Designing safer chemicals is an integral part of green chemistry that supports good health and well-being. The teaching of molecule design through relevant courses has important implications for the education of sustainable chemists. In these courses, training in toxicology and hazard assessment is essential for students to study benign chemical…

Background: The evidence base for the regulatory assessment of endocrine-disrupting chemicals (EDC) has proved very controversial to define. The EU has been a first mover and--after years of discussions and conflicts--adopted criteria for the pesticide and biocide sectors in 2018. Key points: The article reviews alternative regulatory options and…

Integration of computational data science (CDS) into the university curriculum offers several advantages for students, faculty and the institution. This article discusses the benefits to students of introducing CDS into the university curriculum with a focus on developing skills in cheminformatics, data analysis, structure--activity relationships,…

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…

Pesticide exposure represents a significant occupational health hazard for farmworkers, and handwashing is one strategy to reduce exposure via the dermal route. After learning about recent research findings regarding the lack of handwashing utilized by North Carolina farmworkers in the field, the North Carolina Farmworker Health Program approached…

Chemical flame-retardants are used in a variety of products to prevent the spread and occurrence of fire. While fire safety is critical, this family of chemicals, known as Polybrominated diphenyl ethers (PBDEs) are highly toxic. They are found in carpeting, foam cushions, polyester clothing and bedding, wallpaper, toys, household dust, a variety…

Introducing students to the process of scientific inquiry is a major goal of high school and college labs. Environmental toxins are of great concern and public interest. Modifications of a vertebrate developmental toxicity assay using the frog Xenopus laevis can support student-initiated toxicology experiments that are relevant to humans. Teams of…

Children's ability to identify common plants is a necessary prerequisite for learning botany. However, recent work has shown that children lack positive attitudes toward plants and are unable to identify them. We examined children's (aged 10-17) ability to discriminate between common toxic and non-toxic plants and their mature fruits presented in…

Exposure to toxic chemicals or environmental pollutants may harm the health of the nation's 74 million children and contribute to increases in asthma and developmental impairments. In 2007, 66 percent of children lived in counties exceeding allowable levels for at least one of the six principal air pollutants that cause or aggravate asthma,…

In the absence of scientific clarity regarding the potential health effects of occupational exposure to nanoparticles, there is a need for guidance in making decisions about hazards, risks, and controls (Schulte & Salmanca-Buentello, 2007). Presently, no guiding principles have been universally accepted for personal protective equipment that is…

Sanitizers and disinfectants can play an important role in protecting public health. They are designed to kill "pests," including infectious germs and other microorganisms such as bacteria, viruses, and fungi. Unfortunately, sanitizers and disinfectants also contain chemicals that are "pesticides." Exposure to persistent toxic…

Parents of children in the Saugus Union School District in California were concerned about the safety of classrooms, particularly portable classrooms. Their concerns were amplified by assertions of a local medical toxicologist following evaluations of some teachers and students, and by an Environmental Working Group report about alleged problems…

Background information is provided on the registered trademark "TLV" (Threshold Limit Value), the term used to express tolerable concentrations. The TLV of a compound is an estimate extrapolated from some defined damage to humans or animals at higher concentrations or by drawing analogies between similar concentrations. (JN)

Suggests that a literature survey can alert students to real-life ethical problems surrounding many organic compounds. Topic areas students could explore include: hazards in the workplace, toxic chemicals, and nerve gas structures. Background information and an extensive bibliography are given. (DH)

Draws conclusions on the scientific uncertainty surrounding most chemical use regulatory decisions, examining the evolution of law and science, benefit analysis, and improving information. Suggests: (1) rapid development of knowledge of chemical risks and (2) a regulatory system which is flexible to new scientific knowledge. (DH)
