L'analyse, après dissection, d'un gros échantillon de PC hors d'usage a permis d'évaluer la contribution de ces engins à la charge polluante en métaux lourds nuisibles : parmi les ordures ménagères, ils contribuent relativement peu à l'apport en cadmium et en mercure mais beaucoup à celle en cuivre, étain et nickel.
