Lab equipment is delicate and sensitive. Measurements must be precise and accurate. Pollution ruins that. Don't put your labs within pollution. This mod makes your labs take damage when inside an area of high pollution. That's all.

Why? Just to shake up your factory layout slightly, and why not.

Pollution Combinator likely goes well with this
Air Scrubber if you want a different solution than "keep your labs far away"
