free radicals/anti-oxidants

Does anyone have information on environmental and food free-radicals and
anti-oxidants in food suplements?

Also I am trying to track down some definitive info on soil degradation and
its relationship with food nutrition...

Any help in these areas would be greatly appreciated...

many thanks
