Probably.
As PV4 has alluded to, these artificial pitches are relatively new. There are limited studies because they are so new and the long term effects of these pitches won't be known for some time. Sure, the theory is similar to cigarettes. If this promotes more thought and science to become involved with ensuring that these pitches are scientifically safer, that can only be a good thing.
I remember playing at A pre season game at Hills Sports artificial pitch, the grass pitch was washed out, but the day we played was 30++. You could smell the pitch, and feel the heat radiating from the little rubber beads. It wouldn't surprise me if prolonged exposure, deep breathing also, could have side effects. Not to mention the acute physical injuries of knee and ankle injuries and superficial burns. We had a guy instinctively slide on it, burnt from below knee to halfway up his thigh, looked very nasty.
Anyway, i'd much prefer they look to make it safer now, than in 20 years time when they figure out 20years worth of players are developing issues.
