The phrase "average concentrations for each" is correct and usable in written English.
It can be used when discussing measurements or data analysis, particularly in scientific or statistical contexts.
Example: "The study reported the average concentrations for each of the pollutants measured in the air samples."
Alternatives: "mean concentrations for each" or "typical concentrations for each".
Data gathered at the deposit/mine level in each countries are aggregated under the regions defined by the MRIO model and average concentrations for each metal are calculated in each regions for each type of mine.
Based on the LUR models, we generated a predicted spatial surface for annual average concentrations for each pollutant in a GIS with a resolution of 10 m.
Because it was not feasible to measure outdoor exposure for all 1,669 cohort addresses, we used GIS-based stochastic and dispersion exposure modeling to predict annual average concentrations for each cohort address.
The average concentration for each set of 10 plates was used to calculate the percentage of the full application rate that reached the stream channel.
The average concentration for each section was then assigned to all residents of that neighborhood.
We calculated the time-weighted average concentration for each time interval by multiplying the time between measurements in years by the average of the two measured concentrations.
The APS measured particle concentration in all size bins simultaneously every second and provided an average concentration for each 3-min interval.
The final concentration of the library mixture was determined by real-time quantitative PCR and the average concentration for each library was estimated.
Gestational diabetes was more common in urban versus nonurban subjects, but was increased among both urban and nonurban women with NOX above the average concentration for each population.
Briefly, concentrations were estimated by developing a national inventory of emissions for 1999, which was then used as input to an atmospheric dispersion model (Rosenbaum et al. 1999) that estimated average concentrations for 1999 for each census tract in the United States.
Daily concentrations of six criteria air pollutants were downloaded from the AQS [ 16] and temporally averaged to get annual mean concentrations for each monitor location from 2000 to 2005.
