More Fukushima Question and Answer: Why don’t you measure contamination in marine algae?

By Jay T. Cullen

Diatoms under the microscope. Important marine algae that form the base of the food web in oceanic environments. From http://www.nsf.gov/news/news_images.jsp?cntn_id=128913&org=NSF


The purpose of this post is to address common questions related to Fukushima monitoring efforts being conducted by the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) network in the northeast Pacific Ocean and coastal waters of Canada. This diary continues a series aimed to report the results of scientific research into the impact of the Fukushima disaster on the environment. I am asked routinely why we do not measure contamination in marine microalgae, the base of the marine foodweb, given that they concentrate radionuclide contamination from Fukushima found in seawater into their cells as they grow. The extremely low levels of contamination found from Fukushima in the northeast Pacific Ocean combined with the very small amounts of microalgae present in oceanic waters make such monitoring logistically infeasible. Follow below the fold for the detailed answer. Continue reading More Fukushima Question and Answer: Why don’t you measure contamination in marine algae?
