What species suffered the most from ddt poisoning from the great lakes reigon?

Don't know the options, but I think a likely answer is fish-eating birds: they usually suffer the most from DDT poisoning: their reproduction is reduced and in extreme cases it even leads to death.

I'm going to go with 1,982 feet because of all of the ice.                                               ps its this is not the answer go with d 6,500.
