Fukushima's nuclear meltdown hasn't been the environmental calamity we feared


April 28th, 2021
It’s been ten years since the devastating 9.0 magnitude Tōhoku earthquake and its subsequent 46 foot-tall tsunami killed more than 18,000 people, obliterated entire towns, and crippled the Fukushima Daiichi nuclear power plant on Japan’s eastern coast. As the incident unfolded in March, 2011, the stricken power plant released massive amounts of cesium-137 into the surrounding environment (roughly 80 percent of the material running into the Pacific ocean) and continued to pour out around 30 gigabecquerel of cesium-137 and strontium-90 for the next two years. And, as of 2018, around 2 gigabecquerel of radioactive pollution still manages to escape the site daily.
Now, as a decommissioning project that is expected to take a generation to complete enters its second decade, Japan’s government announced a controversial decision regarding the site’s continued cleanup. The government reportedly has approved a plan to dump more than a million tons (~250 mil ....

"Development of a Bioavailability-Based Risk Assessment Framework for N" by Emily R. Garman, Christian E. Schlekat et al.


Abstract
Nickel laterite ore deposits are becoming increasingly important sources of Ni for the global marketplace and are found mainly in tropical and subtropical regions, including Indonesia, the Philippines, Papua New Guinea, Cuba, and New Caledonia. There are few legislatively derived standards or guidelines for the protection of aquatic life for Ni in many of these tropical regions, and bioavailability-based environmental risk assessment (ERA) approaches for metals have mainly been developed and tested in temperate regions, such as the United States and Europe. This paper reports on a multi-institutional, 5-y testing program to evaluate Ni exposure, effects, and risk characterization in the Southeast Asia and Melanesia (SEAM) region, which includes New Caledonia, Papua New Guinea, the Philippines, and Indonesia. Further, we have developed an approach to determine if the individual components of classical ERA, including effects assessments, exposure assessments, and risk c ....
