Comparison between lichen, conifer needles, resin-based passive air sampling devices (PASDs), and snow to monitor semi-volatile organic compounds (SOCs) in the atmosphere

Creator:

Schrlau, Jill E.

Abstract:

The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...

Improvements in synthesis and response techniques of ion-selective sensors

Creator:

Pylypiuk, Nataliia

Abstract:

Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...

Relative influence of trans-Pacific and regional atmospheric transport of polycyclic aromatic hydrocarbons (PAHs) in the Pacific Northwest (PNW), USA

Creator:

Lafontaine, Scott

Abstract:

The relative influences of trans-Pacific and regional atmospheric transport on measured concentrations of polycyclic aromatic hydrocarbons (PAHs), PAH derivatives [Nitro- (NPAH) and Oxy-(OPAH)], organic carbon (OC), and Particulate Matter (PM) less than 2.5 μm in diameter (PM₂.₅) were investigated in the Pacific Northwest, USA in 2010-2011. Ambient high volume PM₂.₅...
