Název v původním jazyce

Study of the semipermeable membrane device kinetics for PAHs in the air

Popis výsledku v původním jazyce

Semipermeable membrane devices (SPMDs) are passive samplers consisting of a thin film of a synthetic lipid (triolein), sealed inside a layflat low-density polyethylene tubing. They are used most often for sampling of hydrophobic organic contaminants fromwater, occasionally also from air, sediments and soil. These devices are believed to integratively sample only readily bioavailable (dissolved and/or vapor phase) portion of hydrophobic contaminants, whilst the sampling process mimics the diffusional trransfer of organic contaminants through the membranes of aquatic organisms. Our study was focused on the mechanism of PAHs uptake from air by SPMDs. These devices were found to be able to sample not only vapour phase PAHs, but to certain extent also thePAHs present only in particulate phase. Main goal of our study was to observe the transport mechanisms of PAHs from the air into SPMDs. We tried to describe this process in detail using a mathematical modelling. We also made an attempt to
