Klima- og miljødepartementet og Landbruks- og matdepartement ga 27. juni 2016 Landbruksdirektoratet, Miljødirektoratet og Mattilsynet i oppdrag å revidere forskrift om gjødselvarer mv. av organisk opphav. I oppdraget ble det lagt vekt på tilrettelegging for økt ressursutnyttelse av restmaterialer i gjødselvarer og at nyttiggjøringen skjer på måter som minimerer forurensning til vann, jord og luft...

Environmental Contaminants in an Urban Fjord, 2018
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.

Kartlegging av lokal luftkvalitet i Hønefoss. Målinger 2018-2019.
NILU - Norsk institutt for luftforskning har på oppdrag fra Ringerike kommune gjennomført kartlegging av lokal luftkvalitet i Hønefoss. Måleprogrammet startet juni 2018 og ble avsluttet i mai 2019. Målingene ble gjennomført for å framskaffe kunnskapsgrunnlag for ny byplan i Hønefoss.
Måleprogrammet inneholdt måling av svevestøv og nitrogendioksid samt meteorologiske parametre som temperatur, trykk, relativ fuktighet og vind.
Årsmiddelkonsentrasjonen av PM2,5 lå under øvre, men over nedre vurderingsterskel. Årsmiddelverdiene av NO2 og PM10 lå ikke over nedre vurderingsterskel. Døgnmiddelverdier av PM10 og timemiddelkonsentrasjon av NO2 lå under øvre, men over nedre vurderingsterskel.

This report presents the results from a screening study of volatile organic compounds (VOCs) in the Quintero-Puchuncaví
region (Chile). Two different methods were selected, one quantitative (canisters samplers / analysis by Medusa/GC-MS) and a second semi-quantitative (Tenax TA/analysis by GC-MS). NILU evaluated the results of 4 compounds (methyl chloroform,
nitrobenzene, iso-butane and toluene), which were previously reported at very high concentrations and intensively
discussed in the media. NILU’s measurement results show much lower concentrations and it was concluded that the former
measurements were done with a significant error in the calibration. The average concentration of ambient benzene was 1.0 µg/m3 at industrial areas and 0.3 µg/m3 at the residential/background areas, both lower than international limit values. The main compounds emitted from the industrial areas are light hydrocarbons, which were detected at low concentration levels.

Air Quality in Ny-Ålesund. Monitoring of Local Air Quality 2018.
The concentrations of the measured components are generally low and below national limit values for the protection of
human health and critical levels for the protection of vegetation.
Wind from northern sectors gave the highest average concentrations of nitrogen oxides and sulphur dioxide, which
indicates the power station and the harbour as possible sources. The measurement results for CO2 show an annual variation with higher concentrations in the winter and lower in summer. Measured concentrations of CO were most likely caused by local snowmobile traffic.

NILU’s Environmental Management Report 2018
One of NILU’s main goals is to study the impact of pollution and supply decision-makers with a sound scientific platform for choosing measures to reduce the negative impacts. Furthermore, it is very important for the institute to have control of the impact the institute’s own activities may have on the environment and to reduce negative impacts as far as possible.
NILU has for many years been working to improve the status of the environment and to reduce negative impacts. In order to
take this one step further, it was decided that the institute should restructure the work according to a relevant environmental standard and to seek certification according to the same standard.
The chosen standard is ISO 14001 (Environmental management systems—Requirements with guidance for use) and NILU
achieved certification according to this standard in October 2010. This report summarizes the results of the system in 2018.

Monitoring of greenhouse gases and aerosols at Svalbard and Birkenes in 2018. Annual report.
The report summaries the activities and results of the greenhouse gas monitoring at the Zeppelin Observatory situated on Svalbard in Arctic Norway during the period 2001-2018, and the greenhouse gas monitoring and aerosol observations from Birkenes for 2009-2018.
