• Grass Pollen Total: Decreased by 41% from 34 to 20.

• Weed Pollen Total: Increased by 100% from 12 to 24.

• Overall Tree, Weed, Grass Pollen Total: Increased by 44% from 82 to 118.

Mold:

• Overall Mold Total: Increased by 53% from 7,324 to 11,190.

Specific Species Changes:

• Carya (Hickory/Pecan): Increased by 425%.
