Mackay, Donald published the artcileKinetic Delay in Partitioning and Parallel Particle Pathways: Under-appreciated Aspects of Environmental Transport, Category: alcohols-buliding-blocks, the main research area is hydrophobic chem kinetic delay organic medium equilibrium condition attainment; parallel particle pathway hydrophobic chem equilibrium condition attainment.
General conditions under which highly hydrophobic chems. or, more generally, chems. with high partition ratios (HPR) in water or air, may experience unexpectedly long kinetic delays in approaching equilibrium conditions with organic media are outlined. Such a hydrophobic delay for KOW, or an aerophobic delay for KOA, may be misinterpreted as being caused by a change in partitioning behavior or mechanism, resulting in development of non-linear regression models describing inter-media partitioning. The partitioning is fundamentally linear but is distorted by a kinetic delay in partitioning. To illustrate this concept, fundamental equations describing the diffusive equilibration processes, including a complementary transport mechanism termed a parallel particle pathway (PPP), were compiled. Such a mechanism may simultaneously occur, shortening the HPR delay and complicating interpretation. In addition, five examples where the HPR delay explains observed and occasionally difficult-to-interpret environmental behavior of chems., i.e., air-aerosol partitioning, chem. accumulation in indoor dust and surfaces, air/vegetation partitioning, internal transport in organisms, and fish bioaccumulation and toxicity studies, are described. The authors believe the general HPR delay and PPP issues deserve exposure as a commonly occurring, often under-appreciated process.
