The Pas-DD device comprises a top cover plate, a bottom plate connected to and spaced a distance apart from the top cover plate, and at least one sampling media supported by the bottom plate and positioned within the device in an orientation accessible for collecting particles in the environment. The top cover plate and bottom plate may be oriented in parallel, and spaced apart a distanced that can be optimized for air sampling a broad size-range of depositing particles. The passive air sampling device and method disclosed are particularly useful for sampling air in regions where access to electricity is difficult, and for estimating atmospheric loadings of polycyclic aromatic hydrocarbons and other semi-volatile compounds."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Passive dry deposition (PAS-DD) collector","description":"A passive dry deposit (Pas-DD) air sampling device and method for sampling volatile, semi-volatile, or particulate matter in air.
