PHOENIX -- Getting the dirt on the Phoenix-Scottsdale area apparently is easier than imagined.
Travel and Leisure magazine has rated that area No. 19 on its dirtiest U.S. cities list.
Magazine editors' criteria included trash collection, rodent population and reader feedback.
Phoenix's venture into the top 20 got a push from its spot on the American Lung Association's list of most air-polluted cities.
New York City was No. 1 in grime, followed by New Orleans, Baltimore, Los Angeles and Atlanta.
