If you rushed out to buy a home lead-testing kit when all of Junior’s toys were recalled, hope you saved the receipt: a new study says that over-the-counter kits, usually used to test paint, aren’t reliable for playthings. The Consumer Product Safety Commission put 104 kits to the test and found that 56 failed to detect lead in toys, while two overachievers warned of the heavy metal where it didn’t exist. Concludes the CPSC, “Based on the study, consumers should not use lead test kits to evaluate consumer products for potential lead hazards.”
