Restricted substances in imported US packaging
Source: Greentech info
Nineteen US states have legislation that outlaws substances like cadmium, lead, mercury, and hexavalent chromium above certain concentration limits in packaging. But still a substantial amount of packaging contains restricted substances above the allowed levels.
In 2007, Toxics in Packaging Clearinghouse released the first comprehensive report on heavy metals in packaging, based on XRF screening.
Heavy metals like lead and cadmium were detected in imported packaging and components like flexible PVC, inks and colorants, and solder used in electronic circuits.
In 2008, the study was repeated. Still 14 per cent of all samples exceeded limit values for one or more of the restricted substances.
The results indicate progress in reducing the toxicity of the packaging waste stream and changing industry practices, but also indications of inferior testing and falsified certificates.
