Dioxin is one of only a handful of chemicals the EPA has banned from industrial manufacturing, yet it is still produced as a byproduct in many plants. And maybe its longevity is a warning. An effort is underway in Congress to update the Toxic Substances Control Act, which governs human-created chemicals. When it was passed in 1976, it grandfathered in tens of thousands of chemicals, meaning none of them had to be approved for safety. Now there's a push to shift the burden to industry, to make manufacturers prove that chemicals are safe before they're created on a big scale.
