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...

Analysis of semi-volatile organic contaminants and their accumulation in remote aquatic ecosystems of the western US

Creator:

Ackerman, Luke K.

Abstract:

Many pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons are persistent, bio-accumulative, and toxic. These semi-volatile organic compounds (SOCs) can undergo atmospheric transport and deposition in cold, remote ecosystems. A better understanding of their accumulation in the fish of these ecosystems is important to better predict...
