The radioactive dust and water vapor in a mushroom cloud certainly isn't anything I'd want to inhale, but as far as disrupting the ozone layer,
nuclear testing isn't terribly significant. For one thing, there weren't that many atmospheric tests, and for another, atmospheric testing pretty
much ended in 1963, with the adoption of the Limited Test Ban Treaty. That's at least a decade before ozone depletion became a notable issue. It
seems very unlikely that nuclear blasts from 40 years ago are still impacting the ozone layer.
Also, the 'ozone holes' tend to form at the poles, where, as far as I know, nobody's ever done any nuclear testing.
