Marian Asantewah Nkansah

Marian Asantewah Nkansah  is a Ghanaian environmental chemist. Her research work focuses on finding solutions to environmental problems associated with levels and fate of toxic substances such as heavy/trace metals, persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in food, water, soil, rocks, sediments and other environmental samples. She also researches on the interaction of these pollutants with each other in the environment. In 2016, together with some scientists from the Kwame Nkrumah University of Science and Technology, she led a research which led to the confirmation that edible white clay poses potential cancer risk. In 2016, she became the first scientist to win the Fayzah M. Al-Kharafi Prize, an annual award that recognises exceptional women scientists from scientifically and technologically lagging countries. She and Collins Obuah, another scientist from the University of Ghana, were the two scientist selected to attend the Lindau Nobel Laureate meeting in 2017. In 2021, she was among five women recipients in developing countries of the OWSD-Elsevier Foundation Awards. She received the 2022 Africa Role Model Overall Female Personality Award, and was inducted as a Fellow of the Ghana Academy of Arts and Sciences the same year.
