@Doubtful,
Quote:I was wondering whether that short version was grammatically correct
Doubt, the more I think about it, the more I believe Rog to be absolutely right; though the diff is mighty subtle So let's try
Studies conducted in the Midwest found that many agricultural products contaminated (contaminate? both?) humans and the environment
The latter is probly better 'cause otherwise we might think the contamination had stopped, which it obviously hasn't
