TITLE: Health symptoms and risk perception of urban environmental justice communities after major hydrogen sulfide disaster ABSTRACT In October 2021, residents of Carson and nearby neighborhoods in the South Bay area of Los Angeles County, California began reporting strong malodor, headaches, nausea, and respiratory distress. A sudden and persistent spike in the concentrations of hydrogen sulfide (H2S), a toxic odorant gas, was identified as the source, affecting the quality of life and health of thousands of residents in the South Bay. At its peak, H2S levels reached upwards of 7000 parts per billion—230 times the California’s one-hour ambient air quality standard of 30 parts per billion—but H2S concentrations remained elevated for 6 weeks. While there is a body of literature surrounding the acute impacts of hydrogen sulfide exposures, health effects in the aftermath of a malodorous disaster in an urban environmental justice community like this are not well characterized. In this project, we aim to 1) Advance community education and research capacity through engaged participatory research; 2) Characterize hydrogen sulfide exposures in Carson and neighboring cities over space and time using a dense network of stationary monitors; 3) Examine the association between H2S exposure with (a) health symptoms, sleep quality, mental health, and odor experience using validated survey instruments; and (b) with measured cardiopulmonary outcomes across a longitudinal cohort of South Bay residents; and 4) Understand experiences during and post- disaster and their association with quality of life, precarity, stressors, and vulnerabilities—and how disaster shapes risk perception, coping strategies, and access to health protective resources through semi-structured interviews. Outcomes from this time-sensitive work will fill a critical gap in understanding the effects of malodor and H2S exposure events on community health symptoms and well-being in vulnerable populations through participatory research. Results from this study may also be used to improve understanding and communication of impacts of malodors and hydrogen sulfide releases in other communities.

标题：主要之后的城市环境正义社区的健康症状和风险感知 硫化氢灾难 抽象的 2021年10月，卡森（Carson）和附近社区的居民位于洛杉矶县南湾地区 加利福尼亚开始报告强烈的恶意，头，恶心和呼吸窘迫。突然 持续的硫化氢浓度（H2S）（一种有毒的气形气体）被确定为源 影响南湾成千上万居民的生活质量和健康。达到顶峰，H2S水平达到 超过7000份的零件，加利福尼亚一小时的30份环境空气质量标准为230倍 每十亿美元，但H2S浓度持续6周。虽然周围有很多文献 硫化氢暴露的急性影响，在发生恶劣灾难后的健康影响 像这样的城市环境正义社区没有很好的特征。在这个项目中，我们的目标是1） 通过参与研究的社区教育和研究能力； 2）表征氢 卡森和邻近城市在空间和时间上使用硫化物暴露，使用固定的密集网络 监视器； 3）检查H2S暴露与（a）健康症状，睡眠质量，心理 使用经过验证的调查工具的健康和气味经验； （b）用测量的心肺 南湾居民的纵向队列的结果； 4）了解期间和之后的经验 灾难及其与生活质量，偏见，压力源和脆弱性的联系，以及如何灾难 通过半结构化塑造风险感知，应对策略和获得健康保护资源 访谈。这项时间敏感的工作的结果将填补理解恶性肿的影响的关键空白 和H2S暴露于社区健康症状和脆弱人群中的幸福感 参与研究。这项研究的结果也可以用来改善理解和交流 其他社区中疾病和硫化氢释放的影响。
