Description (Provided by Applicant) The long-term objective of this program is to develop the capacity of the Hawaii Island community to design, conduct, interpret, and disseminate research on the health effects of volcanic air pollution. Kilauea's volcano's continuous sulfur dioxide (SO2) emissions for more than 20 years, characteristic island wind patterns, and Hawaii's towering mountains create a natural experiment in which some communities are almost chronically exposed to SO2, some acid aerosols, and some communities to virtually no volcanic air pollution. Together with academic partners and community advocates, the Hawaii Island Children's Lung Assessment Scientific Study (HICLASS), community researchers will continue their school based-longitudinal study of a cohort of 1,988 Hawaii Island schoolchildren who have lived in these different zones of volcanic air pollution. Extending the longitudinal study another 5 years will help identify differences in incident asthma and the rate of lung growth, a particularly sensitive measure of respiratory health. In addition, HICLASS researchers will address the environmental exposure and respiratory health effects of students of the Volcano School of Arts and Sciences. This school of 140 students is within two miles of Kilauea's Halemaumau Center and 10 miles of Pu'u O'o vent. During periods of low wind speed or winds from the south, the students may be exposed to SO2concentrations in excess of 500 ppbv. Very recently, SO2 emissions from Halemaumau have increased from 100 tons/day to almost 1000 tons/day, providing a unique opportunity to learn the determinants and health effects of episodes of SO2 in excess of 1000 ppbv. In addition to including VSAS in its air monitoring program and school-based health assessments, HICLASS will facilitate pilot projects and reports by students to test factors that ameliorate exposure or acute health effects.

描述（申请人提供） 该方案的长期目标是发展夏威夷岛社区设计、进行、解释和传播关于火山空气污染对健康影响的研究的能力。 基拉韦厄火山20多年来持续排放二氧化硫（SO2），特有的岛屿风模式，以及夏威夷高耸的山脉创造了一个自然实验，其中一些社区几乎长期暴露于SO2，一些酸性气溶胶，而一些社区几乎没有火山空气污染。与学术合作伙伴和社区倡导者一起，夏威夷岛儿童肺部评估科学研究（ELASS），社区研究人员将继续对居住在这些不同火山空气污染区的1，988名夏威夷岛学童进行基于学校的纵向研究。 将纵向研究再延长5年将有助于确定哮喘发病率和肺部生长速度的差异，这是一种特别敏感的呼吸系统健康指标。 此外，研究人员还将研究火山文理学院学生的环境暴露和呼吸健康影响。这所拥有140名学生的学校距离基拉韦厄的Halemaumau中心不到两英里，距离Pu 'u O 'o火山口不到10英里。在低风速或南风期间，学生可能会暴露在SO2浓度超过500 ppbv的环境中。最近，Halemaumau的SO2排放量从100吨/天增加到近1000吨/天，为了解SO2超过1000 ppbv的决定因素和健康影响提供了独特的机会。除了将VSAS纳入其空气监测方案和以学校为基础的健康评估外，该系统还将促进试点项目和学生报告，以测试改善暴露或急性健康影响的因素。
