Earlier this month, Callie Lyons wrote an important piece about lingering questions regarding exposure to toxic C8 among residents of the Mid-Ohio Valley area. She explained:
… More than a decade after the deadly controversy came to light, in many ways the extent of the contamination remains unknown. The impact on local cattle, hens, milk, eggs and produce remains largely unmeasured … An extensive paper trail reveals that DuPont promised to fill in data gaps identified by the EPA as early as 2003, then repeatedly failed to deliver the requested information.
And now, we have a new peer-reviewed study from Harvard University that raises serious questions about the provisional health advisories that EPA issued in the final days of the Bush administration in response to concerns about water supplies polluted with C8:
The current EPA limit for this PFC is 300-fold higher. Thus, the recent evidence on PFC immunotoxicity in humans and toxicity in animal models suggests that current limits for drinking water contamination are too permissive and must be decreased substantially.
Current drinking water limits therefore need to be reconsidered in the light of the observed immunotoxicity associated with PFC exposure.
