Environmental Contaminants in an Urban Fjord, 2017
This programme, “Environmental Contaminants in an Urban Fjord” has covered sampling and analyses
of sediment and organisms in a marine food web of the Inner Oslofjord, in addition to samples of
blood and eggs from herring gull and eider duck. The programme also included inputs of pollutants
via surface water (storm water), and effluent water and sludge from a sewage treatment plant. The
bioaccumulation potential of the contaminants in the Oslo fjord food web was evaluated. The
exposure to/accumulation of the contaminants was also assessed in birds. A vast number of chemical
parameters have been quantified, in addition to some biological effect parameters in cod, and the
report serves as valuable documentation of the concentrations of these chemicals in different
compartments of the Inner Oslofjord marine ecosystem.

Air quality in Norwegian cities in 2015. Evaluation Report for NBV Main Results.
This report documents the final deliveries of the first phase of development of the Norwegian Air Quality Planning Tool,
also called “Nasjonalt Beregningsverktøy” or NBV. The main purpose of NBV is to provide a common methodological and
information platform for local air quality modelling applications. The system is addressed to local and regional
environmental authorities, air quality experts and consulting companies. It is intended to help them meet the requirements
of current air quality legislation, to support local air quality planning and facilitate air quality good practices where people live.
The report constitutes a comprehensive user guide for the NBV services available at http://www.luftkvalitet-nbv.no. It
presents each of the different products developed at NBV, documents how the product has been calculated, provides
recommendations on how best to use it for planning purposes and explains the main strengths and limitations of each
product. The report also includes an extensive validation of the air quality information currently available at NBV.

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.

Beregning av korrosjonsklasse fra miljøparametere i Fitjar. Lokasjon (59°56’11.5″N 5°19’58.4″Ø)
Korrosjonsklasse ble beregnet på lokasjon (59°56'11.5"N 5°19'58.4"Ø) i Fitjar, Vestland, Norge, fra årsgjennomsnitt for miljøparametere etter ISO 9223 og ISO 12944-2. Det ble funnet at korrosjonsklassen med høy sannsynlighet er C3 og at dette i hovedsak er bestemt av våt-tiden på omtrent 4500 timer/år, som gjennomsnitt i perioden 2007-2022. Dette er godt innenfor grensene for C3 når saltavsetningen er < 60 mg Cl-/m2døgn og SO2 konsentrasjonen i luft < 30 µg/m3. Disse betingelsene synes med stor sannsynlighet oppfylt på lokasjonen i Fitjar som årsgjennomsnitt i normalår.

The main goal of this feasibility study was to evaluate the potential of adding value to the Sentinel 5P TROPOMI methane product over Norway and the Arctic through the synergistic use of relevant observations from other Sentinel satellites and machine learning. We assessed the data availability of ESA operational and research-based WFMD XCH4 products over the Northern hemisphere, the Nordic countries and the Arctic/Northern latitudes. ESA’s XCH4 data have poor coverage over Norway. Seeing the two datasets as complementary, seems to be the most reasonable approach for utilization them. Furthermore, we investigated potential synergies between satellite products from different platforms. A random forest (RF) machine learning algorithm was implemented. It shows the importance of daytime land surface temperature (LST) as predictor variable for CH4. Our results indicate that the RF-model has a very good capability of filling small gaps in the data.

A life cycle perspective on the benefits of renewable electricity generation
In this report, the benefits of the use of RES to produce electricity are investigated from a life cycle perspective. Six different impact indicators for the production of electricity are estimated for all Member States in the period 2005 to 2018 for a total of sixteen different renewable and non-RES. Results show variability in impact intensities across Member States and years, depending among others on fuel conversion efficiency (for electricity produced using combustion processes) and capacity utilization (for electricity producing from non-combustion processes, such as wind power). Finally, an estimate is given on gross avoided impact by comparing historic values to a counterfactual scenario where the level of electricity production from RES is frozen at 2005 level. Results show that the increased use of photovoltaic and wind power have contributed significantly to gross avoided impacts across the investigated impact indicators. A trade-off is that the increased use of PV appears to have increased potential ecotoxicity related impacts of the European electricity production system. The increased use of solid biomass for the generation of electricity and heat generally has a positive effect on avoided impacts, at the cost of increased potential land occupation. Overall, these finding can aid policy makers and private actors direct efforts towards specific areas which offer opportunities to decrease the impacts.

This paper examines the creation of fine resolution maps at 100 m x 100 m resolution using statistical downscaling for the area of Prague, as a case study. This Czech city was selected due to the fine resolution proxy data available for this city. The reference downscaling methodology used is the linear regression and the interpolation of its residuals by the area-to-point kriging. Next to this, several other methods of statistical downscaling have been also executed. The results of different downscaling methods have been compared mutually and against the data from the monitoring stations of Prague, separately for urban background and traffic areas.
The downscaled maps in 100 m x 100 m resolution have been constructed for the area of Prague for three pollutants, namely for NO2, PM10 and PM2.5. Several methods of the statistical downscaling have been compared mutually and against the data from the monitoring stations. In general, the best results are given by the linear regression and the interpolation of its residuals, either by the area-to-point kriging or the bilinear interpolation. In the maps, one can see overall realistic spatial patterns, the main roads in Prague are visible through higher air pollution levels. This is distinct especially for NO2, while for PM10 and PM2.5 the differences between road increments and urban background are smaller as would be expected. The results of the case study for Prague have proven the usefulness of the statistical downscaling for the air quality mapping, especially for NO2. In addition, the population exposure estimates based on the downscaled mapping results have been also calculated.

There is considerable interest in identifying chemicals which have the potential to undergo long-range environmental transport (LRTP), accumulate in remote regions, and represent a possible risk to environmental and human health. In this report, we have screened a list of 1,000 organic chemicals, as well as selected brominated dioxins and furans (PBDD/Fs), for their potential to be dispersed, transferred to, and accumulated in remote regions. This screening was carried out applying a new set of LRTP metrics, collectively referred to as the emissions fractions approach (EFA), as implemented in a modified version of the OECD POV and LRTP (long-range transport potential) Screening Tool (The Tool).

Review of the Assessment of Industrial Emissions with Mosses
Commissioned by Norwegian Environmental Agency, NILU - Norwegian Institute for Air Research has surveyed the literature on the topic of “Assessment of industrial emissions using moss”. The purpose is to provide an overview of published knowledge on possible relationships between metal concentrations in moss and air quality, emissions, uptake in other organisms and impacts on environment and health. In addition, there was a request for information on whether other countries use moss surveys around industries and, if so, how the results are used by the authorities. The literature search resulted in 51 relevant publications, which mostly are from the period 2016-2019. The results of these publications show that moss is a good passive sampler for airborne contaminants and can provide valuable information on chemical signature and deposition of metals. No studies have been found that relates concentration in moss to air quality or amount emission from selected industries. A single 2019 study attempts to link moss concentration in context of health effects. A survey among the participating countries in ICP-Vegetation shows that results from moss surveys so far not have been used by authorities in a regulatory context.

Land cover and traffic data inclusion in PM mapping
Annual European-wide air quality maps have been produced using geostatistical techniques for many years and is based primarily on air quality measurements. The mapping method follows in principle the sequence of regression – interpolation – merging. It combines monitoring data, chemical transport model outputs and other supplementary data (such as altitude and meteorology) using a linear regression model followed by kriging of its residuals (‘residual kriging’), applied separately for rural and urban background areas. The rural and urban background map layers are
subsequently merged on basis of population densities into one final concentration map for Europe.
Inclusion of land cover and road type data among the set of the supplementary data demonstrated to improve the quality of urban and rural background layers in the NO2 map and is currently routinely applied in the NO2 mapping. In addition, an urban traffic map layer based on the measurement data from traffic stations is constructed and takes art in the merging process with the rural and urban background map layers to reach a final NO2 map.
This report examines now – due to its proved added value in the NO2 mapping – whether for PM10 and PM2.5 the similar method provides also sufficient added value to include it on a routinely basis in the production of the final concentration map and population exposure estimates.. It concerns the inclusion of land cover data and road type data in the background map layers, as well as the inclusion of the urban traffic layer based on traffic measurement stations. The analysis is done based on 2015 data, being the most recent year with all data needed available when this study started.

Low cost sensor systems for air quality assessment. Possibilities and challenges.
Air quality is enjoying popular interest in the last years, with numerous projects initiated by civil society or individuals that aim to assess the quality of air locally, aided by new, low-cost monitoring technologies that can be used by “everyone”. Such initiatives are very welcome, but in this highly technical and (in the western world) thoroughly regulated area, the professional community seems to struggle with communication with these initiatives, trying to reconcile the often highly technical aspects with the social ones. The technical issues include subjects such as monitoring techniques, air quality assessment methods, or quality control of measurements, and disciplines such as metrology, atmospheric science or informatics.
In this report, we would like to provide the reader with a practically oriented overview indicating the position of these new technologies in the ecosystem of air quality monitoring and measurement activities. Sensing techniques are rapidly evolving. This ‘ever’ improving capability implies among other, that there is currently no traceable method of evaluation of data quality. Despite the efforts of numerous groups, including within the European standardization system, a certification system will take some time to develop. This has important implications for example, when comparing measurements taken in time, by different devices (or different versions of the same sensor system device). Fitness for purpose – why are we measuring or monitoring and how do we intend to use the information we obtain – should always be the main criterion for the technological choice.
The report starts with an overview of elements of a monitoring system and proceed to describe the new technologies. Then, we give examples of how low-cost sensor technologies are being used by citizens. These examples are followed by reflections upon providing actionable information. Having learned from practical applications of sensor systems, we also discuss how the data from citizen activities can be used to develop new information, and provide some reflections on developing sensor systems monitoring on a larger scale.
We feel that the new technologies, while a disruptive change, provide many exciting opportunities, and we hope that this report will contribute to promote their use alongside with other assessment methods. We believe that increased understanding of technical issues we discuss will ultimately lead to better communication on air quality, and in its consequence, will enable further improvements in this domain.

Feasibility study for asphalt rubber pavements in Norway. ‘Rubber Road’ feasibility study.
RubberRoad proposes to use rubber from used tires in the production of asphalt for road and bicycle ways. This recycling approach has not gained much attention in Norway despite its apparent advantages, such as noise reduction, increased durability, safer shock impact, and reduced climate and environmental impacts. The Life Cycle Analysis carried out during this project feasibility study has demonstrated a series of environmental benefits in the use of rubber in asphalt production. It has also helped identify relevant knowledge gaps related to the use phase of the rubberized asphalt and its impact to noise, air and micro-plastic pollution. Better understanding of these effects would probably result in even larger environmental benefits of rubberized asphalt with respect to standard asphalt production. However, while the tire recycling industry is generally positive to the disposal of used tires in asphalt production, additional incentives need to be put in place for the Norwegian asphalt producers to consider actively contributing to this development.
