In October 2021, hydrogen sulfide (HS), a toxic odorous gas, was measured in Carson, California at concentrations reaching 7000 parts per billion (ppb), exceeding California’s 30 ppb acute air quality standard. Thousands of residents complained of malodors and headaches. We responded to community concerns by launching a rapid survey assessing symptoms. We recruited participants through door-to-door outreach, community events, and social media. During the emergency’s first week, 75% of the 108 total respondents experienced headaches, 72% experienced dizziness, and 63% experienced difficulty sleeping. About 60% of respondents ( = 63, no response = 7) noted the odor worsening their mental health. When adjusting for age, sex, and smoking, participants <2 km from the highest HS concentrations reported higher prevalence of agitation (PD = 0.23, 95% CI: 0.03, 0.42) and headaches (PR = 0.14, 95% CI: −0.04, 1.31) compared to participants farther away. Malodors are underprioritized in environmental justice communities, despite HS’s effects on mental and physical health.
2021年10月，在加利福尼亚州卡森市检测到有毒恶臭气体硫化氢（HS），浓度达到十亿分之7000，超过了加利福尼亚州30 ppb的急性空气质量标准。数千名居民抱怨有恶臭和头痛症状。我们通过开展一项快速调查来评估症状，以回应社区的担忧。我们通过挨家挨户宣传、社区活动和社交媒体招募参与者。在紧急情况的第一周，108名总受访者中有75%经历了头痛，72%经历了头晕，63%经历了睡眠困难。约60%的受访者（n = 63，无回应 = 7）指出气味使他们的心理健康恶化。在对年龄、性别和吸烟情况进行调整后，与距离较远的参与者相比，距离最高HS浓度<2公里的参与者出现烦躁不安（PD = 0.23，95% CI：0.03，0.42）和头痛（PR = 0.14，95% CI：-0.04，1.31）的患病率更高。尽管HS对身心健康有影响，但在环境正义社区中，恶臭问题未得到足够重视。
