The July 2011 issue of IEAM features a series of commentaries that were solicited as a result of the recent nuclear accident in Japan that occurred as a result of a magnitude 9.0 earthquake and subsequent tsunami on 10 March 2011. The series, titled “Challenges Posed by Radiation and Radionuclide Releases to the Environment,” consists of 16 invited commentaries that address various aspects of environmental chemistry, bioaccumulation, food web transfer, toxicity to a variety of biota, aspects of environmental policy, and risk assessment, management, and communication. Readers can access these commentaries for free on our web site through the end of December 2011. Join us as we chat with Igor Linkov and Brad Sample about the series and gain further insight on related topics.
