The monitoring and control of industrial emissions has been high on the environmental agenda for almost 50 years, since the first large-scale programmes to measure sulphur dioxide and \'black smoke\' were set up in 1961. Since then, air quality in the UK has greatly improved ? to the extent that the Hollywood-clich? ?peasouper? smogs are now but a distant folk memory.
