A STUDY OF FISCHER 344 RATS EXPOSED TO SILICA DUST AT CONCENTRATIONS OF 0, 2, 10 OR 20 MG/M3, THEN MAINTAINED FOR SIX MONTHS PRIOR TO ASSESSMENT.
The major objective of this study was to relate the results of a series of functional tests to the compositional and structural alterations in the rat lung induced by subchronic exposure to silica dust. To induce a fibrotic lesion, Fischer-344 rats were exposed to either 0, 2, 10, or 20 mg Si0{sub 2}/m{sup 3} for 6 hours/day, 5 days/week for six months and then maintained in an animal room, equipped with a laminar flow unit, for six months prior to assessment of the end points.
