I would be interested to know how the analysis was done
Here’s a quote from the first link below. You can try using google
or bing to check on the scientist, perhaps contact him:
“The jewelry testing was conducted by chemistry professor Jeff
Weidenhamer of Ashland University in Ohio, who over the past few
years has provided the government with results showing high lead
content in products that were later recalled.”
as the link is no longer current.
The link I provided on ABC News website is still current. Try
AP: Feds probe cadmium in kids’ jewelry from China By Justin
or this one:
US agency goes after cadmium in children’s jewelry By Justin
pritchard and jeff Donn Associated Press writers
or just do a search on “Associated Press” cadmium Chinese jewelry
There are plenty of hits. Various news outlets edited the AP story,
and some articles provide others left out.
