Levels of polycyclic aromatic hydrocarbons in Canadian mountain air and soil are controlled by proximity to roads.
Concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured in soil and XAD-based passive air samples taken from a total of 22 sites along three transects (Revelstoke, Yoho, andExpand

A review of measured bioaccumulation data on terrestrial plants for organic chemicals: Metrics, variability, and the need for standardized measurement protocols.
Quantifying the transfer of organic chemicals from the environment into terrestrial plants is essential for assessing human and ecological risks, using plants as environmental contaminationExpand

Comparison of headspace and gas-stripping techniques for measuring the air-water partititioning of normal alkanols (C4 to C10) : Effect of temperature, chain length, and adsorption to the water
The air−water partition coefficients of normal alkanols (C4 to C10) were determined as a function of temperature using both the phase ratio variation headspace (PRV−HS) method and the inertExpand

Spatial variability of atmospheric semivolatile organic compounds in Chile
Abstract In an effort to characterize the spatial variability of pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in the Chilean atmosphere, XAD-based passiveExpand

Current-use pesticide transport to Costa Rica's high-altitude tropical cloud forest.
To gain insight into the atmospheric transport and deposition of organic contaminants in high-altitude forests in the humid tropics, pesticides were analyzed in air, water, and soil samples fromExpand

Fate of pesticides in the arid subtropics, Botswana, Southern Africa.
Despite a history of pesticide usage, few data exist on their concentrations in air and soil of Southern Africa. To add to the understanding of the processes controlling the fate of organicExpand

Temporal trends of halogenated flame retardants in the atmosphere of the Canadian Great Lakes Basin (2005-2014).
Organic pollutants have been monitored in the atmosphere of the Great Lake Basin (GLB) since the 1990s in support of the Canada-US Great Lakes Water Quality Agreement and to determine theExpand

Investigation of bacterial hopanoid inputs to soils from Western Canada
Abstract Hopanoids have been widely used as characteristic biomarkers to study inputs of bacterial biomass to sediments because they are preserved in the geologic record. A limited number of studiesExpand
