Studies have shown that a blood level of 10 mcg of lead per deciliter of blood is associated with potentially irreversible harm, although recent studies have shown that as little as 5 mcg/dL can also be dangerous. By extrapolating from their data, researchers estimated that if a population of children under age 4 was routinely exposed to Indian spices or ceremonial powders, the additional ingestion of lead would lead to a threefold increase - from 0.8% to 2.8% - in the percentage of children with a blood level of lead over 10 mcg/dL. "Our message is to say, Be aware of these...
Currently the Food and Drug Administration, which oversees the safety of food products imported into the U.S., does not have specific guidelines for screening lead in dried products like spices. That's because the FDA feels there is no safe level of lead in dried products, since studies have not yet established that lead exposure doesn't lead to adverse health effects...
...agency has different thresholds for acceptable lead levels depending on the product and how it is to be used, says FDA spokesperson Ira Allen. For example, in 2006 the agency lowered its acceptable level of lead in candy, which children are likely to eat in large amounts. The FDA also reaffirmed its position that paints used in candy labels should be entirely lead-free, or they would be in violation of the Federal Food, Drug and Cosmetic Act.

With 270 million Americans and 4 billion people around the world using cell phones - and more signing up every day - a strong link between mobiles and cancer could have major public-health implications. As cell phones make and take calls, they emit low-level radio-frequency (RF) radiation. Stronger than FM radio signals, these RF waves are still a billionth the intensity of known carcinogenic radiation like X-rays. (See pictures from an X-ray studio...
