ABSTRACT
One part in 1,000,000,000,000,000 parts! Believe it or not, analytic measurements down to this detection level (parts per quadrillion, ppq) are quickly becoming routine for certain classes of organic compounds (for example, the polychlorinated dibenzo-dioxins and -furans). With the lightning-fast progress being made by chemists, physicists, and other scientists, we can only expect this trend to continue. Consequently, everyone involved with water in the food and beverage industries, either as an ingredient, product, or process chemical, will be forced to learn more
about this often complex matrix-from its origin, through the paths it travels, the contaminants it meets along the way, to the point where it enters your production facility.
