A top grade is 3.2 high-particle days during a year.The Las Vegas-Henderson metro area ranked 11th worst in the nation for ozone pollution. The ranking was based on the area’s worst county’s average number of unhealthy days—22.3 days per year, an F grade, in Clark County. This was worse than the area’s ranking in last year’s report of 12th worst, with 22.2 days per year, an F grade.Washoe County also received an F grade for high particle days, showing much the same pattern as Douglas County. It also had a grade of C for high ozone days, something that didn’t any data for Douglas. Washoe received a passing grade for annual pollution.</div></body>
