Specialist forensic material suppliers have been making significant advances to help in the fight against cable theft, according to a report in Chemistry World. Markers based on DNA, used in other forensic applications, are not applicable in this area as they degrade in sunlight, so other, novel approaches based upon microscopic dots and ceramic nanoparticles have been developed.
These advances cover the ability to mark copper cables, lead from church roofs and other metals which have been subject to increasing levels of theft with the rise in metals commodities prices in recent years.
The new Scrap Metal Dealer’s Bill is currently undergoing its passage through Parliament, with the expectation that it will be published early in 2013. These scientific advances should be able to play a significant part in both preventing metal theft and bringing metal thieves to justice.
