Don't you think it could result to health challenges in years to come?

I don't know, I don't think their is sufficient information available to make a conclusion. I do however know that because we lack information we should spend too much time worrying about the unknown.

I will add that so long as exposure is sufficiently small it shouldn't pose too much of an issue. However we should get a handle on environmental plastic contamination, to prevent our exposure from growing to the point where it could really be bad.
