Environmental forensics is the application of knowledge from geosciences and chemistry in a legal setting, e.g., to determine the origin and consequences of contamination events. Teaching environmental forensics requires reactivating prior knowledge from different fields of natural sciences, filling knowledge gaps, and connecting pieces of…

Children spend as much as ten hours per day, five days a week in childcare centers and preschools. In providing healthy environments, these facilities deal with a variety of pest and pesticide issues influenced by their geographic location, local environment, and pesticide regulations. Some rely extensively on pesticides while others use…

This paper describes a method for determination of trihalomethanes (THMs) in drinking water via solid-phase microextraction (SPME) GC/MS as a means to develop and improve student understanding of the use of GC/MS for qualitative and quantitative analysis. In the classroom, students are introduced to SPME, GC/MS instrumentation, and the use of MS…

Presented is a project-based learning (PBL) laboratory approach for an upper-division environmental chemistry or quantitative analysis course. In this work, a combined laboratory class of 11 environmental chemistry students developed a method based on published EPA methods for the extraction of dichlorodiphenyltrichloroethane (DDT) and its…

Maternal immune activity has been linked to children with autism spectrum disorder (ASD). We examined maternal occupational exposure to asthma-causing agents during pregnancy in relation to ASD risk. Our sample included 463 ASD cases and 710 general population controls from the Study to Explore Early Development whose mothers reported at least one…
