Abstract

Maternal characteristics and physiological changes during gestation such as gestational weight gain (GWG) may have an influence on the overall burden of organohalogen compounds in neonates. We have observed that neonatal concentrations of these compounds were inversely associated with GWG after adjustment for age, pre-pregnancy body mass index, educational level, and fish consumption. On average, neonates of women with GWG as recommended by the Institute of Medicine (IOM) or better had lower concentrations of these pollutants than neonates of mothers with unsuitably low GWG. Furthermore, we have observed that insufficient GWG also increases pollutant transfer to infants during breastfeeding, which considerably extends the significance of this physiological change as regards the pollutant intake of children in the early years of their life.

Author Biography

Joan O. Grimalt, Institut de Diagnosi Ambiental i Estudis de l’Aigua (IDAEA-CSIC)

Joan O. Grimalt, nat a Palma (Mallorca, 1956), és enginyer químic per l’Institut Químic de Sarrià (1978), llicenciat en ciències químiques per la Universitat Autònoma de Barcelona (UAB, 1979) i doctor en ciències químiques per la UAB (1983). És professor d’investigació del Consell Superior d’Investigacions Científiques (CSIC) des del 1992 i membre numerari de l’Institut d’Estudis Catalans des del 2013. Com a geoquímic orgànic ambiental s’ha dedicat a l’estudi dels compostos orgànics naturals i antropogènics com a indicadors del canvi climàtic i de l’estat de salut dels ecosistemes i organismes (inclosos els humans). Ha estat director de l’Institut de Diagnosi Ambiental i Estudis de l’Aigua (IDAEA-CSIC, 2008-2018) i del Centre d’Investigació i Desenvolupament (CID-CSIC, 2012-2018). Ha publicat més de set-cents articles científics citats més de vint-i-vuit mil vegades. Ha dirigit cinquanta-tres tesis doctorals i va rebre el Premi Rei Jaume I de la Preservació del Medi Ambient (Generalitat Valenciana) l’any 2005 i el de l’Excel·lència Científica de la Societat Catalana de Química el 2022.
