Webosmosis: the transport of water through a semipermeable membrane from an area of high water concentration to an area of low water concentration across a membrane. … Web1 day ago · We calculate individual cancer risk by multiplying the estimated lifetime exposure to the ambient concentration of each HAP (in μg/m 3) by its URE. The URE is an upper-bound estimate of an individual's incremental risk of contracting cancer over a lifetime of exposure to a concentration of 1 microgram of the pollutant per cubic meter of air.
