New Applications for Passive Samplers : In-situ Flux and Risk Assessment of Legacy and Emerging Contaminants

Creator:

Tidwell, Lane G.

Abstract:

Passive sampling devices (PSDs) were used to measure air vapor and water dissolved phase concentrations of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) at two different environmentally contaminated sites. Environmental contaminates like PAHs and OPAHs are present in both the atmospheric and aqueous environmental compartments. It is known that...

Spatial and temporal variations of bioavailable polycyclic aromatic hydrocarbons in the lower Willamette River

Creator:

Sower, Gregory J.

Abstract:

Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and assessment of remediation efforts. To more effectively estimate human and ecological health risks, we evaluated the spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) in...
