ULTRASENSITIVE MICROTRACE PROCEDURE FOR MONITORING THE ORIGIN MOVEMENT AND FATE OF ANY LIQUID OR SOLID MATERIAL

摘要

A method of monitoring the movement of a material which comprises adding tothe material, as a microtrace additive,DNA molecules, sampling the resulting material after movement thereof anddetecting the presence of said microtrace additive inthe sample. The method is particularly suitable for use in monitoring themovement of oil shipments and the microtrace additiveis selected such that it will remain in the oil phase in the event the oil isdispersed in water e.g. sea water.
