Mineralogical, Chemical, and Isotopic (Sr, Pb) Composition of Atmospheric Mineral Dusts in an Ombrotrophic Peat Bog, Southern South America
… of many major and trace elements and of mineral dusts. Geochemical studies of major and trace elements, mineralogy of atmospheric dust and their radiogenic isotope compositions in the peat, provide important information about the mineralogical host phases of major and trace elements transported …

The significance of indoor:outdoor relationships, and physical and chemical composition in personal exposure to urban particulate matter
… analysis of airborne particles and deposited dusts suggests that the majority of the particulate in the busy street canyon is likely to be diesel engine and vehicle related. The magnetic signature of the dusts collected from the street canyon also varies from dusts collected from other …

An investigation of pre- and post-emergence rots of garden peas and the results of trials with five fungicidal dusts as pea seed protectants
In this thesis the results of laboratory and field investigations into the cause and control of pre- and post-emergence rots of garden peas (Pisum sativum) are presented. These investigations were conducted during 1937-1938 at Canterbury Agricultural College, Lincoln.
