Rochester's air quality in New York benefits from Lake Ontario's consistent lake winds providing natural ventilation along the southern shore, with the primary concerns being vehicle emissions from I-490 and the legacy of Eastman Kodak and Xerox industrial emissions from the Genesee River valley. Winter lake-effect snow events effectively wash particulates from the atmosphere, while summer Great Lakes ozone periodically elevates readings.
