Somasundarapalya smell now in HSR sector 1

If you’ve ever been towards the Somasundarapalya side (I think it starts after 27th Main), there’s this unbearable smell in the air. I’m not sure what the source is.

Now the same smell has started reaching Sector 1 on the other end of 27th Main as well. 😟🤢

Does anyone know what’s causing it? This is getting pretty bad.
