Developers amd stop-bath are relatively benign, even those for color
chemistry.  The fixer is the killer, though:  thiosulphates can pollute a
water supply with only a few parts per million.  Some of the more
sophisticated water systems are capable of catching these and taming them
but most cannot do so.  In a similar vein, it is the silver effluent
discharge which causes film-manufacturing plants to be regarded as
Unfriendly Neighbors.
