HONOLULU, Hawaii - State health officials are warning Big Island residents of elevated levels of sulfur dioxide caused by the volcanic activity at Kilauea.

The Health Department is monitoring sulfur dioxide levels in Kona, Hilo, Mountain View, Pahala and Pahoa.

Elevated levels of sulfur dioxide could cause breathing problems, especially those with respiratory conditions such as asthma, emphysema and bronchitis.

The American Lung Association recommends staying indoor and using an air conditioner, drinking plenty of liquids and calling the doctor as soon as respiratory problems develop.
