TABLE 1.

Concentrations of Cd within the Olfactory Sensory Epithelium Following the 48 h and 16-Day Cd Exposures and Following the 16-Day Depuration

Exposure time	Waterborne Cd Conc. (ppb)	Avg. Cd tissue conc. following exposure (ppm)	Avg. Cd tissue conc. following depuration (ppm)
48 h	0	<LOQ	<LOQ
48 h	2	0.74 ± 0.06	0.64 ± 0.09
48 h	30	4.51 ± 0.68*	2.97 ± 0.31*
16-day	0	<LOQ	<LOQ
16-day	0.3	1.29 ± 0.20	1.05 ± 0.09
16-day	2	5.91 ± 1.22*	3.71 ± 0.31*

 <LOQ: Concentration was less than the quantitation limit of 0.5 ppm. Data represents n = 3. Asterisks indicate statistically significant differences in Cd concentration relative to controls (*P ≤ .05).
