The lead isn't a component of the vog.
It's the acidic rain that leaches lead out of everything it touches.
From USGS:
Many homes on the Island of Hawai`i rely on rooftop rainwater-catchment systems to provide their drinking water. In 1988, the drinking water of nearly 40% of homes using such systems in the Kona Districts of the island was found to be contaminated with lead leached by acid rain from roofing and plumbing materials, such as nails, paint, solder, and metal flashings.
