What we're looking at: Erupting volcanoes spew hazardous sulfur dioxide gas. If conditions are right, that gas and other pollutants can settle with moisture and dust to create a haze called volcanic smog, or "vog," with tiny sulfuric acid droplets.If it rains when it's voggy, you get acid rain.What causes it: We've had vog already, but mostly south of the island over the ocean, because trade winds have largely been keeping it away.But the winds are expected to calm down Thursday and Friday, possibly allowing the vog to settle over more of the island.It should rain over the Big Island on Thursday into Saturday. The vog's sulfuric acid droplets would fall, too -- thus, acid rain.How it impacts people: Vog seems to be the more immediate health concern. At higher concentrations, vog can cause headaches and irritation to the lungs and eyes, the University of Hawaii at Hilo saysHigh levels of acidic particles in vog "can induce asthma attacks, especially in adolescents, and can also impede the ability of the upper respiratory tract to remove other potentially harmful particles," the USGS says.For people with asthma and other respiratory problems, "the effects are much more serious, causing a tightening of the airways in the lungs and making it very difficult to breathe," the university says.But it adds: "There's been no clear evidence that vog causes lingering damage to normally healthy individuals."How acid rain affects human health is more complicated.Walking in acid rain or swimming in a lake affected by it "is no more dangerous to humans than walking in normal rain or swimming in non-acidic lakes," the Environmental Protection Agency says.But acid rain can contaminate household water supplies by leaching metals from building and plumbing materials, the USGS says. That includes rooftop rainwater-catchment systems that Hawaii residents use for drinking water. 1912
