West Sacramento fire officials were unable to identify the cause of an odor that sent one person to the hospital early this afternoon.
Acting Battalion Chief Scott Pfeifer said that about noon, employees of businesses in an industrial park area along Riverside Parkway and Reed Avenue reported an ammonia-like smell that caused some people to complain of respiratory problems.
When firefighters arrived, the odor had dissipated. Pfeifer said fire crews spent about an hour contacting businesses in the area but were unable to locate the source of the odor.
He said an employee of one area business was taken to a hospital after complaining of feeling ill.
