Melbourne, April 29 : Drinking out of water bottles made from PET plastic may pose a human health risk, reveals a new study.

According to lead researcher Martin Wagner, Goethe University, Frankfurt, a questionable finger could be raised on the safety of the PET plastic water bottles.

The study found that estrogenic compounds trickle into the water in bottles made from PET (polyethylene terephthalate).
