After nearly 30 years of delays caused by pressure from chemicals and defense industries, the US Environmental Protection Agency (EPA) is moving forward on setting a safety limit for exposure to dioxin, a ubiquitous, highly toxic and carcinogenic chemical that people of all ages ingest daily with their food – starting at a mother's breast.

The Hallmarks of Cancer are the ten characteristics that differentiate a cancer cell from a normal cell. Over the course of a year, science translator Dr. Buddhini Samarasinghe tackled each of the the ten Hallmarks of Cancer in a guest blog series for Scientific American. The blogs break down the basic biology of each Hallmark and what happens when the system breaks down. It is important to

Smoggy air costs Californians more than $521 million a year — a price paid in hundreds of trips to the emergency room, thousands of hospital admissions and millions of missed school days, according to an Environmental Working Group analysis of state data.

The story of Anniston is a cautionary tale. Monsanto's internal documents, many of which are being posted here for the first time for the world to finally see, uncover a shocking story of corporate deception and dangerous secrets.

In the first nationwide tests for brominated fire retardants in house dust, the Environmental Working Group (EWG) found unexpectedly high levels of these neurotoxic chemicals in every home sampled. The average level of brominated fire retardants measured in dust from nine homes was more than 4,600 parts per billion (ppb). A tenth sample, collected in a home where products with fire retardants were

Consumers instantly recognize them as household miracles of modern chemistry, a family of substances that keeps food from sticking to pots and pans, repels stains on furniture and rugs, and makes the rain roll off raincoats. But in the past 5 years, the multi-billion dollar “perfluorochemical” industry has emerged as a regulatory priority for scientists and officials at the U.S. Environmental

More than 45 million Americans in thousands of communities were served drinking water during 1994-1995 that was polluted with fecal matter, parasites, disease causing microbes, radiation, pesticides, toxic chemicals, and lead at levels that violated health standards established under the federal Safe Drinking Water Act. More than 18,500 public water supplies reported at least one violation of a
