Wow. The problem is, this immediately makes me consider all the industrial pollution sites across the world. I genuinely wonder how much of our planet has already been rendered completely inhospitable to life? I'm not trying to be dramatic or bait arguments, I legitimately wonder how much.
The shelling, in Verdun for example, was so absurd that it's not really relatable to pollution. It was days upon days of non stop shells, including chemical shells, going over the same ground back and forth, for weeks if not months.
It really was something completely off the charts.
Edit0: from the wiki on the battle of verdun:
It lasted from february to december - in the very first 10h bombardment, on the first day, over 1 000 000 shells were shot over a 30km x 5 km strip.
It's pretty difficult to make an area inhospitable to all life, including microbial (though I guess massive arsenic poisoning will do it). But as soon as you start thinking like that, then you wind up with a very boring sliding scale of hospitality for microbes, fungus, weeds, insects...

As has already been pointed out by multiple people, none of it. That's not a thing it's possible to do.
If you really were legitimately wondering about this... you need to find some sources of information that aren't just lies.
