Melkøya ferskvann, nedbør, vegetasjon og jord 2024
I 2024 var det igjen tid for den tradisjonelle overvåkningen av ferskvann. I forbindelse med endringer i produksjonen og mulige økte utslipp av kvikksølv ble det gjort enkelte endringer i programmet for ferskvann samtidig som det ble iverksatt undersøkelser av kvikksølv (Hg), bly (Pb) og polysykliske aromatiske hydrokarboner (PAH) i nedbør, vegetasjon og jord. I det nye programmet er det god samlokalisering mellom prøvetakingsstasjoner for ferskvann, nedbør, vegetasjon og jordprøver.
Det ble gjennomført innsamling av prøver i ferskvann, nedbør, vegetasjon og jord fra starten av september.

The MEMORI project (Grant agreement 265132) was performed in the period 2010-2013. The project was coordinated by NILU-Norwegian Institute for Air Research, and included 14 partners, four subcontractors and an advisory end-user group with 8 members. MEMORI aimed at providing the conservation market with innovative, non-destructive, and early warning technology for easy assessment of environmental impact on indoor cultural heritage. For this purpose, a dosimeter and a portable reader instument were produced. In addition, a new web-based result's and presentation mitigation tool was developed.

Exposure to mercury (Hg) is a global concern, particularly among Arctic populations that rely on the consumption of marine mammals and fish which are the main route of Hg exposure for Arctic populations.The MercuNorth project was created to establish baseline Hg levels across several Arctic regions during the period preceding the Minamata Convention. Blood samples were collected from 669 pregnant women, aged 18–44 years, between 2010 and 2016 from sites across the circumpolar Arctic including Alaska (USA), Nunavik (Canada), Greenland, Iceland, Norway, Sweden, Northern Lapland (Finland) and Murmansk Oblast (Russia). Descriptive statistics were calculated, multiple pairwise comparisons were made between regions, and unadjusted linear trend analyses were performed.Geometric mean concentrations of total Hg were highest in Nunavik (5.20 µg/L) and Greenland (3.79 µg/L), followed by Alaska (2.13 µg/L), with much lower concentrations observed in the other regions (ranged between 0.48 and 1.29 µg/L). In Nunavik, Alaska and Greenland, blood Hg concentrations have decreased significantly since 1992, 2000 and 2010 respectively with % annual decreases of 4.7%, 7.5% and 2.7%, respectively.These circumpolar data combined with fish and marine mammal consumption data can be use
