Passage 1
      When people think of the Arctic, they probably imagine a pure and beautiful –   21   harsh –environment. So it is an unwelcome surprise, perhaps, that the region’s native animals and peopleare among the most chemically contaminated on Earth.
      Recently, various studies were conducted to   22    the levels of toxic chemicals in the bodiesof Arctic animals, as well as in the native Inuit people. The statistics are alarming. Both the animals,and the Inuit who participated in the studies showed unusually high levels of man-made toxins.
      These included older pollutants like dioxins and PCBs which many governments have beentrying to      23   since the 1970s. Such chemicals are known to   24   our hormones anddamage the immune system. The studies also found newer compounds – ones that currently havewidespread approval for use in flame retardants –   25   in the Inuits’ bodies at a ratio of five toone compared to levels found in other Canadians.
