These alterations persisted through 7 days, and the magnitudes of change increased with increasing DEP exposure doses
. At the higher DEP dose (100 mg/[m.sup.3]), the number of AMs and neutrophils in Listeria-infected rats were 2- and 4-7-fold that of the air and noninfected controls, respectively.

of EcoSan sludge.
This figure shows the average exposure dose
in a graphical form in which the individual zone doses are ordered, averaged, and plotted against the fraction of total area.
However the estimated potential dermal dose in Table III revealed that among the three patches, cotton gauze patches showed higher extrapolated dermal exposure dose
(0.0024 mg kg-1 day-1), which was around 5 times above the proposed acceptable operator exposure level (0.0005 mg kg-1 day-1).
(11) From these data and theoretical considerations, maximum permissible exposure doses
or limits are established and adopted by ANSI Z136.1.
Table 1 shows how proper technique can reduce exposure dose
. The decrease in mAs results in a 32% reduction in entrance dose for the 80 kVp exposure.
The committee concluded that a child's maximum daily oral exposure dose
was much lower that a proven no-observed-adverse-effect-level (NOAEL), offering a "wide margin of safety."
However, because 25 of the patients with R-type ACSSuTNx were part of an outbreak, they may have had an average higher exposure dose
, which may have contributed to some deaths (3).
On these occasions, a clinician must estimate the exposure dose
A HQ is calculated based on a model relating exposure dose
(ED) to accepted media toxicity reference values (TRVs) for selected species representing end-point receptor niches, typically earthworms, shrews, and robins.
Environmental Protection Agency set a safe exposure dose
for chromium at 350 times this amount.
In all BPA exposure studies, outcomes were measured between PND0 and PND540, and the exposure dose
ranged from 0.2 [micro]g/kg/d to 655 mg/kg/d.
An important problem was to determine the relationship between exposure dose
rates of Lake Druksiai biota resulting from natural and technogenic radionuclides.
"Even if a person walked through the site on every day (since March 11), the total exposure dose
should not be a cause for fear," he added.
