I've just played Civ2 for a while and I think the above is Civ2's behaviour.
I'm not sure about Mass Production or Plastic but the what I've seen is
this:
When Industrialisation is discovered pollution will be generated at a rate
of one per production shield for each shield over a certain threshold which
is governed by the cities size. The threshold value is calculated as:
20-(size*0.25). With the discovery of automobile the multiplier used in the
threshold equation becomes 0.50. Hydro plants effectively reduce the number
of shields used in the pollution calculation by 50%, I did n't play long
enough to see the effect of Mass Production, Recycling, etc.
