Validation of an Asthma Questionnaire in Spanish

(PNASH Pilot, 1995-2000) Researchers characterized the relationships between various bioaerosol-related assays during composting operations using agricultural wastes. The assays included were standard microbiological assays (high and low temperature incubation for fungi and bacteria) on samples taken on filter cassettes, 1-3 b d glucan, possibly 1-6 b d glucan, and an extracellular polysacharride (EPS) specifically associated with aspergillus and penicillium species. Sampling was conducted during both winter and spring/summer conditions at a variety of operations composting yard waste, biosolids, agricultural waste (including fruit pulp and mint sludge), and dairy manure.
