Dow Wild Game Study: Fish Data

SacFry-sm.jpg (11188 bytes)Note: The Dow wild game study did not include any facts or data pertaining to the dioxins impact on fish.

However, a review of the Dow data by the EPA and Dr. Hector Galbraith indicate the contamination has far reaching effects on fish and the humans and wildlife that consume them.

bulletThe contamination has similar characteristics regarding levels of risk and area affected as the Kalamazoo and Fox Rivers, which are currently a focus of the US EPA remediation plans.
bulletIt is clear than a persistent, un-addressed dioxin problem exists.
bulletUnacceptable, elevated cancer risk's to public health to frequent consumers of fish.
bulletPotential health risks to persons consuming game.
bulletDioxin contamination of game indicate contamination of the terrestrial food chain
bulletUnacceptable, serious aquatic ecological risks to fish, fish eating birds, and mammals.
bulletStrong consideration should be given to removal of dioxin contaminated  sediments and flood plain soil.
bulletThere is particular concern regarding distortions of risk information which are causing inaccurate risk messages to the public.

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.
