The phrase "air concentrations values" is not correct in written English.
The correct form would be "air concentration values" or "air concentrations."
Example: "The study measured the air concentration values of various pollutants in the urban area."
Alternatives: "air quality values" or "atmospheric concentration values."
Personal exposure values for H2O2and NH3 (averages [standard deviations] are 0.05 [0.04] and 0.90 [0.76] mg.m-3, respectively) were greater than workplace ambient air concentrations (corresponding values of 0.04 [0.03] and 0.68 [0.42] mg.m-3) for H2O2 and NH3, with no significant seasonal variation.
We used plant-specific air concentrations to assign values to the qualitative (high, medium, low, background) inhalation and dermal exposure ratings, with dermal exposure values unitless.
Therefore, we calculated Kendall's τ rank correlation coefficients, adjusted for censored data, to explore linear relationships between dust and air concentrations, with p-values obtained from 10 000 bootstrap replications.
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.
As in prior analysis (Perera et al. 2003), a composite PAH variable was computed from the eight inter-correlated PAH air concentration measures (r values ranging from 0.34 to 0.94; all p-values < 0.001 by Spearman's rank).
Measurements of air concentrations in vanadium factories yielded values in the range of 0.02 5 mg/m (IARC 2006).
Using values of Akaike's information criterion obtained under the two models, we found strong statistical evidence favoring two metabolic pathways, with respective affinities (benzene air concentrations analogous to K m values) of 301 ppm for the low-affinity pathway (probably dominated by cytochrome P450 enzyme 2E1) and 0.594 ppm for the high-affinity pathway (unknown).
Uptake of native PCBs behavior was extremely variable, probably due to changes in ambient air concentrations and resulted in R-values of 1.6 11.5 m3 d−1 with greater variation seen in higher chlorinated homolog groups.
The posterior values for tap water and ambient air concentrations provide a better match to the observed values than do the priors, particularly for the median blood concentration.
SI Figure S7 shows dust and gas-phase air concentrations categorized by rounded log Koa values.
