Abstract:

This dataset contains air quality data (ozone and PM 2.5) and population data. Ozone indicators calculated from this dataset include days and person-days above benchmark. PM2.5 indicators include mean concentration, percent of days and person-days over benchmark and percent of population in monitored counties over benchmark.

Purpose:

The purpose of the Oregon EPHT Program is to provide scientific information from a web-based network of hazard, exposure, and health effect data to support actions that improve the health of communities. By bringing together, and standardizing, local, state, and national data sources of environmental and health information, scientists, policymakers, and the public will be able to more effectively address fundamental questions about relationships between environmental exposures and health effects.

The Oregon EPHT Program is part of a National EPHT Network sponsored by the CDC. The Oregon EPHT Program resides in the Research & Education Section of the Office of Environmental Public Heath (OEPH) which is in the Public Health Division of the Oregon Health Authority.

Supplemental information:

The Oregon EPHT indicators are calculated from data obtained from the U.S. Environmental Protection Agency and the U.S. Census Bureau.

Dataset overview:

The Oregon EPHT Air Quality dataset contains information on PM 2.5 and ozone levels.The PM2.5 and ozone indicators use EPA air quality data from ambient air monitors and the methodology described in the National EPHT Air Team's indicator report (www.cdc.gov/nceh/tracking/default.htm). 

The dataset contains (for each county having complete monitoring data): the year, county name, county population, number of days by county above ozone benchmark, the person-days by county above ozone benchmark, county PM2.5 annual mean, percent of monitored days above benchmark, and the number of person-days above benchmark.

Benchmarks used are the Federal National Ambient Air Quality Standard (NAAQS).
