The phrase "air quality values" is correct and usable in written English.
It can be used when discussing measurements or assessments related to the quality of air in a specific area or environment.
Example: "The report indicated that the air quality values in the city have improved significantly over the past year."
Alternatives: "air quality measurements" or "air quality indicators".
Because daily readings were taken at various locations throughout the region, the arithmetic means of the air quality values were used as exposure variables.
Certain analytical choices have a particularly strong influence on the temporal and spatial distribution of air quality values observed in epidemiological studies.
To calculate the air quality values under each attainment scenario, we rolled back the ozone monitor data so that the fourth highest daily maximum 8-hr average just met the level required to attain the standard.
With the increase of the air quality index values, the hypertrophic index values in both towns rose.
Twenty-nine infringement cases are currently underway in 20 member states for failure to comply with EU air quality limit values, and approximately two thirds of member states are currently in non-compliance with PM10 and NO2 limit values; one in five exceed the PM2.5 target value.
Inclusion of study designs unlisted in the SIGN grading system did not bring additional evidence regarding exposures below the current air quality limit values for NO2.
The residential wood combustion contribution to PM10 air quality concentration values during January 2007 ranges from 0 to 14 μg m−3, with a mean contribution of 10 μg m−3 in the Lisboa area and 6 μg m−3 in the Porto region.
Effects were observed in study populations with exposures that were well below the current European air quality limit values (European Commission 2013).
Although there was considerable day-to-day variability in air quality, daily values across monitoring sites were highly correlated across the city (mean Pearson's correlation coefficient = 0.90; range, 0.83 0.94); data are shown for a single monitoring station.
With the average concentrations experienced in households being significantly higher than health-based air quality guideline values, the results from the study indicate the need for achieving substantive exposure reductions for the population.
Household air pollution concentrations (including outdoor concentrations in communities affected by inefficient biomass and coal combustion emissions) are consistently much higher than the annual WHO air quality guideline values and, in most instances, exceed the higher 24-hr interim target guideline concentrations.
