When I first learned about lead in children’s lunch boxes, I rushed to the hardware store to buy my own Home Lead Test Kit. I was concerned about my daughter’s commercial character backpack (which thankfully we no longer have), and we conducted our own Eco Child’s Play lead testing experiment. The results were negative, but now, I have learned that home lead test kits may not be accurate, thus neither was our experiment’s results reliable.
According to Grist, home lead test kits are not reliable for children’s toys: “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.” How are consumers supposed to feel safe? My daughter just received a bracelet from the prize box at school, and paranoid eco-mom wants to test it for lead. Is it worth the money to buy a home lead test kit? In light of the evidence that home lead tests are not reliable, the CPSC suggests worried parents send toys off to labs to be tested. Isn’t that the CPSC’s job? Consumer Reports followed the CPSC’s conclusions with their own tests. They report,
Our conclusion, that they can be limited but useful screening tools to identify lead in household products, is different from the Consumer Product Safety Commission’s recent announcement that consumers should not use these products to find lead in their homes. Our differences lie not as much in the testing itself as in the interpretation of the data. Here’s how we came to our conclusions and why we believe parents should consider these kits as a helpful tool for screening household products.

Speaking of lead, the NY Times last month asked, “Has the Clean Air Act done more to fight crime than any other policy in American history?” Since the Clean Air Act phased out lead in gasoline, crime rates have fallen. Not only does low levels of lead exposure in humans cause brain damage that affects intelligence, in some cases it causes people to act more impulsively and aggressively. This suggestion has of course come under scrutiny; however, the data is plausible. According to Jessica Wolpaw Reyes, an economist at Amherst College, the rise and fall of lead-exposure rates seem to match the rates of violent crime, if you account for a 20-year lag. Two decades is ” just long enough for children exposed to the highest levels of lead in 1973 to reach their most violence-prone years in the early ’90s, when crime rates hit their peak.”
Hopefully, I can stop ranting about lead for awhile and move onto other issues.
