Fracaroli, Alejandro M.; Caminos, Daniel A. – Journal of Chemical Education, 2021
Scientists understand that no result is more important than the welfare of the investigators and the people around them. Safety culture is an integral part of industrial and academic jobs; however, safety training has only recently been added to chemistry classroom and laboratories. Chemistry laboratories expose workers to a variety of hazards,…

Davis, Eric J.; Pauls, Steve; Dick, Jonathan – Journal of Chemical Education, 2017
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…

Hayes, David; Widanski, Bozena – Journal of Chemical Education, 2013
A laboratory experiment is described that introduces students to "real-world" hazardous waste management issues chemists face. The students are required to define an analytical problem, choose a laboratory analysis method, investigate cost factors, consider quality-control issues, interpret the meaning of results, and provide management…
