Our traditional northwest winds that accompany a frontal passage send “whiffs” to us that are either pleasant or offensive. The paper mills in the Felicianas eject a smell that reminds me of the Heinz plants in Pittsburgh. Flowers Baking Company on Florida Blvd. sends an aroma that reminds me of Mom’s kitchen. A south wind advances the odor from the treatment plant near River Road. In Irwindale, CA. Huy Fong Foods manufacture Sriracha, a spicy Asian hot sauce. The production of the sauce can release a variety of odors from garlic, peppers and vinegar. Some residents don’t like it, others don’t mind it. Environmental scientists have been monitoring the odors at numerous locations. A good wind can move the “smell” or provide the aroma.
