Laboratory rodent diets contain toxic levels of environmental contaminants: Implications for regulatory tests

The quality of diets in rodent feeding trials is crucial. We describe the contamination with environmental pollutants of 13 laboratory rodent diets from 5 continents. Measurements were performed using accredited methodologies. All diets were contaminated with pesticides (1-6 out of 262 measured), heavy metals (2-3 out of 4, mostly lead …

The conceptual imperfection of aquatic risk assessment tests: highlighting the need for tests designed to detect therapeutic effects of pharmaceutical contaminants

Standardized ecotoxicological tests still constitute the fundamental tools when doing risk-assessment of aquatic contaminants. These protocols are managed towards minimal mortality in the controls, which is not representative for natural systems where mortality is often high. This methodological bias, generated from assays where mortality in the control group is systematically …

Nanomaterials vs ambient ultrafine particles: an opportunity to exchange toxicology knowledge

A rich literature exists that has demonstrated adverse human health effects following exposure to ambient air particulate matter (PM), with strong support for an important role for ultrafine (nano-sized) particles. At present, relatively little human health or epidemiology data exists for engineered nanomaterials (NM) despite clear parallels in their physicochemical …

Rising CO2, climate change, and public health: Exploring the links to plant biology

Although the issue of anthropogenic climate forcing and public health is widely recognized, one fundamental aspect has remained underappreciated: the impact of climatic change on plant biology and the well-being of human systems. The authors aimed to critically evaluate the extant and probable links between plant function and human health, …

Embryonic stem cells' could help to study pollution effects on human health

Researchers claim that embryonic stem cells can help in studying the effects of pollution on human health. In the study, the researchers from the University of California have successfully detailed the use of stem cells to gauge the neurotoxicity effects of the environmental pollutant Bisphenol A (BPA). The researchers used …

Neurobehavioural effects of developmental toxicity

Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review …

The toxic effects of cigarette additives. Philip Morris' project mix reconsidered: An analysis of documents released through litigation

In 2009, the promulgation of US Food and Drug Administration (FDA) tobacco regulation focused attention on cigarette flavor additives. The tobacco industry had prepared for this eventuality by initiating a research program focusing on additive toxicity. The objective of this study was to analyze Philip Morris' Project MIX as a …

Healthy food not so healthy

Most food items contain toxins like mercury, pesticides and acrylamide that can affect children in the long run Even healthy food like fruit, vegetables, meat and fish might be putting children’s health at risk. These food items also contain toxins like mercury, pesticides and acrylamide that can, over a long …

Chemical "soup" clouds connection between toxins and poor health

From plastics to flame retardants, the ubiquitous chemicals of our daily lives have raised public health concerns like never before. Inside the Beltway, however, data-crunching scientists are often no match for industry lobbyists and corporate lawyers. The exception, no doubt, is Linda Birnbaum, the toxicologist who leads, two little-known scientific …

Drug-pollution law all washed up

Europe is set to quash a precedent-setting initiative designed to tackle a disturbing side effect of common drugs — their impact on aquatic life. Nature has learned that landmark regulations intended to clean Europe’s waterways of pharmaceuticals are likely to be dead on arrival when they reach a key vote …

Panel Recommends 10-year Moratorium on Bt Crop Trial

A panel of scientists set up on the orders of the Supreme Court has recommended a 10-year moratorium on field trials of all genetically modified or Bt food crops. The six-member panel of technical experts came to this conclusion on the basis of the overall status of food safety evaluation …

Bar GM food crops, says parliamentary panel

‘Probe how Bt brinjal seed was allowed to be commercialised’ In a major setback to the proponents of genetically modified technology in farm crops, the Parliamentary Committee on Agriculture on Thursday asked the government to stop all field trials and sought a bar on GM food crops (such as Bt. …

State of the environment Maldives 2011

The State of the environment Maldives 2011 report addresses the objective of providing an analytical overview of state of the environment focusing on 10 key environmental challenges confronting today. New issues including energy, chemical and toxicology and environmental governance have been included in this report widening the information and data, …

Obesogens: An environmental link to obesity

Obesity has risen steadily in the United States over the past 150 years, with a marked uptick in recent decades. In the United States today more than 35% of adults and nearly 17% of children aged 2–19 years are obese. Obesity plagues people not just in the United States but …

Health effects of black carbon

This report presents the results of a systematic review of evidence of the health effects of black carbon (BC). Short-term epidemiological studies provide sufficient evidence of an association of daily variations in BC concentrations with short-term changes in health (all-cause and cardiovascular mortality, and cardiopulmonary hospital admissions). Cohort studies provide …

Safety evaluation of certain contaminants in food

The detailed monographs in this volume summarize the technical, analytical, dietary exposure and toxicological data on a number of contaminants in food: acrylamide, arsenic, deoxydivalenol, furan, mercury and perchlorate. This volume and others in the WHO Food Additives series contain information that is useful to those who produce and use …

Confronting a toxic blowback from the electronics trade

China has been accepting vast quantities of discarded televisions, computers, printers, and other equipment from abroad since the early 1990s. E-waste processing, a burgeoning cabin industry in coastal parts of China, may end up dwarfing other examples of contamination, scientists argued at a symposium. The roster of substances liberated during …
