Gm. Solomon et al., STILLBIRTH AFTER OCCUPATIONAL EXPOSURE TO N-METHYL-2-PYRROLIDONE - A CASE-REPORT AND REVIEW OF THE LITERATURE, Journal of occupational and environmental medicine, 38(7), 1996, pp. 705-713
N-methyl-2-pyrrolidone is a solvent that is increasingly used in a var
iety of industries, including petroleum refining, microelectronics, pe
sticide formulation, and veterinary medicine. animal studies have demo
nstrated fetotoxic effects after maternal exposure to doses that have
minimal to no adverse effect on the mothers. The fetotoxicity comprise
s resorption, stillbirth, and low birthweight and delayed ossification
in surviving young. We report a human case of intrauterine growth ret
ardation followed by fetal demise at 31 weeks gestation. The mother wa
s a laboratory worker with no other apparent risk factors, who sustain
ed occupational exposure to N-methyl-2-pyrrolidone throughout the firs
t trimester of pregnancy. Laboratory work and solvent exposure have bo
th previously been associated with adverse reproductive outcomes. Labo
ratories and other industries that use suspected reproductive toxins s
hould have reproductive health policies in place that allow for decisi
on-making based on toxicologic review, exposure assessment, and medica
l evaluation. These policies should allow for voluntary removal of pro
spective parents until environmental assessment and controls are insti
tuted.
