It could be lots of things. You're not helping to narrow those alternatives. So, consider taking a sample to: * An analytical laboratory. * Teachers in the chemistry department at a local university.

Kester recommends the following independent labs: * Foresite, Inc. (765) 457-8095 http://www.residues.com * American Competitiveness Institute (610) 362-1200 http://www.aciusa.org * Trace Labs http://www.tracelabs.com * Schenectady Materials and Processes Laboratory (518) 382-0082 http://www.the-mandp-lab.com * Bodycote Taussig (847) 676-2100 * Robisan Laboratory, Inc (317) 353-6249 http://www.robisan.com * Precision Analytical Laboratory (765) 455-1993 http://www.precisionanalysts.com

Here's an article our lab has published about green contamination - http://www.residues.com/pdfs/foresite_green.pdf If you are concerned with finding out just what is there and what the cause is, I would agree with davef that it would be helpful for you to consult with an independant laboratory.
