Investigation of powder in air reveals it was pollen

CHARLESTON, W.Va. (AP) — West Virginia officials investigating reports of a powder in the air and on some vehicles in the mid-Atlantic have determined the source: pollen. The West Virginia Department of Environmental Protection said in a statement Monday that final results from the dust samples collected Friday in the state’s Eastern Panhandle indicated the material is predominantly pollen, with trace amounts of mineral matter. The agency began investigating after residents reported seeing the substance across multiple counties late Thursday night. Social media users posted about seeing the powder in the air and on cars on Friday in West Virginia, northern Virginia and Maryland.
