Laboratory Round Robin Test Project: Assessing Performance in Measuring Toxics in Packaging
This report summarizes the performance of laboratories in determining compliance with the 100 ppm limit of toxics in packaging requirements. Based on the findings, the report presents recommendations for regulated entities (such as packaging suppliers, manufacturers and distributors of packaged products) and test laboratories to ensure that testing measured total concentration of restricted metals in the sample.

WA & IA Reusable Bag Testing
TPCH member states Washington and Iowa tested 31 reusable bags and found most complied with state toxics in packaging laws.
Assessment of Heavy Metals in Packaging: 2009 Update
This report documents the continued investigation by TPCH of heavy metals in packaging, using XRF analysis. TPCH screened 409 packages to detect trends in compliance with state toxics in packaging laws, and to notify brand owners of potentially non-compliant packages. This project was funded in part by the U.S. EPA New England.
Assessment of Heavy Metals in Packaging
The Toxics in Packaging Clearinghouse screened 355 packages for the presence of four restricted metals (lead, cadmium, mercury, and hexavalent chromium) between October 2005 and February 2006 using a portable x-ray fluorescence analyzer. The results of this EPA-funded project were released in June 2007.
Model Legislation Evaluation Reports
The Toxics in Packaging Clearinghouse and member states periodically review the effectiveness of the Model Toxics in Packaging Legislation and state laws based on the Model. The first such review, Model Toxics in Packaging Legislation: An Evaluation of its Provisions, Administration, and Impact, was published in 1994, and the second review was published in 1998.
