Primary research interest includes better understanding of the sources and toxic effects of Emerging Contaminants (ECs) and their metabolites in surface and groundwater. There is an increasing number of pharmaceutical and personal care products (PPCPs) being detected in the environment, particularly in freshwaters that also serve as vital sources of drinking water (Kolpin et al.). Because many of these ECs are designed to be biologically active, there is concern that even low dose exposure may result in endocrine disruption effects that may pose risk to ecological and human health (Daughton and Ternes).
In addition to teaching at DePaul, Maya Zein PhD, has experience conducting human health and ecological risk assessments as a consultant at ERM. Other experiences include:
-Supporting chemical product risk and regulatory compliance projects, including REACH, GHS, US Federal and State product regulations, as well as emerging market product regulations.
-Assisting clients in developing product stewardship strategies, incorporating industry product stewardship practices and engaging with appropriate legal resources, where appropriate.
-Screening and evaluating substance study reports (i.e., environmental fate and effect studies, mammalian toxicology studies) and preparation of robust study summaries.
