Undergraduate students in an environmental chemistry laboratory course were taught QuEChERS (quick, easy, cheap, effective, rugged, and safe), a sample preparation procedure that is commonly used in pesticide laboratories involving an acetonitrile salt-out extraction of fresh produce samples followed by solid-phase dispersive cleanup using a…

This article reports on the implementation of a CURE project in an upper-level analytical chemistry course to engage a larger number of students in research at a primarily undergraduate institution (PUI). The lab course syllabus was modified to provide students with an opportunity to experience the process of conducting research through a project…

This experiment combines analytical techniques of solid-phase extraction (SPE) and gas chromatography quadrupole time-of-flight mass spectrometry (GC-QTOF-MS) to determine organochlorine pesticides (OCPs) in river water as a means to develop and improve student understanding of the use of GC-QTOF-MS for qualitative and quantitative analysis. In…

In the Fall of 2015 and in the 2016-2017 academic year, we conducted a two-week, team-taught, interdisciplinary module concurrently in an advanced biochemistry course, offered in the Chemistry and Biochemistry Department, and a sophomore-level environmental-ethics course, offered in the Religion Department, at Oberlin College. The focus of the…

An interdisciplinary course called "The Chemistry of Poisons" was created, featuring organic chemistry, biology, pharmacology, and toxicology content. This exploratory chemistry elective course was created by an instructor with a background in synthetic organic chemistry and a teaching assistant with a background in pharmacy practice.…

Chemical safety management is an iterative process where reviews of safety deficiencies (e.g., inspection notes) and failures (e.g., injuries) guide improvement efforts. The present work investigates safety in the school chemistry laboratory through two substudies. First, we interviewed 10 Swedish middle and high school chemistry teachers about…

Rapid growth in nanoscience and nanotechnology in recent years has been accompanied by studies of the toxicity and potential impacts of nanomaterials on human health and the environment, but less has been done concerning education in this area. There is therefore a need for courses that address this theme at universities worldwide, in order to…

Deborah Blum's New York Times bestselling nonfiction book "The Poisoner's Handbook" was used as supplementary reading in our first-term General/Organic/Biochemistry course. This course serves as both the first course for our Allied Health chemistry sequence and a core science course. Our goal was that, through reading this book, students…

A laboratory experiment was developed to target analytical chemistry students and to teach them about insecticides in food, sample extraction, and cleanup. Micro concentrations (sub-microgram/mL levels) of 12 insecticides spiked into apple juice samples are extracted using liquid-liquid extraction and cleaned up using either a primary-secondary…

As part of a university-wide project to explore Shakespeare's classic play, "Romeo and Juliet," from a variety of perspectives, an interdisciplinary talk was presented to the university community on the chemistry of the potions and poisons referenced in "Romeo and Juliet." To draw the multidisciplinary audience in and to teach…

The storyline of operas, with historical or fictional characters, often include potions and poisons. This has prompted a study of the chemistry behind some operatic plots. The results were originally presented as a lecture given at the University of Minho in Portugal, within the context of the International Year of Chemistry. The same lecture was…

The inexpensive and disposable electrode based on a double-polymer-modified pencil lead is proposed for upper-division undergraduate instrumental laboratories to enable the highly sensitive detection of perchlorate. Students fabricate and utilize their own electrodes in the 3-4 h laboratory session to learn important concepts and methods of…

Lead poisoning has been a problem since early history and continues into modern times. An appealing characteristic of lead is that many lead salts are sweet. In the absence of cane and beet sugars, early Romans used "sugar of lead" (lead acetate) to sweeten desserts, fruits, and sour wine. People most at risk would have been those who…

A molecule coming from outside an organism can form a ligand-receptor complex. Upon its formation, a message is transmitted, for example, to certain cells. In this way, two enantiomers can emit messages that differ, either quantitatively or qualitatively. In the present article, these facts are taken as a common basis for the actions of chiral…

The fish poisons derived from plants used throughout the world, not only as piscicides but also for a range of other uses, including insecticident and in folk medicines, is presented. The aim of this review is to provide a useful background for students interested in natural products.
