Preeclampsia is a pregnancy-specific syndrome caused by abnormal placentation. Although environmental chemicals, including some pesticides, are suspected of impairing placentation and promoting preeclampsia, its relationship with preeclampsia has been insufficiently explored. We aimed to investigate the relation between non-occupational exposure pesticides during pregnancy risk preeclampsia. Th...

Characterizing human exposure to pesticides is challenging because their metabolites have a broad diversity of chemical structures. We aimed study the interest associating suspect screening and targeted analysis identify multiple pesticide pregnant women. Approximately 300 urinary samples collected during early pregnancy (France) were analyzed by UHPLC/HRMS using both approach multiresidue anal...

BACKGROUND, AIM, AND SCOPE In response to concerns about chemical substances that can alter the function of endocrine systems and may result in adverse effects on human and ecosystem health, a number of in vitro tests have been developed to identify and assess the endocrine disrupting potential of chemicals and environmental samples. One endpoint that is frequently used in in vitro models for t...
