Phthalate concentrations in western fence lizard skin samples at 24 and 48 hour time points.

<p>Data for 24 hours and 48 hours are presented as log10 means (ng/g ± SE). Phthalate congeners are: di-methyl phthalate (DMP), di-iso-butyl phthalate (DIBP), and di-n-octyl phthalate (DNOP). Linear mixed effects models suggest significant effects of exposure route (χ² = 122.5, df = 2, p<0.001) and phthalate congener (χ² = 99.0, df = 2, p<0.001), and a significant effect of time (χ² = 9.13, df = 2, p = 0.002). See text for complete statistical information. Numbers above error bars indicate the number of detections out of 12 samples. At 48 hours, 2 oral treatment samples were lost during extraction and, therefore, detections listed are out of 10 samples.
