DOH Guidance on Short-term Sulfur Dioxide (SO2) Advisory Levels
Due to sulfur dioxide emissions from the Kilauea Volcano on Hawaii Island, monitors provide readings of gas levels every 15-minutes (compared to hourly averages at other monitoring sites across the state). This chart provides health guidance based on the current air quality in areas nearby.
Air Quality Index (AQI) Basics
The Air Quality Index, or AQI, is an index for reporting daily air quality. It explains how clean or polluted the air is, and what associated health effects might be a concern. The AQI focuses on health effects a person may experience within a few hours or days after breathing polluted air. The U.S. Environmental Protection Agency (EPA) calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide.
Federal and State Ambient Air Quality Standards
The U.S. Environmental Protection Agency (EPA) sets National Ambient Air Quality Standards (NAAQS) to protect public health and welfare from harmful effects of certain commonly occurring pollutants known as “criteria” pollutants.
