Sentence examples for apportionment using from inspiring English sources

Until such studies are implemented, this paper provides a foundation to design future studies in sampling strategies for source apportionment using MM-PMF.

The efficacy of this modified LAM was demonstrated for total nitrogen (TN) source apportionment using a 6-year record of monthly water quality data for the ChangLe River in eastern China.

More work is needed to understand the origin of potential SOA and wintertime wood burning sources in Edmonton and the surrounding region and to apply source-risk apportionment using all available hazardous air pollutants (HAPs) including organic compounds to better interpret the potential health risk posed by various sources in urban areas.

A fourth strategy uses source apportionment analysis or "receptor modeling", a widely used technique that distinguishes emission sources, especially for PM, by apportionment using profiles and source impacts [ 27].

Sax et al. (2006) also did an indoor/outdoor source apportionment using a mass balance model, producing similar percentage contributions to personal risks from indoor and outdoor sources from all matched compounds between our studies.

In 1997, the GLRATI reported that (on- and nonroad) mobile sources contributed 27% of PAH emissions, while receptor-model derived apportionments (using Lake Michigan sediments) estimated 45%.

We conducted a source apportionment study using particle-phase organic molecular markers in personal and work area samples at a freight terminal in an urban area in 2003 (Sheesley et al. 2008a).

For example, Manton et al. (2003) suggest that the success of source apportionment studies using Pb isotopes in humans in the United States is about 1 in 5. We offered children whose PbB values were > 5 μg/dL follow-up with repeat sampling every 3 months until two successive decreases had been recorded.

To identify specific sources of current occupational particulate exposures, we conducted source apportionment studies using particle-phase organic molecular markers in work area samples from seven freight terminals sampled in 2002 and 2003 (Sheesley et al. 2008b) as well as in personal and work area samples in terminal workers and drivers at one terminal (Sheesley et al. 2008a).

Further the apportionment model used only considered the cholesterol effects of an egg, without considering other potentially beneficial components such as those described in this paper.

Source apportionment was used to estimate daily PM2.5 contributions from sources (traffic, road dust, oil combustion, and sea salt as well as a regional source representing coal combustion and other sources).
