PM2.5 annual mean (NAAQS 9 µg/m³ (annual))iHealth riskFine inhalable particles 2.5 micrometers or smaller. They travel deep into the lungs and into the bloodstream — linked to asthma, heart disease, stroke, and premature death.

5.89 µg/m³ · -34% YoY · -50% since 2011

PM2.5 annual mean (NAAQS 9 µg/m³ (annual)) concentrations have more than halved since 2011.

PM2.5 24-hour 98th percentile (NAAQS 35 µg/m³ (24-hour))iHealth riskFine inhalable particles 2.5 micrometers or smaller. They travel deep into the lungs and into the bloodstream — linked to asthma, heart disease, stroke, and premature death.

15.80 µg/m³ · -64% YoY · -48% since 2011

PM2.5 24-hour 98th percentile (NAAQS 35 µg/m³ (24-hour)) concentrations have fallen 48% since 2011.

Ozone 8-hour 4th-highest daily max (NAAQS 0.070 ppm (8-hour))iHealth riskGround-level ozone (smog) forms when vehicle and industrial emissions react in sunlight. Inflames the airways, triggers asthma attacks, and worsens heart and lung disease.

0.066 ppm · -3% YoY · -18% since 2010

Ozone 8-hour 4th-highest daily max (NAAQS 0.070 ppm (8-hour)) concentrations have fallen 18% since 2010.

NO₂ annual mean (NAAQS 53 ppb (annual))iHealth riskA tailpipe and combustion gas. Concentrates near busy roads and industrial sites; raises risk of airway inflammation, asthma, and lower respiratory infections in children.

Single-vintage exposure modeling — EPA cadence is multi-year, so no trend line yet.

Lifetime cancer risk all pollutants (100 in a million (EPA elevated threshold))iHealth riskEPA-modeled added cancer cases per million residents from a lifetime of breathing local air toxics. EPA flags 100-in-a-million as elevated.

Greenhouse gases (GHGRP large emitters, through 2023)iHealth riskGreenhouse gases reported by large industrial emitters under EPA's GHGRP, in metric tons of CO₂ equivalent. Drives climate warming and the heat-related health effects that follow.

0.0M metric tons CO₂e · +4% YoY · -92% since 2010

Greenhouse gases (GHGRP large emitters, through 2023) concentrations have more than halved since 2010.
