Introduction: An earlier paper, "Chemical mark-
ers of possible hot spots on Mars" by A. S. Wong, S.
K. Atreya and Th. Encrenaz , explored the modifi-
cation of the atmosphere of Mars following an influx
of methane, sulfur dioxide and hydrogen sulfide (CH4,
SO2, H2S) from any outgassing sources which are re-
ferred to as hot spots. The feasibility of detection of
the new species by Planetary Fourier Spectrometer on
Mars Express is reported in a subsequent paper, "At-
mospheric photochemistry above possible martian hot
spots" by A. S. Wong, S. K. Atreya, V. Formisano, Th.
Encrenaz and N. Ignatiev . This abstract is a fol-
low-up on the previous two papers. Here we treat the
effect of any outgassed halogens rigorously. We also
make estimates of dilution factors relative to the source
location following convection and meridional trans-
