Fig. 3. - The regions of the human respiratory tract in relation to airborne spore penetration and air velocity (Austwick 1966).
Other environmental factors influencing the type of allergy which may develop include the quantity of particles inhaled, which is depended on airborne concentration and length of exposure, and, of course, the nature of the particles themselves, i.e. fungal spores, pollen, dust, etc. Two types of allergy manifest in exposed people, viz. the «immediate» type resulting in an attack of the hay-fever type (Type I) with symptoms of rhinitis, eye irritation or asthma, and the «delayed» type (Type III) appearing some four to six hours after exposure and often referred to as «farmer’s lung type» (table 2). The latter is characterised by shortness of breath, cough, cyanosis and a slight rise in temperature, and whilst this may affect any person, the Type I allergy is virtually restricted to those individuals who are termed «atopic» and have an inherited susceptibility, especially to hay-fever. These two types of allergic reaction thus differ fundamentally and this provi<strong>des</strong> a good basis for dividing the subject, bearing in mind however, that in some instances the same organism may be involved in both types as can be seen by comparing tables 3 and 4. It is therefore useful to consi<strong>der</strong> both the domestic and occupational circumstances of each type of allergy and the associated environments.

Secondly, and more precisely, the radioallergosorbent test
