Recent advances in vapor intrusion site investigations

The standard conceptual model for vapor intrusion consists of i) partitioning from groundwater or soil into soil gas, ii) diffusion through the vadose zone from the source area to the immediate vicinity of the building and iii) advection and/or diffusion through the building foundation (USEPA, 2015a, Fig. 1).Once vapors have entered a building, the indoor air containing these vapors is usually

VOC Chek 575 Series Passive Samplers for PPM-level

The Passive Sampler for Organic Vapors collects organic vapors without the use of a pump The sampler is validated for short-term and eight-hour sampling and 24-hour indoor sampling for some compounds Use the sampler to test exposure to VOCs such as toluene tetrachloroethylene trichloroethylene xylenes ethylbenzene 2-butanone (MEK) hexone (MIBK) benzene butyl acetates and styrene Models

How long does it take for VOCs to dissipate? | Indoor

Contrary to what many may believe, it is quite difficult to predict how long it takes volatile organic compounds (VOCs) to off-gas from new materials in a specific building.

Exhalation - Wikipedia

2019-1-19Exhalation (or expiration) is the flow of the breath out of an organism. In humans it is the movement of air from the lungs out of the airways, to the external environment during breathing.. This happens due to elastic properties of the lungs, as well as the internal intercostal muscles which lower the rib cage and decrease thoracic volume. As the thoracic diaphragm relaxes during exhalation

Atmospheric Deposition: Sampling Procedures,

2014-3-18Dry deposition occurs with several mechanisms like turbulent diffusion, sedimentation, Brownian diffusion, interception, inertial forces, electrical migration, thermophoresis, and diffusiophoresis [].Deposition rates are governed by meteorological factors (wind velocity, relative humidity), particle characteristics (size and shape), and surface characteristics (friction velocity, microscale
