The phrase "air pollution values" is correct and usable in written English.
It can be used when discussing measurements or data related to the levels of pollutants in the air.
Example: "The report highlighted the air pollution values recorded over the past year, indicating a significant increase in harmful emissions."
Alternatives: "air quality metrics" or "pollutant concentration levels".
Air pollution values were linked to schools using the schools' postal codes.
On average 8,314, 8,148, and 8,248 hourly air pollution values were available to estimate annual averages for CO, NO2, and O3, respectively.
There may have been a bias in exposure estimation since housing in high poverty areas may be situated closer to traffic, yet neighborhoods with high and low poverty levels were assigned the same air pollution values.
Our results show that GAMs with a combination of spatial smoothing and GIS-derived covariates are a practical method for predicting annual outdoor air pollution values for a cohort dispersed across the continental United States.
Various techniques (e.g. inverse distance weighting, land use regression analysis and geo-statistical methods such as kriging) have been developed to interpolate air pollution values at the locations where data are unavailable using data collected at multiple sites [ 16, 17].
But since for each model there were many different sized cars, we used the fuel efficiency and air pollution values based on the vehicle that had the median fuel efficiency within the range for that model (using the same data sources as for the advertised vehicles).
Daily PM10 levels were calculated from publicly available air pollution index values (Shenyang Environmental Bureau 2007) based on the guidelines provided by the China National Environmental Monitoring Center (2007).
Specifically, we considered air pollution RR values of 1.01, 1.05, 1.10, 1.15, and 1.20 representing the increase in outcome (y) associated with an incremental increase in a given pollutant exposure equal to the level of the average value of the ambient pollution concentration (c) in the study population.
We used daily pollutant levels in each county to compute the mean air pollution concentration value for the 6-week period preceding each day of observation.
Trees are a valuable economic asset... play an important role in energy conservation... reduce air pollution... increase property values... attract business....".. And so forth.
The present daily time-series analysis examines the effects of day-to-day differences in air pollution, not absolute values.
