I am involved with a project with Mustard gas veterans but not porphyria .

Hello Karen

I really thought there would be studies, but I could not find any. However, I thought that I would add what I had found, although you have probably seen them. I will follow any further answers with interest.

See subject 3, p.170, but there is not a lot of detail:

Downey, D. C. (1999). Porphyria and chemicals. Medical Hypotheses, 53(2), 166-171.

http://www.ncbi.nlm.nih.gov/pubmed/10532713

This only lists porphyria (p.146):

Lacour, M., Zunder, T., Schmidtke, K., Vaith, P., & Scheidt, C. (2005). Multiple chemical sensitivity syndrome (MCS)–suggestions for an extension of the US MCS-case definition. International Journal of Hygiene and Environmental Health, 208(3), 141-151.

Levine, P. H., Richardson, P. K., Zolfaghari, L., Cleary, S. D., Geist, C. E., Potolicchio, S., ... & Kang, H. K. (2006). A study of Gulf War veterans with a possible deployment-related syndrome. Archives of environmental & occupational health, 61(6), 271-278.

http://www.ncbi.nlm.nih.gov/pubmed/17967750

This lists porphyria cutanea tarda once only:

Brown, M. (2005). Role of Science in Department of Veterans Affairs Disability Compensation Policies for Environmental and Occupational Illnesses and Injuries, The. JL & Pol'y, 13, 593.

These again only mentions porphyria:

Donnay, A., & Ziem, G. Porphyria, Porphyrinuria and Porphyrinopathy.

These are not academic papers but these websites were of interest:
