Inuit communities in Northern Quebec (Canada) are exposed to environmental contaminants, particularly to mercury, lead and polychlorinated biphenyls (PCBs). Previous studies reported adverse associations between these neurotoxicants and memory performance. Here we aimed to determine the associations of pre- and postnatal exposures to mercury, lead…

Advocates for civil rights, environmental justice, and movements promoting social justice require data and may lack trust in public authorities, turning instead to academic scientists to help address their questions. Assessing historical exposure to toxic chemicals, especially in situations of a specific industrial source of pollution affecting a…

Eliminating lead risks in PK-12 public and private schools was the focus of a facilitated workshop co-sponsored and organized by Healthy Schools Network, the Children's Environmental Health Network, and the Learning Disabilities Association of America. Held December 6-7, 2017, in Washington, DC, it included some 40 participants. They were experts…

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…

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…

States compel children to attend school; in fact, 98% of all school-age children attend schools--irrespective of conditions. Yet the environmental conditions of decayed facilities or facilities close to hazards can damage children's health and ability to learn. At the same time, it is well documented that healthy school facilities can help…

A large body of experimental animal research on the neurotoxic effects of certain environmental chemicals provides evidence of a cascade of neurobehavioural effects including learning deficits, hyperactivity, anxiety, depression, lack of motivation, increased aggressiveness, altered maternal care and bonding, and an over-reaction to small…

Children and adolescents, up to approximately age 20, are more susceptible than adults to potential health risks from chemicals and environmental hazards. Hazardous chemicals can interrupt or alter the normal development of a child's body, leading to lasting damage. Since children are smaller than adults, similar levels of exposure to toxic…

Doctors, nurses and other health care providers are making observational associations that individuals with existing disabilities or those who may be medically fragile are susceptible to adverse effects from toxic exposures than the general population. Because of this, the American Association on Mental Retardation has launched an Environmental…

Bridging the areas of political-economic sociology, the sociology of agriculture and environmental sociology, this study tests two hypotheses derived from a refined theory of foreign investment dependence. The hypotheses state that pesticide and fertilizer use intensity in less-developed countries are both positively associated with foreign…

Each of the elements required to create a healthy baby--genetics, the anatomy of the male and female reproductive system, the processes by which eggs and sperm are produced, the processes by which the embryo is created and implanted, maternal health during pregnancy, and embryonic/fetal growth and development--is vulnerable to damage by…

Designed as a "Participant's Manual" to be used as part of a "Chemical and Mercury Management in Schools Training," this document focuses on the policies and programs needed at the school and district level for safe and sustainable chemical and mercury management practices. This document is designed primarily for school…

This instructor's guide is a tool to help instructors promote the concepts of safe mercury and chemical management in schools. It contains three types of materials: (1) Guidance for the instructor/facilitator on conducting the training course (Section I); (2) A copy of all presentations with talking points as appropriate (Section II); and (3)…

Emerging research suggests that exposure to environmental pollutants, prenatally and in early childhood, may contribute significantly to diseases and disabilities. For example, exposures to mercury or lead early in life can impact the nervous system and brain, potentially contributing to learning, behavioral, and developmental disabilities. The…

The human response to an environmental hazard can either reduce or exacerbate its impact on health. This article reviews determinants of community-level responses to environmental health hazards. The aim is to identify factors that can enhance a community's capacity to protect itself and to suggest public health strategies that can increase such…
