This spectrometer will also make possible high speed scanning of large area samples
that are of industrial relevance.
Therefore, neither the applicator or area samples
exceeded The American Conference of Governmental Industrial Hygienists' ("ACGIH") Threshold Limit Value-Time Weighted Average ("TLV-TWA") of 5 ppb.
In fact, after looking at other Northern Ontario communities that have similar metal statistics, Wren says the Sudbury area samples
actually featured a lower level of arsenic than places such as Wawa.

there is no significant difference between the two area sample
During the entire process, passive dosimetry for mercury vapor was employed to collect personal and area samples
Comparison of PbTx concentration obtained from area samples
taken with high-volume samplers showed that the personal samples indicated a lower exposure concentration (on the average about 50%) from those obtained from the area sample
The small geographic area samples
were selected from the States of Arizona, Georgia, Pennsylvania, Wisconsin, and Washington; States where the four PGPs were also located.
were collected near each process and were used by Kleissler as additional engineering data.
This approach uses data from air mass balancers, real-time air contaminant profiles, area samples
and tracer gas simulations of contaminant dispersion to form a composite picture of ventilation conditions.
These new market baskets--new geographic area samples
, new item structure, and new expenditure weights--will take effect with the index for January 1998.
Personal (breathing zone) air samples, as well as area samples
, were collected and analyzed using transmission electron microscopy.
At the base camp, area samples
collected by Placer have shown assays of 2.
