A measure of the degree of saturation of the air with water vapour Particles which can penetrate to the deep unciliated regions of the lung Relative risk: the ratio of the incidence or prevalence in two groups Standard error Particles may be formed when two volatile and non-condensible vapour species react to give rise to a product with a very low vapour pressure. Such a product is described as a secondary particle to distinguish it from those arising from the reactions of liquids or solids In regression modelling, analysis designed to check how the results may vary with different underlying model assumptions Specific airways conductance. The reciprocal of sRaw [cm. H,O-1.sec~] A term used to describe a mixture of smoke and fog. Also used to describe photochemical air pollution Sulphur dioxide Sulphate Oxides of sulphur Measurement of the various subdivisions of lung volume and rates of flow A general term embracing all airborne particles small enough to remain in suspension for some hours or days Atmospheric haze produced during photochemical episodes: comprises secondary aerosols Tapered Element Oscillating Microbalance, an instrument for the continuous measurement of suspended particulate matter in air Describes that fraction of the particles which penetrates beyond the nasopharynx and larynx Studies of health of defined populations over a specified period of time The gravimetrically determined mass loading of airborne particles. Most commonly associated with use of the US high volume air sampler in which particles are collected on a filter for weighing Particles of less than 50 nm diameter Upper respiratory tract Maximum expiratory flow rate Volatile organic compounds of low molecular weight World Health Organization$
