Agent Orange Dioxin Research: Exposure To Environmental Toxins Causes Next Three Generations To Be Affected

March 05, 2012

A Washington State University researcher has demonstrated that a variety of environmental toxins can have negative effects on the genes of not just an exposed organism but the next three generations of its offspring.

The animal's DNA sequence remains unchanged, but the compounds change the way genes turn on and off — the epigenetic effect studied at length by WSU molecular biologist Michael Skinner and expanded on in the current issue of the online journal PLoS ONE.

Increasingly, biologists are finding that non-genetic variation acquired during the life of an organism can sometimes be passed on to offspring–a phenomenon known as epigenetic inheritance.

While Skinner's earlier research has shown similar effects from a pesticide and fungicide, this is the first to show a greater variety of toxicants — including jet fuel, dioxin, plastics and the pesticides DEET and permethrin — promoting epigenetic disease across generations.

    My daughter has many health problems  and I believe they are related to her fathers exposure to Agent Orange. Do you know of any research or help through the VA for these kids. I know there are thousands of them out there. I have read their stories.
