Sampling bias caused by materials used to monitor halocarbons in groundwater
TL;DR: In this paper, the authors evaluated materials used in the construction of groundwater monitors for their potential to cause sampling bias, and found that poly(tetrafluoroethylene) and rigid poly(vinyl chloride) absorbed the compounds.

The effects of snow and ice on the environmental behaviour of hydrophobic organic chemicals
TL;DR: A review of the roles of snow and ice as they influence the environmental fate of hydrophobic organic chemicals (HOCs) is presented in this paper, where it is concluded that snow is an efficient scavenger of HOCs from the atmosphere both by adsorption of gaseous HOs to the ice interface and by particle scavenging.

Partitioning of organic chemicals at the air-water interface in environmental systems
TL;DR: In this paper, it is suggested that partitioning organic chemicals to the air-water interface can be significant and must be quantified in several situations of environmental interest including partitioning of chemicals into small air bubbles in water into small water drops in air (for example, fogs), and between the phases present in relatively dry soils.

Sorption of organic vapors at the air-water interface in a sandy aquifer material
TL;DR: In this paper, it was hypothesized that the mineral surfaces in a sandy aquifer material would be sufficiently hydrated in a GC column fed with humidified carrier gas to provide an airwater interface for the sorption of nonpolar organic vapors.

Modelling the fate of non-polar organic chemicals during the melting of an Arctic snowpack
TL;DR: In this article, a simple fugacity-based chemical fate model is used to describe quantitatively the behaviour of selected non-polar organic contaminants during snowpack melting, namely atmosphere-snow exchange, redistribution within the snowpack and draining with meltwater.
