"ERPG-2 is the maximum airborne concentration
below which nearly all individuals could be exposed for up to 1 hour without experiencing or developing irreversible or other serious health effects or symptoms which could impair an individual's ability to take protective action." 
In this study, we have implemented only 20% of inventory as the instantaneous airborne concentration
of isotopes with the puff release.
The comparison of airborne concentrations
of fungi and their derivatives, depending on the declared intensity of the occurrence of various signs of dampness and fungi growth and on the way the flat is used showed significant differences in the case of several reported signs of flat contamination.
Tracking by shoes or apparel or vacuuming can spread [Hg.sup.0], increasing airborne concentrations
and cleanup costs.
To achieve a comparable endotoxin dose through tidal breathing of ambient air over a 24-hr period would require an airborne concentration
of 900 EU/[m.sup.3], This is also well above the concentrations measured in the present study.
Studies have shown that significant percentages of the United States adults either don't know whether e-cigarette aerosols are harmful to children or believe they cause some or little harm, and the National Academies report also noted that there is 'conclusive evidence' that e-cigarette use increases airborne concentrations
of nicotine and particulate matter in indoor environments, compared with background levels.
Operations such as sawing, blowing, tear out and spraying may generate airborne concentrations
requiring additional respiratory protection.

of Fibrous Materials Detected With Phase Contrast Microscopy
The results of ergosterol level analysis, calculated concentrations of fungi and airborne concentrations
of fungi measured by means of the culturable method at workplaces, in total and in respective sampling points in the studied solid waste sorting plant, are presented in the Table 1.
Sherwin-Williams enhanced Harmony Interior Acrylic Latex Paint features innovations that help eliminate common odors and promote better indoor air quality by reducing airborne concentrations
of formaldehyde and other aldehydes.
The total airborne concentrations
of SVOC and VOC following the installation of vinyl flooring were simulated under two air change rates (0.5 [h.sup.-1] and1.5 [h.sup.-1]).
The law limits airborne concentrations
of PM2.5 fine dust particles emitted by diesel vehicles and other sources, and larger PM10 particles.
in the breathing zones of the operators were found to be <0.1 [micro]g/[m.sup.3] during the paint application to a vessel deck, in a tropical climate, in the open air.
In the office building studied, airborne concentrations
of nanoscale specks were higher than they were near a busy expressway.
