Abstract

Electrostatically precipitated respirable dusts from six major U.S. varieties and growing areas were analyzed. From 81-95% by weight, was under 15 micronm diameter. Composition was affected more by growing location than by variety. Dusts contained 16-28% ash, 8-9% moisture, and 62-76% organic matter, including 16-31% protein and 2-12% cellulose. Inorganic composition reflected soil type and minerals. Major elements were silicon, calcium, potassium, phosphorus, magnesium, and aluminum. Infrared spectra of dusts resembled proteins, but water extract spectra did not. Possible implications concerning byssinosis are discussed.

摘要

对来自美国六个主要品种及其种植区域的静电沉淀可吸入粉尘进行了分析。按重量计，81%至95%的粉尘直径小于15微米。成分受种植地点的影响大于品种。粉尘含有16%至28%的灰分、8%至9%的水分和62%至76%的有机物，包括16%至31%的蛋白质和2%至12%的纤维素。无机成分反映了土壤类型和矿物质。主要元素为硅、钙、钾、磷、镁和铝。粉尘的红外光谱类似于蛋白质，但水提取物光谱并非如此。文中讨论了与棉尘病相关的可能影响。
