CARSON — The Los Angeles County Department of Public Health or Public Health and Public Works are investigating odors reported in the City of Carson. The South Coast Air Quality Management District (SCAQMD) notified Public Health of an odor event in Carson Oct. 7, and advised that their investigation ruled out a point source or permitted business as the source of the odor.
Public Health conducted air monitoring Oct. 8 and 9, and reported finding very low levels of hydrogen sulfide in the air (0.4-0.9 ppm) east of the Dominguez Channel. At these levels, public health stated hydrogen sulfide does not have long-term health effects, but does cause nuisance odors that may cause short-term symptoms and impact quality of life. Some residents may experience temporary symptoms such as headaches, nausea, or eye, nose, and throat irritation. Symptoms should go away when the odors are no longer present.
If residents are experiencing persistent symptoms from the odors, they are encouraged to contact their health care providers, especially if they have any chronic health conditions. Residents should also ensure that they have adequate supplies of their medications, especially if they have heart or lung conditions.
Local officials are continuing to work to identify the source of the odor. Until the odor event subsides, Public Health recommends preventing outdoor odors from entering the home by keeping doors and windows closed as much as possible while odors are present. Public Health also recommends using an air conditioner, if available. Residents can also use a portable indoor air filter such as a High Efficiency Particulate Air (HEPA) cleaner to improve air quality in their home.
For more information on certified air filters, visit the California Aire Resources Board.
Residents should continue to call AQMD to report odors. 1-800-CUT-SMOG (1-800-288-7644).
