Health, Odors, and Air Quality Carson Study
What’s with the smell?
In response to health concerns of residents in and around Carson, CA in Fall of 2021, we launched a health study to assess short and longer-term impacts of the odors and hydrogen sulfide concentrations. Adult residents (18 years or older) of the Carson area are eligible for the study and may email ejresearchlab@usc.edu or call 323-647-7564 for more information. Summary findings will be shared with participants and the community. See below for resources and information on hydrogen sulfide.
