"Requirements for managing asbestos in buildings are much more rigorous than in the past and the asbestos levels found in the ambient air of schools during normal occupation are likely to be lower than in the past.
Perhaps it's a result, as some longtime observers of this generation have suggested, of growing up in an era of almost unremitting ambient anxiety: school years spent in the shadow of Columbine, 9/11 and, lately, widespread parental job losses.
Zhao et al. (1992) assessed biologic exposure of a small group of school children in Beijing, where ambient air has significant PAH pollution, and 1-OHP levels were elevated, as shown in Table 1.
In this study, the objective was to evaluate the effects of ambient air pollution on respiratory symptoms and diseases of school children, in addition to considering indoor air pollution.
Because of the seasonality of school attendance and both the seasonal and day-of-week variability of O3, the O3 population exposure for school absences was based on 2007 daily maps, rather than annual maps, obtained from interpolated hourly ambient school-week concentrations projected to 2000 census block group centroids.
The finding that urinary LG concentrations were slightly higher among those children that provided a sample in the afternoon rather than the morning suggests the potential influence of ambient or in-school exposures on urinary LG, but it is difficult to draw conclusions on this point with the limited number of observations.
The most successfully ambient of Eno's ambient albums is the 2012 release "Lux".
Subsequent analyses demonstrated that variation in ambient temperature explained 79% of the temporal variability of school-wide average indoor air concentrations of PCBs.
Travel distance is universally important for school cycling and is reliant amongst related home and school spatial proximity factors on a student's choice of schools.
We measured ambient levels of PM in the schools of study subjects, and individual exposure could be different from the ambient PM levels.
"The musical atmosphere is part of the ambient background of the entire show.
