AGI IRR was significantly elevated when the mean concentration, proportion NoV-GI positive samples, aNoV-GI positiveentration exceeded 1 genomic copy/L, 13%, and 14.7 genomic copiesamplesspectively.
In dwellings in the Netherlands, van Strien et al. (1994) found a mean Der p1 concentration of 2.4 μg/g for floor dust from living rooms, but in more than the half of the houses the maximum concentration exceeded 10 μg/g.
Maximum concentrations exceeding environmental quality standards or the Health-oriented Guideline Values were measured for 13 substances at individual sampling points.
The frequency of asthma ED visits was 33% higher (95% CI, 10-56%) when the daily 1-hr maximum ozone concentration exceeded 75 ppb (the 95th percentile).
Tsuruta et al. (2014) identified nine plumes, as listed in Fig. 3, that transported particulates to the land area of Japan and in which the maximum atmospheric 137Cs concentration exceeded 10 Bq m−3, based on a synoptic analysis using a time series of the SPM data and the wind vector field.
The maximum Fe concentration exceeds the USEPA guideline, and Al, Zn and Pb are close to or of the same order of magnitude as liminal values.
With this coupling mechanism, the concentrator's length-to-thickness ratio can exceed 7, the maximum concentration ratio exceeds 3.77, and angular tolerance at 90% of the maximum collection efficiency can reach ±35° and ±3° along the two incident axes and reach ±53° and ±9° at 50% of the maximum collection efficiency, respectively.
The maximum estimated 1-hr concentration exceeded 1500 nmole/m3 for H+ ions.
Annual maximum SS concentrations exceeded 2387.6 mg/L.
This is almost exclusively due to relatively high concentrations found for some individual PAHs: for BaP, BaA, CHR, BbFA and BeP (i.e., five out of eight PAHs restricted under REACH Annex XVII entry 50) the maximum pitch concentrations exceeded the concentration limits set for their presence in consumer articles (1 mg/kg) and toys (0.5 mg/kg).
During 1980 2000, 25.7% of the gridded, quarterly, average 1-hr maximum O3 concentrations exceeded the level of California's daily 1-hr standard (90 ppb), and 8.2% exceeded the federal daily 1-hr standard of 0.12 ppm.
