The reproductive, developmental, and postnatal toxicity of 14 select c
hemicals and mixtures that are components of gasoline has been reviewe
d. The majority of experimental analyses have been performed as either
variations of the accepted segment 2 protocol or as traditional terat
ology studies. Specific deficiencies in the present database have been
identified and are most obvious in the evaluation of reproductive and
postnatal effects. It is recommended that future studies address the
continuing need for assessment in multiple species and over a range of
dosages with specific emphasis on the impact of route of administrati
on on the results obtained.
