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.

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.
