Dr. Pollitt’s research explores the human exposome through characterisation of environmental and biological samples using analytical and mass spectrometry (MS) techniques. Her group has developed various mass spectrometry (ICP-MS, LC-MS and GC-MS) to measure exposure to complex mixtures of trace elements and organic compounds. She has applied these exposure assessment methods in numerous in epidemiological studies.

  • Environmental factors in placental pathology
    Toronto, ON, Canada 2019
    The placenta is an organ that develops during pregnancy. It transfers oxygen and nutrients from the mother to the fetus and allows for the removal of waste products from the fetus. Placental changes during pregnancy are normal and important to a healthy pregnancy. Abnormal changes can occur when the mother is exposed to certain risk factors and toxins, resulting in placental dysfunction. Placental dysfunction often involves changes to the blood vessels of the placenta, leading to reduced oxygen
