The effective enrichment of perfluoroalkyl acids (PFAAs) in sea spray aerosols (SSA) demonstrated in previous laboratory studies suggests that SSA is a potential source of PFAAs to the atmosphere. In order to investigate the influence of SSA on atmospheric PFAAs in the field, 48 h aerosol samples were collected regularly between 2018 and 2020 at two Norwegian coastal locations, Andøya and Birkenes. Significant correlations (p < 0.05) between the SSA tracer ion, Na+, and PFAA concentrations were observed in the samples from both locations, with Pearson’s correlation coefficients (r) between 0.4–0.8. Such significant correlations indicate SSA to be an important source of atmospheric PFAAs to coastal areas. The correlations in the samples from Andøya were observed for more PFAA species and were generally stronger than in the samples from Birkenes, which is located further away from the coast and closer to urban areas than Andøya. Factors such as the origin of the SSA, the distance of the sampling site to open water, and the presence of other PFAA sources (e.g., volatile precursor compounds) can have influence on the contribution of SSA to PFAA in air at the sampling sites and therefore affect the observed correlations between PFAAs and Na+.

Screening Programme 2022. New environmental pollutants.
The 2022 Screening Programme followed up on some findings from the 2020 Screening Programme. This included further
investigation of plastic-related substances, tyre-related substances, and disinfection agents. The 2022 Programme also included
additional new PFAS, bisphenols, and new siloxanes.

The Screening Programme 2021 was carried out by the Norwegian Institute for Water Research (NIVA) and NILU-Norwegian Institute for Air Research. The spotlight was placed on the occurrence and possible environmental problems of 218 chemicals. The selected substances may be included in numerous products and their usage patterns are not easily defined so an array of different locations and sample-types were investigated. The total number of results exceeds 26 000. Results are can be downloaded from the database Vannmiljø.

Screening Programme 2020, Part 1 and 2: Plastic Additives and REACH Compounds
I screening 2020 gjennomført av Norsk institutt for vannforskning (NIVA) og NILU-Norsk institutt for luftforskning i fellesskap ble det satt søkelys på forekomst og mulige miljøproblemer av 160 kjemikalier. Forbindelser som er valgt ut til Screening 2020 inkluderer tilsetningsstoffer til plast og nylig registrerte stoffer i REACH registeret.

Screening programme 2014. Phosphites, selected PBT substances and non-target screening. NILU OR
Forekomsten og miljørisiko av en rekke nye fosfitter og utvalgte PBT stoffer er rapportert for utslipp fra avløpsrenseanlegg og sigevann, samt sedimenter og biota fra Oslofjorden og Mjøsa. I tillegg ble det utført en hypotesefri miljøscreening av halvparten av alle biotaprøver.

Screening program 2018. Volatiles, Gd, BADGE, UV filters, Additives, and Medicines.
This screening project has focused on the occurrence and environmental fate of chemicals with possible PBT-properties. Samples were from indoor environments, surface waters, municipal wastewater, and the receiving marine environment. Some of the detected chemicals need to be studied in more detail. One UV-filter compound shows a potential environmental risk.

Screening of PFAS and Dechlorane compounds in selected Arctic top predators. NILU report
This report summarizes the findings of a screening study into the occurrence of selected perfluorinated compounds (PFCs) and dechloranes in Arctic top predators. The emerging PFCs F53 F53B, and PFBS were not detected neither in bird eggs nor in mammals. However, different dechloranes were detected in all samples.
