Further observations on the short-term retention and clearance of asbestos by rats, using UICC reference samples / A.P. Middleton, S.T. Beckett and J.M.G. Davis

Sumario: Rats exposed to UICC chrysolite A, amosite and crocidolite at concentrations close to 1,5 and 10 mg/m3 of respirable fibre for a total of 120 h over a 6-week period were killed in five groups at approximately monthly intervals. The asbestos retained in the lungs was estimated by infra-red spectrophotometry after ashing. The results indicated different initial fractional retentions but that the rate of clearance was independent of the type of asbestos and of the concentration during exposure
