In addition, a three generation (FO through F3 <br /> weaning) study conducted by the NIEHS indicated that nonylphenol did not affect reproductive <br /> parameters at dietary concentrations up to 2000 ppm in any generation. Effects in juvenile <br /> females consistent with those seen in screening assays (e.g., premature vaginal opening)were <br /> observed following high level exposure post-weaning (F1, F2, and F3) at 650 and 2000 ppm. <br /> Sperm counts were reduced at 650 and 2000 ppm in the F2 adults compared to controls from <br /> the same generation. These results and other inconsistent or potentially body weight related <br /> findings are considered of questionable significance. The No Observed Adverse Effect Level <br /> (NOAEL)for reproduction was 2000 ppm and for all effects was 200 ppm (except as noted for <br /> kidneys above). Considering the high doses (e.g., 100-350 mg/kg/day for females in the 2000 <br /> ppm group; the higher doses occurring post-weaning), the lack of permanent/prolonged effects is <br /> considered significant. Based on the results of these studies, exposure to low doses of <br /> nonylphenol, such as from workplace or environmental exposure, would not be expected to <br /> result in effects on mammalian reproduction. In a 2-generation reproduction study with <br /> octylphenol at dietary concentrations of 0.2 to 2000 ppm, treatment-related effects in adult FO, <br /> F1, and F2 animals were limited to reduced body weights and feed consumption at 2000 ppm. <br /> No effects on any reproductive parameters were observed in either generation. No effects on <br /> sperm measurements, estrous cyclicity, or reproductive organs were observed in adult animals. <br /> Pup body weights during lactation were reduced at 2000 ppm. The NOAEL for systemic and <br /> postnatal toxicity was 200 ppm (approximately 15 mg/kg/day) and for reproductive toxicity was <br /> >2000 ppm (approximately 150 mg/kg/day). Although octylphenol has weak estrogen mimetic <br /> activity in some screening assays, no estrogenic or reproductive effects occurred from dietary <br /> exposure to rats for two generations over a 10,000 fold dose range. <br /> 12.
