Note: in the 'Radar" graph below, each circle gridline represents a threshold that is
at least 10 times the level of the adjacent circle inside it (logarithmic scale). 
Example: a sample plotted between the 10 and 100 grid rings represent values that are
at least 10 to 99 times the value of samples between the 1 and 10 rings and 100 to 999 times
the value of samples between the 0.1 and 1 rings.  Lines connect all the values in a series.
The individual data points represent sample TEQ values from the chart that follows.

bulletGES memo (7/16/04) to the MDEQ indicates the results of the Dow/Entrix Wild Game study in the Tittabawassee River Flood plain confirms findings of MDEQ/GES 2003 T.River Aquatic Ecological Risk Assesement.  Conclusions:
bulletReview of the Entrix (2004) report has shown that the data contained therein support one of the major conclusions of the Michigan DEQ terrestrial ecological risk assessment (GES, 2004), that is that biota and food chains on the Tittabawassee River downriver of Midland are contaminated by PCDDs and PCDFs. A reasonable conclusion from this is that predators and scavengers at the tops of these food chains are likely to be even more exposed to these contaminants than the deer, squirrels, and turkeys sampled in the Entrix (2004) study.
bulletHowever, the Entrix (2004) study was designed to generate data for an evaluation of risk to human health, rather than to ecological receptors. Because of this, design elements in the Entrix (2004) study, though perhaps appropriate for a human health risk analysis, result in an underestimation of the contaminant concentrations to which wildlife would be exposed and, hence, the magnitude of the risks incurred. These design elements comprise:
bulletThe sampling was confined to organisms which, because of their diets, are unlikely to bioaccumulate PCDDs and PCDFs to the extent that other organisms would.
bulletThe carcass handling procedures resulted in a likely underestimation of the magnitudes of the PCDD/PCDF whole-body burdens to which predators and scavengers may be exposed.
bulletThe sample spatial distribution almost certainly results in an underestimation of the PCDD/PCDF body burdens of turkeys in the lower sections of the floodplain, and, hence, in the potential exposures to their predators and scavengers.
