Hi all-
I am not a chemistry major, or anyone who knows a lot about the goings on in a chem. lab. But I am a bird owner, and that is why I am here. There recently been discussions about lead in the powder coating of bird cages. Because birds are very sensitive to lead and there is a possibility of lead OD, owners are becoming concerned and sending out for testing.
I am wondering if you can clarify a few things for me? What is the best way to test for lead in the powdercoating of a cage? My friend is a chemical engineer and tested her powder coating of the cage using Inductively coupled plasma atomic absorption spectroscopy (ICP-AAS) after concentrated nitric acid digestion, in combination with energy-dispersive X-ray spectroscopy on the solid sample
and found a safe ppm of lead, which was to be expected because of the steel makeup of the cage.
Now, others are saying that "Your [her] results are not valid as you are testing a part of the cage and not just the paint and the part is taken into consideration as a factor in the parts per million.
Valid tests will test the paint and the paint only. Follow this link for information on the proper way to run the test, what to collect as a sample, what to ask for in the sample.

I fully trust my friend, but am hoping to get the input of others as to this matter, as all chaos has been breaking out in the bird world.
TYIA for any input and information. It is greatly appreciated!
