Hello ladies and gentelmen,
I need some advices mostly about a/the/any articles and prepositions in my draft. And what is about general clarity of my sentences. So, I’ll give you a couple of sentences. It’s kind of long-term Chornobyl (Chernobyl) effects discussion. Thanks a lot in advance.
By the way, this question again, what is worse, to omit a proper article (a/the) or use it incorrectly (yes, I know better to use it correctly

)
So, my sentences:
A comparison of
the findings of animal research and human (public) health effects following the Chornobyl accident displays some similarities, but it requires utmost care. (It’s one of a top sentence and I did not discuss the findings yet)
We review
the well-documented human health effects detected
the years after the Chornobyl catastrophe.
Research/Studies
on test animals and wild animals (I mean lab rats and wild birds, yes, birds are animals too)
(The) Extremely important findings on long-term biological effects of Chornobyl radiation were received in studies
on wild inhabitants of the Chornobyl area. (wild inhabitants are birds)
Test animals
were fed by special forage contaminated of (the) Chornobyl fallout.
Thanks once more.
