Whereas the United Nations Atmosphere Programme (UNEP) had beforehand identified around 13,000 plastic chemical compounds, the report by a team of European scientists discovered greater than 16,000 chemical compounds in plastics — 1 / 4 of that are considered hazardous to human well being and the setting.

Scientists flagged the necessity for higher transparency on what chemical compounds — together with components, processing aids, and impurities — are going into plastics – together with recycled merchandise.

1 / 4 of the recognized chemical compounds lack fundamental data on their fundamental chemical identification, the report mentioned.

“On the core of the issue is the chemical complexity of plastics,” mentioned Wagner, who additionally serves on the board of the Scientists’ Coalition for an Efficient Plastics Treaty.

“Usually producers don’t actually know which type of chemical compounds they’ve of their merchandise and that comes from very advanced worth chains.”

Solely 6% of the chemical compounds present in plastics are regulated internationally. With out regulatory stress, “there is no such thing as a motivation to reveal what’s within the plastics,” he mentioned.
