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.
