Comments
"Nitrogen mustards are vesicants causing skin, eye, and respiratory tract injury. Although these agents cause cellular changes within several minutes of contact, the onset of pain and other clinical effects is delayed for hours. Nitrogen mustards are alkylating agents that may cause bone marrow suppression and neurologic toxicity. . . . Nitrogen mustards may decrease fertility." [ATSDR MMG] Danger of skin sensitization; "Germ cell mutagens that have shown to increase the mutant frequency in the progeny of exposed mammals." [MAK]
