Planning objection help

Mee

Apologies if this is the wrong place.
I would welcome experience of others.
 In short the office block nearby wants to adapt the building to make it lab-space ready. The adaptations - erection of a substation,  numerous DX Units, roof and ground floor ventiliation and emission infrastructure suggest (there is a lack of detail on this) it will be wet-labs with their associative chemical and waste hazards. The area is also in a flood zone (3).

In essence it is a change of use from offices to industry, but does not explicitly apply for a change of use.

The noise impacts assessment show a failure to adhere to British Standards and government advice - no use of windshield and only one monitoring point  (on the building itself) etc and one photo shows the removal of a key heritage landmark  from the image, and elevations (possibly not applied for) which are slowly obscuring said view. I have taken my own photo of the same view that illustrates this.

Can I object on some of those 'technical' issues. And how do I politely state they have photoshopped a key image apart from presenting actual image and pointing out a certain building and features are missing from one of the images in supporting documentation.

The council is keen to expand lab space, but we already have similar developments nearby and I think many see laboratories as benign or or somehow clean, but they can be  industrial in function and operation.

It seems from the timing of the letter and wording in the application and documents that both parties seem to think this is a forgone conclusion and may be it is, but I think I have to try to highlight concerns about the proximity to residents of new hazards and the inadquate impact assessments.

Thanks

What's a DX unit?  Why does it need a wind shield?  How nearby is nearby?
