Excerpt
INTRODUCTION Vegetah1,e duste may be defined as aeroeols derived from plants regardless of the nature OF the particles that are emitted into the air during their harvesting, preparation, manufacture and transportation. Other natural dusts include animal danders, feathers, excreta, and microorganisms and their products. These dusts are numerous and varied in nature and are found in a number of major industries, but are especial.ly important in agriculture and the textile industry. The worldwide populatlon at potential risk from exposure to these dusts is extremely large. These exposures are particularly important in developing countries where the vast majority of workers and family members, including children, are engaged in agricultural activities and in small-scale manufacturing. When inhaled, these dusts exert a variety of harmful effects on the airways and on the lungs which may be classifled into three main types: occupational asthma, hypersensitivity pneumonitis, and nonspecific airways obstruction leading to chronic obstructive pulmonary disease. Byssinosis may be considered a fourth major syndrome in view of the characteristic symptomarology it presents, although in its terminal stages it leads to chronic obstructive pulmonary disease. Ae many of these dusts contain a wide range of different components, they eltcit more than one type of response which may make it difficult to recognize clear-cut clinical syndromes. Grain workers, for example,have a variety of responses because of the varying constituents and contaminants of grain duet.
