Previous Kilauea gas risks studied

 •  Fumes, winds keeping Volcanoes park closed

People exposed to sulfur pollution from Kilauea volcano report higher rates of sore throats, runny noses and coughs, according to a recently released study.

The study of 335 people also found faster pulse rates and higher blood pressure among exposed groups, said Bernadette Longo, one of the authors of the study and a professor of nursing at the University of Nevada-Reno.

"As far as I know, this is the first study that looks at the health effects of volcanic air pollution exposure on the heart and lungs anywhere in the world," Longo said by telephone yesterday.

Elevated sulfur dioxide levels from the volcano prompted closure of Hawai'i Volcanoes National Park for the second straight day yesterday. The National Park Service said air conditions were worse than on Tuesday, when 2,000 people were evacuated from the park.

Hawai'i health officials counsel residents who have respiratory conditions such as asthma or are exposed to sulfur pollution for prolonged periods to take precautions: They should stay indoors and use air conditioners, not smoke, drink warm fluids to loosen mucus and limit physical exertion.

The Department of Health also recommends people keep an adequate supply of any medication they are taking on hand. Health officials say people should contact their physicians if they develop any respiratory problems.

"I'm really concerned that parents of asthmatic children are vigilant," said Beth-Ann Kozlovich, director of development for the American Lung Association of Hawai'i.

Longo's study, which was conducted in 2004 and released in February, included residents living in two areas of the Big Island — one exposed to sulfur pollution in the Ka'u District and an unexposed group in Hawi.

Longo said her work confirms the findings of other research about sulfur dioxide and particulate matter.

Longo said she wants to work with clinicians in the area to encourage residents to take their medications and help them quit smoking, both of which she said can affect blood pressure.
