Abstract
The potential for mapping certain types of industrial pollution by the measurement of vanadium in jack pine needles has been investigated. A rapid instrumental neutron activation method for the analysis of V, Al, Ca, Na, Mn and Cl at parts per million concentrations in jack pine needles has been developed with the SLOWPOKE nuclear reactor. Detection and determination limits (Currie, 1968) for vanadium in 100 mg of ground needle tissue were 0.36 ppm and 1.6 ppm, respectively.
