One can conclude from the passage that Asian industry appears to ____ .

Pollution is no respecter of national boundaries today. But
environmental scientists can still be surprised by the
distances that large quantities of industrial pollutants can
sometimes be carried by winds. For instance, a group of
chemists at the University of Washington in Seattle have
been involved in a case study of such pollutants which
reached the West Coast of America all the way from Asia.
They are keen to understand how such an event could
take place and to what extent it could have been forecast.
In fact, back in March 1997, pollutants such as carbonmonoxide
from Asia had been spotted as far across the
Pacific Ocean as Hawaii. Thus, it seems increasingly likely
that the West Coast of America is particularly exposed to
pollution from Asia.
