I'd like to add another difference: nuclear pollutants have very long
half-lifes (up to many thousands of years for their radioactivity to
be reduced by half).
Genetic pollutants in the form of mutant bacteria, plants or animals
reproduce and multiply, so they don't have half-lives but doubling
times. (A bacteria's is around 20 minutes under favorable conditions).
Once a runaway genetically-engineered mutant is released into the
environment, recalling it will be next to impossible.
