Japan: Plastic-shopping-bag dye found laden with lead

A number of tinted plastic bags used in supermarkets contain high levels of lead, with some recording 250 times the EU safety standard, Kyoto researchers have found.

Dyes are believed to be the source of lead in bags. While most of Japan’s bags are burned at waste disposal plants, the researchers warned that residual ashes and bags that do not end up in the plants could pollute the environment.
