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

We can fix it and keep it out of the landfill, said Gleason.According to the Equinox Project, the average San Diegan tosses out five and a half pounds of trash every day, including stuff that just isn't working.  Two items that didn't end up in the trash were Warth's speakers."They sautered it and put in a little piece of tape to separate the wires, so there was no shortage.  I plugged it in and it worked," said Warth.Zero Waste San Diego is also looking for new venues for future clinics.if you have a suggestion or want more information on the free clinics, visit Zero Waste San Diego. 616

Water and gas service had been restored at the base, but engineers were ensuring buildings were safe to enter. The shaking cracked walls in a chapel and school and brought down commissary shelves, Allen said. 208

What is toxic algae?Algae occurs naturally in water, but the blue-green variety are considered Harmful Algal Blooms (HABs). Blue-green algae, also known as cyanobacteria, are "primitive," photosynthetic organisms that can feed off the sun to make their own energy and release oxygen and possibly toxins in the process, said 324

Under the proposal, school staff members who could be armed must complete 144 hours of training and meet other criteria. The program would be voluntary, implemented only if the sheriff's department and school district agree. School personnel would not be required to participate. 279
