The phrase "air concentration" is correct and usable in written English.
It can be used in contexts related to environmental science, chemistry, or air quality measurements, referring to the amount of a substance present in the air.
Example: "The air concentration of pollutants in the city has increased significantly over the past decade."
Alternatives: "atmospheric concentration" or "airborne concentration".
The results show that, with the air concentration of aerated jet-flow increasing, the impact pressure increases before the air concentration reaches 2.43% and decreases after the air concentration exceeds 2.43%.
However, air concentration in the surrounding environment of non-hazardous waste landfill sites is poorly documented.
The indoor to outdoor air concentration ratios were comparable with previous studies.
Computer aided methods for comparing alternative process concepts based on fugitive emission and occupational air concentration were developed.
The cementitious photocatalytic material showed an interesting photocatalytic activity with linear dependence versus pollutant air concentration and irradiance.
The increased dissolved air concentration in water at elevated pressure is the fundamental principle that allows the formation of microbubbles.
This study found that temperature and benzene air concentration affected the untreated product water from a CWFA system.
The inhibition rates against Phytophthora cactorum of citronellol, neral, geraniol and geranial were: 100% at 28 × 10−3mg/mL air concentration; 38%, 41%, 50% and 51%, respectively, at 14 × 10−3mg/mL air concentration; 26%, 29%, 39%and40%0%, respectively, at 7 × 10−3 mg/mL air concentration; and 0%, 22 %, 35 % and 39 respectively, at 3.5 × 10−3mg/mL air concentration.
The $125,000 device relies on air concentration technology developed by the Sandia National Laboratories in Albuquerque, N.M.
The inhibition rates against Cryponectria parasitica of citronellol, neral, geraniol and geranial were: 36%, 62%, 44%and69%9%, respectively, at 28 × 10−3mg/mL air concentration; and 33%, 0%, 37% and 32%, respectively at 14 × 10−3mg/mL air concentration.
Decreasing the percentage of O2 from room air concentration (21%) to 14% did not change the amplitude of CSD.
