&il sands operations are a si%nificant source of air pollution. "he lar%est source of air$orne pollution is the up%rader.
8(amples of air$orne contaminants include nitrous o(ides and volatile or%anic compounds. =any volatile or%anic
compounds are to(ic and they all com$ine with nitrous o(ides in the presence of sunli%ht to form %round level o>one.
&ne of the volatile or%anic compounds produced $y the oil sands is $en>ene, a carcino%en and a to(ic su$stance to
which there is no safe level of e(posure.
&il sands operations also emit lar%e +uantities of particulate matter which can $e carried deep into the lun%s and
contri$ute to health pro$lems such as $ronchitis and asthma.
;rom an environmental point of view, two of the most important pollutants released $y the oil sands are acid producin%
sulphur dio(ide and nitrous o(ides. 3l$ertas oil sands %enerate more than !:0,000 tonnes per year of nitrous o(ide
and sulphur dio(ide emissions. "hese are emitted in much hi%her +uantities than the conventional oil industry. *n the
ne(t set of slides we shall turn to a more detailed e(amination of their impacts.

Central facilities often include an up%rader, which converts $itumen into synthetic crude oil with the use of pressure
and steam. "he crude oil is then sent to a refinery for further processin%. "he up%rader is an ener%y intensive
operation and can thus have si%nificant pollution impacts.

=ultiple oil sands projects could make Saskatchewans %reenhouse %as emissions even worse. "his is $ecause if a
$arrel of oil is produced from in situ oil sands, the %reenhouse %as emissions are at least three times hi%her than if that

&nce in the atmosphere, sulphur dio(ide and nitro%en o(ides $ecome mi(ed and can travel lon% distances. *n the case
of 3l$erta and Saskatchewan, the prevailin% westerly winds carry 6:09 of the emissions from the ;ort =c=urray and
Cold ake area into Saskatchewan. 1urin% their transport, sulphur dio(ide and nitrous o(ide are involved in chemical
reactions with hydro%en chloride, o(y%en and water vapour. "hese reactions produce dilute solutions of nitric acid and
sulphuric acid, which ultimately fall as rain or snow on Saskatchewan soils and water $odies. *t can take $etween 2
and ! days $efore acid deposition on land or water occurs. 3s a result, acid deposition can take place as much as
!,000 kilometres away from the ori%inal pollution source.
