The sources of annoying odours in the environment can be in particular polluted air from chemical installations, oil refineries, food industry, livestock farming and waste treatment plants as well as road traffic, domestic heating, agricultural activities and vegetation. An assessment of this nuisance is particularly difficult. As a rule, pollutants in ambient air can be detected objectively in terms of mass concentrations by means of physical/chemical measurement methods. Comparing measured or possibly calculated ambient concentrations with limit values generally does not involve any special problems. In contrast to this, odour in ambient air can hardly be determined and assessed with such procedures. As odour nuisance mostly occurs even at very low concentrations and moreover due to the combined action of several substances, the determination of substances by means of physical/chemical measurement methods is extremely costly or not possible at all…, Get the article to read more.
