More than 200 scientists from 38 countries spoke with one voice today, calling for curbs on the global production and use of a class of chemicals found in hundreds of grease- and water-resistant industrial and consumer products. To avoid long-term harm to the environment and human health,nations should act now to limit use of the toxic compounds, which can persist for long periods in the environment, the scientists conclude in a statement appearing in Environmental Health Perspectives. Industry groups, however, say currently used versions of the chemicals are safe.
