So, quoting a 23 year old publication and ignoring more current juried articles with contrary findings firmly supporting C-123 veterans' claims, VA's Post Deployment Health unit concluded C-123 veterans were not exposed. Because the dermal barrier is near-perfect, they told us. Anything to block disability claims.
They're wrong. VA VHA issued a blatant twist of facts. Along with similar conclusions in TG312, here what the CDC/Agency for Toxic Substances and Disease Registry said, confirming our OCCUPATIONAL EXPOSURE resulted in dermal absorption – BIOAVAILABILITY!
"[T]he ability of the skin to absorb dioxins (bioavailability)is slow except during occupational exposures." (p.5)Also, the Japanese Environmental Agency:
"Oral Intake and Absorption: Dioxins are absorbed through the gastro-intestinal tract, skin, and lungs. The degree of absorption varies with the congener, the route of absorption,and the medium."Thus, even with VA's twisted redefinition of exposure (exposure = contamination field + bioavailability) we have federal agency support for both our exposure and the bioavailability.
