During these two decades, almost every country in Europe, as well as Japan, Australia, and New Zealand, experienced serious air pollution in its larger cities. As a result, these countries were the first to enact national air pollution control legislation. By 1980, major national air pollution research centers had been set up at the Warren Springs Laboratory, Stevenage, England the Institut National de la Sante et de las Recherche Medicale at... 

Nuisance levels for odors are not absolute, but are related to the minimum detectable level for 50 per cent of the population. These levels have been explored by Warren Spring Laboratories, who have concluded that five times the minimum detectable level is likely to give rise to complaint.

The Wheal Jane plant had incorporated flotation together with gravity since start-up of this plant. The flotation development testwork was carried out at the Warren Spring laboratory. The ore treated at the Wheal Jane plant is very complex and finely disseminated. About 86% is less than 50 pm, of which 50% is less than 20 pm.

Three experimental standards for olfactometric measurement were available and are compared in this review namely from France, the F.R.G. and the Netherlands. Moreover the guide for odour measurement from the Warren Spring Laboratory is considered as a guideline.

The Prosser olfactometer is a commercially-produced version of the portable olfactometer developed by the Warren Spring Laboratory (WSL) (2). The olfactometer (Figs. 1,2) contains two fans, which draw in ambient air through an activated carbon filter to remove extraneous odours and then mix this odour-free air with an odorous air sample before expelling the mixture through either a sample port (fan 1) or an exhaust port (fan 2) at 240 1/min.
