Answer 1

In 2007, Norway set up a measuring station at Troll, in Dronning Maud Land in Antarctica. The Norwegian Institute for Air Research (NILU) is responsible for monitoring among others mercury, organic pollutants, hydrocarbons and CO2. Preliminary conclusions from this monitoring confirm that concentrations of a number of organic pollutants in the atmosphere are lower than background levels in the Arctic. The measurements at Troll also show that HCB (a herbicide) is the dominant pollutant, as it is in the Arctic, too. The pollutant levels fluctuate through the year, in line with when coastal air masses meet the continent.[2
