Recently, chlorinated paraffins with carbon chain lengths in the range C14–17 and chlorination levels at or exceeding 45 per cent chlorine by weight have been proposed for listing under the Stockholm Convention. To aid the process of determining the identification of sum polychlorinated alkanes ΣPCAs C14-17 under the regulation (i.e. number of chlorines), there is a need for data from environmental samples that specifies the homologue group profiles, not just ΣPCAs.
In this report we present data on PCAs with a focus on ΣPCAs C14-17 from the Norwegian Environment Agency’s monitoring programmes in more detail than available in the programmes reports, focusing on homologue group patterns and chlorination degree. The programmes are i) Environmental pollutants in the terrestrial and urban environment ii) Atmospheric contaminants iii) Environmental contaminants in an urban fjord. Data presented are from the 2022 (Halvorsen et al., 2023; Heimstad et al., 2023; Ruus, 2023) and 2023 (reports in prep) programmes.

Mission 5, as part of the NORAD financed IIEIA project, was undertaken to HCMC from 4 November to 4 December 2OO4. The air quality monitoring and management system has now been established and is being operated by trained TIEPA/DONRE experts. During Mission 5 we signed an agreement for the establishment of a Reference Laboratory and continued institutional building. NILU upgraded the AirQUIS system and we continued training the local experts. Data quality controls of air quality and meteorological data have been performed, and we continued collecting emission data for modelling purposes. During the mission we also prepared a paper on air quality in HCMC, which also will serve as a state of the environment report.
