Air Pollutants by Borough
PM2.5 (μg/m³) · NO₂ (ppb) · O₃ (ppb) · NYCCAS
ℹWhy this matters▸
NO₂ comes primarily from vehicle exhaust and building boilers. Long-term exposure worsens asthma and increases cardiovascular risk.
PM2.5 Annual Trend (Citywide)
Fine particulates μg/m³ · WHO guideline = 5
PM2.5 by Neighborhood
Annual μg/m³ · NYCCAS · WHO guideline = 5
ℹWhy this matters▸
PM2.5 is fine particulate matter that penetrates deep into your lungs. The WHO recommends below 5 μg/m³ — every NYC neighborhood exceeds that guideline.
