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：重大事故后城市环境正义社区的健康症状和风险感知 硫化氢灾害 摘要 2021年10月，洛杉矶县南湾地区卡森及附近街区的居民， 加州开始报告强烈的恶臭，头痛，恶心和呼吸窘迫。一次突然和 硫化氢（H2S）浓度的持续飙升，一种有毒的气味气体，被确定为来源， 影响了南湾数千居民的生活质量和健康。在其高峰期，H2S水平达到 超过十亿分之7000--是加州一小时环境空气质量标准的230倍 但H2S浓度持续升高6周。虽然有大量的文献 硫化氢暴露的严重影响，恶臭灾难后的健康影响， 像这样的城市环境正义社区并没有很好的特征。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，在卡森和邻近城市的空间和时间上的硫化物暴露 3）检查H2S暴露与（a）健康症状、睡眠质量、心理健康、 健康和气味体验;和（B）用测量的心肺功能 南湾居民的纵向队列的结果;和4）了解期间和之后的经验， 灾害及其与生活质量、不稳定性、压力源和可持续性的关系，以及灾害如何影响 通过半结构化的方式塑造风险认知、应对策略和获得健康保护资源的途径 采访这项时间敏感的工作的结果将填补理解恶臭影响的关键空白 和H2S暴露事件对社区健康症状和弱势群体福祉的影响， 参与式研究。本研究的结果也可用于改善理解和沟通 恶臭和硫化氢排放对其他社区的影响。
