Tests are available to measure blood levels of different toxic metals found at workplace.In fact methods to measure the levels of these toxic metals and compounds have been described.
I am giving below a couple of links which give much detail about these toxic metals and how to measure them.
I am changing this to question and answer mode as you seem to be offline.
You may ask any questions you may have on the issue
Is there a test for the lungs
No.The levels are measured in blood stream or at the workplace atmosphere
we had a specialist come in and check the air, we never got the results but management said everything was ok. 6 people including myself got cancer in the last 2 years. do you know if I can anonymously get a doctor/specialist to come in and inspect the workplace
That is a question best answered by a lawyer as I do not know if it is legal to do so and even if this is done how much would be the credibility of results obtained this way.
ok thanks for your help Doc, have a good day.
