The Air Quality Aware app is intended to provide information about the current conditions of air quality in the United States, along with the potential human health impacts. The data shown here from the Living Atlas are authoritative U.S. government sources, including:The Environmental Protection Agency AirNow program for current and future Air Quality Index information.The NOAA National Weather Service wind forecast.U.S. Census - derived  American Community Survey demographic data.Air quality stations and "Current" conditions update hourly. Forecasts "Today" and "Tomorrow" are generated once a day, usually in the late afternoon, local time. While some areas of Canada and Mexico have air quality information displayed, forecast air quality, winds, and demographic information are only available in the USA. 

Ambient monitoring measures the status of air quality throughout the state to assess trends, compliance with federal and state air quality standards, effectiveness of control strategies and attainment plans, health effects and environmental damage; respond to citizen complaints; evaluate specific geographic or hot-spot air quality concerns; and create environmental indicators. Emission inventory is the cataloging of sources of air pollution and the emissions from those sources. Inventory data are critical to the understanding of the causes of air pollution problems and creation of appropriate solutions. Meteorological forecasting and dispersion modeling of air pollutants are essential to understanding the movement and buildup of air pollution; the carrying capacity of airsheds; the interaction of pollutants; and the location of maximum impact of sources of pollution. As of September 26, 2005 there are no longer any areas of Washington designated as "NONATTAINMENT."

Although many volatile organic compounds (VOCs) are regulated to limit air pollution and the consequent health effects, the photooxidation products generally are not. Thus, we examined the mutagenicity in Salmonella TA100 of photochemical atmospheres generated in a steady-state atmospheric simulation chamber by irradiating mixtures of single aromatic VOCs, NOx, and ammonium sulfate seed aerosol in air. The 10 VOCs examined were benzene; toluene; ethylbenzene; o-, m-, and p-xylene; 1,2,4- and 1,3,5-trimethylbenzene; m-cresol; and naphthalene. Salmonella were exposed at the air-agar interface to the generated atmospheres for 1, 2, 4, 8, or 16 h. Dark-control exposures produced non-mutagenic atmospheres, illustrating that the gas-phase precursor VOCs were not mutagenic at the concentrations tested. Under irradiation, all but m-cresol and naphthalene produced mutagenic atmospheres, with potencies ranging from 2.0 (p-xylene) to 10.4 (ethylbenzene) revertants m3 mgC-1 h-1. The mutagenicity was due exclusively to direct-acting late-generation products of the photooxidation reactions. Gas-phase chemical analysis showed that a number of oxidized organic chemical species enhanced during the irradiated exposure experiments correlated (r ≥ 0.81) with the mutagenic potencies of the atmospheres. Molecular formulas assigned to these species indicated that they likely contained peroxy acid, aldehyde, alcohol, and other functionalities.

This study was performed to determine the role of adrenal-derived stress hormones in mediating brain effects after ozone exposure. Sham and adrenalectomized rats were exposed to air or ozone for 4 hours and within 2 hours after exposure brain regions, hypothalamus and brainstem were isolated and circulating pituitary hormones were analyzed. Global gene expression was analysed in these two brain regions using Illumina mRNA sequencing platform and data were analyzed using various bioinformatics platforms. The resulting data are included in this manuscript. This dataset is associated with the following publication: Henriquez, A., J. House, S. Snow, C. Miller, M. Schladweiler, A. Astriab Fisher, H.

Concentrations of 11 species are reported from continuous measurements taken during a wintertime field study in Utah. Time series data for measured species generally displayed strong diurnal patterns. Six species show a diurnal pattern of daytime maximums (NO, NOy, O3, H2O2, CH2O2, and Cl2), while five species show a diurnal pattern of night time maximums (NO2, HONO, ClNO2, HNO3, and N2O5). Vector autoregression analyses were completed to better understand important species influencing the formation of O3 and NOx. For the species studied, r2 values of predicted versus measured concentrations ranged from 0.82–0.99. Fitting parameters for the autoregressive matrix, Pi, indicated the importance of species precursors. In addition, values of fitting parameters for Pi were relatively insensitive to data size, with variations generally <10%. Variable causation was quantified using the Granger causation method. Assuming O3 and NOx behave as chemical products, reactants (in order of importance) are as follows: H2O2, N2O5, HONO, and ClNO2.
