Main findings
In this monocentric, observational, longitudinal and retrospective
study, H2S exposure during pregnancy was associated with
accelerated onset of preeclampsia between the 20th and
37th week of amenorrhea in women living and/or working
in the Atlantic coastlines of Martinique. This finding is consistent
with previous studies in industrial and geothermic areas which have
reported associations between H2S exposure and
cardiovascular diseases, but conflict the great number of studies
suggesting cardioprotective action of H2S.
