It is well known that environmental pollutants such as PCBs that originate from industrialized countries accumulate in the food chain in the Arctic to high levels in species such as Polar bears and Glaucous gulls, both top predators in this environments. Trends in “old” toxins have been observed to be decreasing in recent years, due to bans of relevant substances for example in the EU. It takes a long time for levels to decrease because all relevant substances have in common that they are long-lived, they are still used illegally and some countries have so far failed to issue bans.
The bad news is that new organic pollutants have been found. Production of chemicals for fireproof materials (electronics, furniture, clothing) seems to be the most significant source. Perfluorooctanesulfonic acid (PFOS) seems to be an important new threat; this substance has already reached high levels for example in fat tissue of Polar bears in Svalbard.
Also regional CO2 levels continue to show alarming trends. CO2 is mixing quickly in the atmosphere over the globe, which means that regional trends reflect the global development. The atmospheric observatory on Zeppelinfjellet near Ny Ålesund in Spitsbergen, the average for the first 100 days of 2008 was 391.1 ppm (parts per million), as compared to 388.8 ppm for the same period in 2007. Single measurements beyond 400 ppm are likely to be observed in 2009.
