“…The relative importance of the nature of the dust, however, or the unresponsiveness of the kiwi remain to be determined. Although discrete dust foci appear to be common to most pneumoconioses, the ability to react further varies according to the dust involved and the species of animal affected [5].…”

“…For example, anthracosis has been described in ponies working underground in coal mines [ 5 ] , and asbestosis has been recognised in the lungs of donkeys that worked in asbestos mines [l 11. Although poultry are frequently housed under dusty conditions [ l , 61, pneumoconiosis in birds is rare. ANDERSON et al [I, 21 conducted an experimental study of the effects of poultry house dust on the respiratory tract of chickens and turkeys.…”

Pneumoconiosis in the Captive New Zealand Kiwi

Abstract. Pneumoconiosis characterised by focal accumulations of dust-laden macrophages in the bronchial walls of lungs was found in 16 captive kiwis. The dust was shown to contain a large proportion of silica, some iron and probable plant material. The condition appears to be associated with dry, dusty aviaries. It was not seen in free-living kiwis.The characteristic food-seeking habits of the kiwi and the unique anatomical location of the external nares at the distal extremity of the beak probably predispose this bird to the disease.

Pulmonary macrophages consist of several subpopulations that can be defined by their anatomial locations as well as by other criteria. In addition to,the well-known alveolar macrophages that reside on the alveolar surface, pulmonary macrophages also occur in the conductingairways, in various pulmonar interstitial regions, and, in some mammalian species, in the lung's intravacular compartment. Other thoracic macrophages of relevance to puhnonary defense and some lung disem processesare the pleiural macrophages resident in the pleural space and macrophages present in regional lymph nodes that receive lymphatic drainge from the lung. Of the above subpopulations of pulmonar and thoracic macrophages, the alveolar macrophages have received the most experimental attention in the context ofthe pulmonary clearance and retenton of d particls. Accordingly, less infmationis currently alable rardig the roles other pulmonary and thoracic populations of a g may play inthe removalof partcles from the lower rsprtor tract and associatedtissue compartments. This report provides an overview ofthe various subpopulations of pulmonary and thoracic macrophages, as defined by their anaial locations. The known and postulated roles ofmacrophages in the pulmonary clearnce and retention of particles are reviewed, with particular emphasis on macrophage-associated processes involved in the pulmonary clearance of relatively insoluble particles.

Coal is an organic, combustible, rock‐like natural substance that occurs in various forms from hard and brittle anthracite to soft and friable lignite. Coal mine dust often contains silica and other minerals found within the coal seam or in the adjacent strata. In the United States and other countries, coal miners are at risk of developing chronic lung diseases caused by cumulative exposure to respirable coal mine dust. These diseases can lead to significant lung function impairment, disability, and premature death. Collectively known as “black lung,” they include a spectrum of interstitial lung diseases including coal workers' pneumoconiosis (CWP), mixed dust pneumoconiosis, and dust‐related diffuse fibrosis as well as chronic airway diseases including emphysema and chronic bronchitis. Since the late 1990s, the prevalence of CWP and its most severe form, progressive massive fibrosis, have increased in the United States, most notably in central Appalachia. Factors contributing to this resurgence might include thin‐seam coal mining and/or cutting rock to access coal seams, which likely exposes miners to respirable coal mine dust with a higher content of other hazardous dusts including silica and silicates. Many countries have occupational exposure limits for coal mine dust typically based on assessment of the mass of dust collected during a work shift.
