Canadian Food Inspection Agency Report on Arsenic Levels in Beverages, Food
A Report by the Canadian Food Inspection Agency examines the analysis of beverage and food samples collected from Canadian retail stores for levels of inorganic and organic arsenic. The Report concludes that "the levels of arsenic in the products tested in this survey were not considered to pose a concern to human health."
Elevated Levels of Arsenic Found in Epping, NH Well Water
Water testing in Epping, NH has found elevated levels of arsenic in recent samples taken from the new town well. According to a story in the NH Union Leader, the contamination is not considered an emergency by the town, and an arsenic removal system will be installed in the future.
Water Management May Reduce Effects of Climate Change on Rice Production and Arsenic Uptake by Rice Plants in Asia
According to Dennis Wichelns, Senior Fellow of Thailand-Based Stockholm Environment Institute, adapting the practice of "de-watering" by farmers in Asia will reduce the effects of climate change on rice production, as well reduce arsenic uptake by rice plants. "De-watering" involves removing water from rice paddies at least once during the growing season. See full story.
FDA Finds Excessive Amounts of Arsenic in Apple Juice from Yakima Valley Processor
The Seattle Times reports that the FDA has found almost nine times the allowed limit in samples of apple juice taken from a Yakima Valley, WA processor. Prolonged exposure to high levels of inorganic arsenic has been associated with a number of health conditions.

Research conducted by Tulane University geochemistry professor Karen Johannesson has found the presence of arsenic in parts of rural LA to be at least 10 times higher than EPA standards of less than 10 parts per billion. While the amount is significantly less than what she and her colleagues found in the Bengal Basin of India , she says that it is alarming nonetheless, as arsenic is associated with an array of health issues. Dr. Johannesson's team's paper on arsenic in shallow groundwater from the Napoleonville, LA site recently was accepted for publication in the Journal of Hydrology: Regional Studies.

Investigators Find High Concentrations of Toxic Metals in Whales
Investigations led by the University of Aberdeen, in collaboration with the Scottish Marine Animal Stranding Scheme, have shown that a pod of beached whales had high concentrations of mercury and cadmium, including in their brains.
