“Nevertheless, the concentration recorded post-smoking ban was 240.8 μg/m3, which is still almost 7 times the NAAQS.”

Structure

Source: Tobacco smoke (secondhand smoke)
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: hospitality venue, IN
Study design: before-and-after measurement study of public venues in Mumbai: fine particulate matter measured in restaurants, bars, hookah parlours and control locations before and after the comprehensive smoking ban came into force (class 4)
Effect: mean 240.8
Caveat: a concentration measured after the ban across the venues, not the change itself
