I'd be concerned about xylene. The typical xylene MSDS sheet probably 
contains verbiage like the following:

"Women may develop menstrual disorders, such as menorrhagia or 
metrorrhagia,infertility, and pathological pregnancy conditions 
including toxicosis, danger of miscarriage, and hemorrhaging during 
delivery. Repeated exposure of pregnant mice, rats and rabbits to the 
individual or the mixed isomers has resulted in maternal effects and 
effects on fertility, on the embryo or fetus, and specific developmental
abnormalities. Included among these effects are fetal death, 
fetotoxicity, pre-and post-implantation mortality, abortion, 
craniofacial and musculoskeletal abnormalities, and
extra embryonic structures."

Getting xylene out of the lab was one compelling reason for use of 
microwave protocols which replace xylene with 2-propanol.
