What's with the smell?

Health, Odors, & Air Quality Survey

In response to health concerns of residents in and around Carson, CA in Fall of 2021, we launched a health survey to assess short and longer-term impacts of the odors and hydrogen sulfide concentrations.  The survey can be completed online in 20-30 minutes and participants will receive a $10 gift card for their time. Adult residents (18 years or older) of the Carson area may email or call 323-647-7564 for more information. Summary findings will be shared with participants and the community. Below we share resources and epidemiological studies on the health effects associated with exposure to hydrogen sulfide. 

Have you lived in this area for 6 months or longer?

Ha vivido en esta área por 6 meses o más?

Si has vivido alrededor de Carson por 6 meses o más Y eres major de 18 ańos, te invitamos a participar en nuestro estudio!
