A new unit for pollution ?



Dont blame me too much if I go away from computational chemistry topic this
 time, but this BBS is the only one of which allows me to speak with others
 chemists.
 --- be indulgent I'am just testing an idea ---
 Dear Netters,
 A few days ago, I proposed the following message to the biosph-L BBS.
 As now a small program is available for this calculation, I submit this idea
 for your cristicism. I hope that this subject which deals with modelling of
 pollution will be of interest to some of you. I will summarize in two weeks.

 Subject: a new unit for pollution ?
 Aside discussion about the conference of Rio
 ============================================
 The conference of Rio gives me the opportunity to propose a
 potentially new method to account for the relative level of
 pollution.
 I suggest the creation of a pollution unit which would
 quantize this level, so that people could gain a better
 understanding of the effects of their pollution on the
 bio-sphere.
 This unit situated at the molecular level could be calculated
 as the number of molecules contained in one litre of air or
 water (or "bio-fluids") after complete dispersion of the polluant
 into the atmosphere or water supply.
 	      m      <---- nbre of molecules of polluant
      Pol = --------
 	      M      <---- nbre of litres of the bio-fluid present
 			   on the earth
 Because of the magnitude of Avogadro's number this unit will be
 sufficiently sensible to the human mind.
 In it's conception it is of the same order of magnitude as the
 Becquerel radiation unit.
 examples :
 ========
 A few month ago I made a the calculation for the exhaust of a
 car burning 8 liters/100km :
 (it should be checked)
 it gives                          -1    -1
         683 molecules. liter of air   km   = 683 Pol/km for CO2
 				  -1    -1
         0.2 molecules. liter of air   km   = 0.2 Pol/km for HC
 It means that when you drive 1 km, everybody on the earth will
 get 683 CO2 molecules more for one liter of air.
 Values for the total mass of bio-fluids
 =======================================
 The reference values for the mass of atmosphere was taken from
 The Handbook of Chemistry and Physics (69th edition) according
 to A.Poldervart 1955.
 This point could change slightly in the future (but less than
 one order of magnitude).
 I will be  happy to hear about such a unit if it already exists,
 and I will summarize  all comments and answers.
 Also any suggestion on the best way to submit it to a
 scientific standard organisation would be appreciated.
