In the preparation of the bibliography, the aim was to gather the publications concerned with the physiological effects of the pollution of the general atmosphere. It has seemed desirable to gather in addition to the reports on the major disasters and epidemiologic investigations, articles dealing with statistical findings of morbidity and mortality in which there is some mention of the incidence of diseases within urban versus rural areas. Several fairly extensive analytical surveys of atmospheric pollutants in various cities have also been included, so as to provide ready access to some of the data which have revealed the present extent of the contamination of the air with a number of materials and chemical compounds.
