The samples were analyzed by electron spin resonance spectrometry (ESR). Accelerated fixation of CCA by steam treatment initially produced a strong chromium(V) ESR signal, which quickly decreased. Complete reduction of Cr(VI) to Cr(III) was achieved in 2 hours by steaming. Samples stored under ambient conditions still exhibited a moderately strong chromium(V) signal after 44 days. Oven drying of the CCA-treated samples for four days, failed to convert all of the chromium(V) intermediate to the trivalent form. Leaching of CCA-treated samples, confirmed that fixation was best achieved with the steam treatment. Oven drying caused the samples to leach large amounts of copper and smaller amounts of chromium and arsenic.}, keywords = {CCA, CHROMIUM, ESR, PRESERVATIVE FIXATION}, isbn = {0018-3830}, url = {://A1994MU80900001}, author = {Ruddick, J.
