1. A method for detecting gaseous mercury using at least one sensing layer that absorbs molecules of gaseous mercury and at least one other gaseous chemical species, the method comprising:

  • heating the sensing layer;

    receiving measures of resistance from the sensing layer at different temperatures of the sensing layer; and

    detecting the gaseous mercury by distinguishing, by a processor, between the gaseous mercury and the at least one other gaseous chemical species using at least the measures of resistance and based on a rate of resistance change in the sensor layer relative to temperature of the sensing layer.
