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：城市环境正义社区在重大事件发生后的健康症状和风险认知 硫化氢灾难 抽象的 2021 年 10 月，洛杉矶县南湾地区卡森及附近社区的居民， 加州开始报告有强烈的恶臭、头痛、恶心和呼吸困难。突然和 硫化氢（H2S）（一种有毒气味气体）浓度的持续飙升被确定为来源， 影响着南湾成千上万居民的生活质量和健康。在峰值时，H2S 含量达到 超过十亿分之 7000——加州一小时环境空气质量标准 30 的 230 倍 每十亿分之一——但 H2S 浓度在 6 周内保持较高水平。虽然周围有大量文献 硫化氢暴露的严重影响、恶臭灾难后对健康的影响 像这样的城市环境正义社区的特征并不明确。在这个项目中，我们的目标是 1) 推进 通过参与式研究提高社区教育和研究能力； 2) 表征氢 使用密集的固定网络在空间和时间上分析卡森和邻近城市的硫化物暴露情况 监视器； 3) 检查 H2S 暴露与 (a) 健康症状、睡眠质量、精神状态之间的关联 使用经过验证的调查工具进行健康和气味体验； (b) 测量心肺功能 南湾居民纵向队列的结果； 4) 了解期间和之后的经历 灾害及其与生活质量、不稳定、压力源和脆弱性的关联——以及灾害如何影响 通过半结构化塑造风险认知、应对策略和获取健康保护资源 采访。这项时间敏感的工作的成果将填补了解恶臭影响的关键空白 和 H2S 暴露事件对弱势群体的社区健康症状和福祉的影响 参与式研究。这项研究的结果也可用于增进理解和沟通 恶臭和硫化氢释放对其他社区的影响。
