Some US Cities Plagued with Double Whammy of Allergens
Live Science reporter Rachael Rettner has recently reported that Some US cities are riddled both with high ozone levels and ragweed pollen. This results in a double whammy situation very much unfavorable for allergy sufferers in these cities.

The top cities with this allergy-inducing combo — dubbed in the report as the “Sneeziest and Wheeziest” cities — include Richmond, Virginia; Memphis, Tennessee; Oklahoma City; Philadelphia; Chattanooga, Tennessee; and Chicago, according to the report, from the National Resources Defense Council (NRDC), an environmental advocacy group based in New York.
The report is one of the first to identify the areas that have both high ozone levels and ragweed pollen. Overall, 109 million Americans live in these areas, the report found. Either ozone smog or ragweed pollen by themselves can trigger allergy symptoms and asthma attacks, but people who are exposed to both tend to become more ill than people who are exposed to only one of these triggers, the NRDC says.
What’s more, the rising temperatures expected to come with climate change could increase both ozone production and pollen levels, worsening people’s allergies, the NRDC says. Other cities that made the top-10 list of the Sneeziest and Wheeziest were Detroit; New Haven, Connecticut; Allentown, Pennsylvania; and Atlanta.
