Assessing soil-air partitioning of PAHs and PCBs with a new fugacity passive sampler

Abstract: Soil-air fluxes of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) were determined using a novel application of passive samplers to measure air and soil air, which is air in close proximity and in equilibrium with soil. Existing methods to measure flux of semi-volatile compounds between soil and air require collecting samples from the top soil layer. Yet, the top soil layer is hard to define and oversampling may misrepresent the exchangeable fraction. Alternatively, modified active… Show more

“…Passive sampling devices were used to measure two matrices: air at an approximate height of 1.5 m and turf air, air immediately above and in close contact with turf (analogous to soil pore air). Paired air and turf air boxes, as described in Donald and Anderson (2017) were deployed at the three locations with triplicate equipment at outdoor A. Additional site details including weather conditions, photographs, and figures are provided in SI.…”

“…The strips were pre-conditioned in solvent baths, dried, and a solution containing performance reference compounds (PRCs) infused into each before heatsealing. Infusion with PRCs allows calculation of in situ air sampling rates and time-integrated air concentrations, as used in Donald and Anderson (2017) and preceding works. Inclusion of PRCs means that the environmental concentrations can be calculated before the samplers reach equilibrium with the environmental matrix.…”
