I was travelling a lot a couple of days ago across the countryside just outside of Krakow, and people are definitely burning plastics and trash, you can smell it even inside your car in the early hours of the morning.

It's coming from the surrounding areas, not the city itself.

Also one thing to note is that if pollution is bad in general then nearby fires and local sources of pollution will be much more noticeable. At least in my experience it seems to keep the pollution closer to the ground. Like if you are walking around a city with a lot of traffic on a day with bad pollution you will basically smell car exhaust all day whereas on days with low pollution even with the exact same amount of cars it will be much less noticeable.

A bit sad to hear, I expected Krakow suburbs to be better off.

Suburbs may be fine, but beyond them there's a ring of small towns and villages, and I bet most of the pollution is flowing from them down into the city.
