Warning: Plastic materials such as polypropylene, used for preservation, may release harmful products: plasticizers, chlorinated or nitrated derivatives, or even acids. This is the case with polyvinyl chlorides (PVC) that can be found in storage pockets or boxes. However, the Photographic Activity Test (PAT) does not detect the presence of plasticizers and PVC. A box or a plastic bag may very well pass the Photographic Activity Test and contain PVC!
