Examining the Fate of Fukushima Contaminants

Researchers deployed time-series sediment traps 115 kilometers southeast of the nuclear power plant at depths of 500 meters and 1,000 meters. The two traps began collecting samples on July 19, 2011—130 days after the March 11 earthquake and tsunami—and were recovered and reset annually.

An international research team reports results of a three-year study of sediment samples collected offshore from the Fukushima Daiichi Nuclear Power Plant in a new paper published August 18, 2015, in the American Chemical Society's journal, Environmental Science and Technology. The research aids in understanding what happens to Fukushima contaminants after they are buried on the seafloor off coastal Japan. Led by Ken Buesseler, a senior scientist and marine chemist at the Woods Hole Oceanographic Institution (WHOI)…

New Bunker Fuel Developed by Scientists

Scientists develop a cleaner fuel for cruise ships & other large vessels from ingredients in detergents, medicines. Scientists describe development of a new fuel mixture to ease the major air pollution and cost problems facing cruise ships, oil tankers and container ships which tend to burn the cheapest and most highly polluting form of diesel fuel. Their report was part of the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here this week. George N. Harakas, Ph.D. and colleagues from the Maine Maritime Academy and SeaChange Group LLC developed a fuel by adding two ingredients to low-sulfur diesel to produce "Bunker GreenTM" fuel, a member of the Eco-HybridTM family of fuels.

Ensolve Biosystems' Senior Scientist Receives Top Honor

Dr. Donald W. Kelemen, senior scientist of EnSolve Biosystems, has been selected as an honoree for the 2000 American Chemical Society's Industrial Innovation Awards Program. Dr. Kelemen is a co-founder of EnSolve Biosystems and played an instrumental role in the development of the PetroLiminator, the first biomechanical oily water separator for the marine industry. The PetroLiminator is a patented system that uses a combination of mechanical separation and bioremediation to treat bilge water so that it can be safely discharged overboard in environmentally sensitive waterways. Introduced in early 2000, the PetroLiminator has been type approved by the U.S. Coast Guard, IMO and Canadian authorities to meet international clean-water standards.

Study: Shipping Cited in Pollution-Related Deaths

While the international shipping industry already is under acute pressure to reduce emissions, a new study – which claims that worldwide 60,000 deaths each year are attributable to pollutions from ships – could help to increase public pressure further. The study, published in the American Chemical Society’s publication Environmental Science & Technology (ES&T) (DOI: 10.1021/es071686z) was produced by a team led by James Corbett of the University of Delaware and James Winebrake of the Rochester Institute of Technology, provide some of the first estimates of premature mortality from exposure to particulate matter, nitrogen oxides (NOx), and sulfate in global ship emissions.
