So before you run out and fill your house with plants – remember the photos of the plants over in Puna that yellowed in response to the sulfur dioxide? That confirms sulfur dioxide’s is poisonous to plants at high concentrations and while plants will remove low levels of SO2 from the air, the typical house in Hawaii is not sealed up like a house in upstate New York and is going to be getting steady supply of high concentrations of SO2 to absorb so it is going to take a lot of plants processing a lot of SO2 to keep the air in your house clean. Given the concentrations of SO2 in some areas, house plants could just as easily die like the plants we saw near the fissures. The other thing is that a lot of Hawaiian houses aren’t air conditioned so closing up the house just might not be possible. It would be great if we could mitigate this situation but we are in the middle some extreme conditions and attempts at mitigation may be akin to trying to boil the ocean. Sadly it is likely the only way to avoid exposure is to remove yourself from the conditions.
