A global taskforce of 174 scientists from leading research centers across 28 countries studied the link between mixtures of commonly encountered chemicals and the development of cancer. The study selected 85 chemicals not considered carcinogenic to humans and found 50 supported key cancer-related mechanisms at exposures found in the environment today. More:

In a review of various agricultural chemicals, IARC's specialist panel said it had decided to classify lindane as "carcinogenic to humans" in its Group 1 category, DDT as "probably carcinogenic to humans" in its Group 2A class, and the herbicide 2,4-D as "possibly carcinogenic to humans" in its Group 2B.

Manufacturers use hundreds of substances to produce clothing that don’t show up on clothing labels. And many of these are hazardous to the environment and to human health. Chemicals of particular concern include highly fluorinated compounds used to make durable waterproof finishes, such as those on rain jackets.More:

What do a pizza box, a polar bear and you have in common? - All carry a kind of industrial toxicant called poly- and perfluoroalkyl substances, or PFASs, that do two things: They make life convenient, and they also appear to increase the risk of cancer.

Perfluorinated compounds (PFCs) pose significant environmental concerns due to their stability and bioaccumulation in humans and animals. Current methods for extraction and measurement of PFCs require relatively large volumes of blood samples, not suitable for frequent blood sampling and biomonitoring. A new microassay for analyzing PFCs in small volumes (less than five microliters) of blood has been developed. More:

USA - One of the few shining stars of the nation’s economy, the $812-billion chemistry business, is working with Congress to pass a law that would actually give the federal government more authority to regulate chemicals. An industry that has spent the past 40 or so years operating under a loosely defined “chemical regulatory system” in the U.S. Toxic Substances Control Act (TSCA) has decided it’s time to bring U.S. chemical regulations into the 21st century.

In recent decades, many common migratory songbirds have declined in population. Several factors could explain this drop-off, including habitat loss, climate change, feline predators, and wind turbines. But a new study finds that polychlorinated biphenyls (PCBs), toxic industrial pollutants, may share some of the blame by affecting birds’ ability to migrate. More:

A Cooper's hawk discovered near a waste transfer station in greater Vancouver, Canada, is believed to be the most polluted wild bird ever discovered. In fact, it was so contaminated with flame retardant chemicals that it was "flameproof", according to a McGill University news release. Publishing in the journal Science of the Total Environment, the researchers compared levels of PBDEs in the liver fat of 13 birds of prey across Vancouver. More:

Greenland’s polar bears have a thyroid problem. Their endocrine systems, too, are being disrupted. Kristin Møller Gabrielsen of the Norwegian University of Science and Technology and colleagues report in the journal Environmental Research that they examined the liver, muscle and kidney tissues taken from seven polar bears. They also analysed the effect of more than 50 contaminants in plasma samples from Ursus maritimus. More:

Toxins are now a major contributor to, and in some cases the cause of, virtually all chronic diseases. That's what Joseph E. Pizzorno, former advisor to President Clinton on complementary and alternative medicines, says. "I have become convinced that the toxic load in modern civilisation is now probably even more important than nutritional deficiencies in terms of causing diseases in our patients," says Pizzorno.

Pesticides bring major benefits to modern agriculture, keeping dangerous bugs and fungi and pathogens at bay. But what about risks? Like any chemicals pesticides can be bad for human health and ecosystems. It’s often tough, however, to get a clear picture of the full array of problems a pesticide may cause. A new “meta-analysis” — a review of existing scientific studies — provides some answers, but raises even more questions in the process. More:
