best data then available were for hexachlorocyclohexane (HCH). It was the only one of the
Arctic organochlorines we were monitoring at the time that possesses a significant degree
of water solubility; indeed, it was later found that because of this, a sizeable portion of the
HCH in the Arctic could arrive by marine transport. We now know that any relatively sol-
uble chemical should behave in the same way as HCH (such as toxaphene and endosulfan)
and that a sizeable portion of perfluorinated sulphonates (a substance we will look at later)
also arrives in the Arctic by oceanographic transport. Look at the discussion by Derek Muir
and Rainer Lohmann ( 2013 ) if you would like to learn more.
