A recent study conducted by Martin Wagner and Jörg Oehlmann has found a widespread contamination of mineral water with xenoestrogens that partly originates from compounds leaching from the plastic packaging material. The results indicate that a broader range of foodstuff may be contaminated with endocrine disruptors when packed in plastics. This provides first evidence that substances leaching from plastic food packaging materials act as functional estrogens in vivo. The researchers note it is probable that this estrogenic contamination originates from plastic food packaging materials because mineral water bottled in polyethylene terephthalate (PET) plastic bottles and Tetra Pak is more estrogenic than water bottled in glass.
