to-date data sources while still only covering the years up to 2017.
This report describes the underlying methodology to the industrial emissions country profiles that are presented as a Tableau story on the EEA webpages ([1]).
The scope of industry in this respect includes in short all industrial activities reported under the European Pollutant Release and Transfer Register (E-PRTR) excluding agriculture (activity code 7.(a) and 7.(b)). The data sources include Eurostat, the E-PRTR, greenhouse gas (GHG) emissions reported under the Monitoring Mechanism Regulation (MMR) and air pollutant emission inventories reported under the Convention on Long-range Transboundary Air Pollution (CLRTAP), each of which have their own data categories. A recently developed EEA-mapping which align these different categories is used ([2]). The data sources and industry scope is presented in full detail in the Annexes following this report.
The water and air pollutants including greenhouse gases are selected based on criteria related to their relative impact. Emissions of heavy metals to air and water have been combined by weighted averages using both eco toxicology and human toxicology characterisation factors ([3]). The amounts of hazardous and non-hazardous waste reported under Eurostat is presented, but excluding the major mineral waste that dominates the mining and construction sectors.
The data quality is evaluated and gap filling of Eurostat data is performed when needed. A method for E-PRTR outlier handling is proposed and applied where appropriate.
The significance of industry, given by gross value added (GVA), energy consumption and water use, as well as generation of waste are presented in the Tableau story as a sector percentage of EEA-33 gross total as well as percentage of country total. The trend in air and water pollution is presented as totals per pollutants relative to the latest year (2017). For the latest year the emissions are also given as percentage per sector relative to country total. The details on how the presented data is processed and aggregated is described in Annex 2.
The report is to a large extent based on previous methodology reports for “Industrial pollution country profiles”, but is also further developed to reflect feedback received through Eionet review and general requests from EEA and the European Commission.
