| wastewater dilution index partially explains observed polybrominated diphenyl ether flame retardant concentrations in osprey eggs from columbia river basin, 2008-2009. | several polybrominated biphenyl ether (pbde) congeners were found in all 175 osprey (pandion haliaetus) eggs collected from the columbia river basin between 2002 and 2009. spbde concentrations in 2008-2009 were highest in osprey eggs from the two lowest flow rivers studied; however, each river flowed through relatively large and populous metropolitan areas (boise, idaho and spokane, washington). we used the volume of wastewater treatment plant (wwtp) discharge, a known source of pbdes, as a meas ... | 2011 | 21340556 |
