Arsenu (As) iz podzemnih voda izloženi su milijuni ljudi koji žive u dvanaest administrativnih jedinica Zapadnoga Bengala u Indiji. Njegovo štetno djelovanje na ishod trudnoće (mrtvorođenja i spontane pobačaje) tek treba kvalitetno dokumentirati. Istražen je utjecaj izloženosti arsenu na ishod trudnoće u bengalskih žena koje su mu bile izložene putem pitke vode, a stanovnice su različitih sela u administrativnoj jedinici North 24 Parganas savezne države Zapadni Bengal. Rezultati istraživanja pokazali su značajno veću učestalost mrtvorođenja i spontanih pobačaja u žena izloženih arsenu u odnosu na neizloženu skupinu. Twelve districts of the state of West Bengal, India are affected by arsenic (As) and millions of individuals are consuming As-contaminated groundwater. The probable adverse effects of As on pregnancy outcome (stillbirth and miscarriage) are yet to be properly studied. The present investigation is an attempt to understand the effects of As exposure on the pregnancy outcome in Bengali women exposed to As through drinking water and residing in different villages in North 24 Parganas District of West Bengal. The results show a significantly higher rate of stillbirths and miscarriages than those in the unexposed population.
