Abstract

Passive air sampling allows spatially high resolved study designs and access to truly remote sites, but determination of the sampling efficiency, especially that of the particulate phase remains challenging. In this work, we present a self-directional passive air sampler which relies on the Venturi principle to enhance the sample air flow and to efficiently collect the air gas and particulate phases. Sample air flow rates ranged 1–13 m³ d⁻¹ depending on wind speed. The sampler was validated by side-by-side sampling with active air samplers at a central European continental site and a Caribbean coastal site.

The sampler is found suitable for monitoring organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) at trace concentrations in the remote environment (mostly 0.1–1 pg m⁻³ concentration range). For some OCPs these levels are among the lowest concentrations in air ever reported. The vertical distribution of polycyclic aromatic compounds, OCPs and PCBs at the rural continental site is found determined by advection in the planetary boundary layer during most seasons.

期刊介绍： Atmospheric Pollution Research (APR) is an international journal designed for the publication of articles on air pollution. Papers should present novel experimental results, theory and modeling of air pollution on local, regional, or global scales. Areas covered are research on inorganic, organic, and persistent organic air pollutants, air quality monitoring, air quality management, atmospheric dispersion and transport, air-surface (soil, water, and vegetation) exchange of pollutants, dry and wet deposition, indoor air quality, exposure assessment, health effects, satellite measurements, natural emissions, atmospheric chemistry, greenhouse gases, and effects on climate change.
