Sorry, Allan, but you are wrong. Air pollution monitoring dates back much
longer than that. Some sort of monitoring was done in the latter half of
the nineteenth century and the early part of the twentieth century, when
fogs were a problem. The National Survey of Air Pollution was already
under way durign the major fogs of the 1950s and 1960s. Different
pollutants have been monitored over the past decade, but the overall level
is nothing like the level of the fogs of the 1950s and 1960s or of the
Edwardian era.
The trouble is that no one working on air polltuion today reads the
history.
