“Rising global temperatures and changing human actions will significantly affect the behavior and distribution of mercury worldwide, according to a recent article by the U.S. Geological Survey and Harvard University. …
“Several seemingly unconnected aspects of climate change are expected to affect mercury at the global scale, according to the article.
“Japanese Prime Minister Shinzo Abe ordered the operator of the country’s crippled nuclear power plant on Thursday to scrap all six reactors at the site instead of just four already slated for decommissioning and to concentrate on tackling pressing issues like leaks of radioactive water.”
“Heal the Bay has received many questions from concerned residents in Southern California about potential health and environmental impacts along the California coast that may result from the Fukushima nuclear power plant disaster in Japan. Here is our perspective about possible radiation dangers, gleaned by consulting the scientific community:
“What is the source of potential radiation?
“… For the past two and a half years, the Tokyo Electric Power Company (Tepco) has been trying to cool the three reactors impacted by the tsunami.
“Japan’s nuclear watchdog is considering raising the danger level at the Fukushima plant to ’serious.’ That’s after 300 tons of contaminated water leaked from a holding tank there — some of it possibly reaching the Pacific.”
“Since its founding, [Scott] Harrison’s charity [charity: water] has worked in 20 countries, but it has spent more money drilling wells and setting up hand pumps in Tigray than anywhere else — projected to be some $27 million by the end of this year. By trying to ensure that the region’s entire rural population, some four million people, has access to clean water, Harrison hopes to be able to offer proof (a word he loves) that the global water crisis is solvable.
“The Santa Cruz River watershed, located on the Arizona-Sonora portion of the U.S.-Mexico border, depends for its perennial flow on an international treatment plant that treats wastewater on both sides of the border before discharging it into the river in Arizona. This treated wastewater has great value for nearby wildlife and ecosystem managers, property owners and communities. Now, USGS science has helped to quantify this value for the benefit of binational water policy makers and other stakeholders.
“The stricken nuclear power plant at Fukushima has probably been leaking contaminated water into the ocean for two years, ever since an earthquake and tsunami badly damaged the plant, Japan’s chief nuclear regulator said on Wednesday.”
“Japan’s nuclear regulator says radioactive water from the crippled Fukushima power plant is probably leaking into the Pacific Ocean, a problem long suspected by experts but denied by the plant’s operator.”
“Arsenic is one dangerous pollutant that can occur naturally (though it also can be a byproduct of pesticide use or certain kinds of mining), usually ingested via water. In Nepal and other impoverished areas of Asia where arsenic levels are high, low-tech water filters make a huge difference — a jar filled with rusty nails and sand.
“Tokyo Electric Power, the operator of the stricken nuclear power plant at Fukushima, said Wednesday that it had detected high levels of radioactive strontium in groundwater at the plant, raising concerns that its storage tanks are leaking contaminated water, possibly into the ocean.”
“London – Austria’s alpine lakes are warming, and that’s bad news for the region’s fish and economy, according to new research in the journal Hydrobiologia. … On the other side of the globe, Peter Moyle, a biologist at the University of California, Davis, has been more concerned with the freshwater fish that make their homes in or migrate to California’s rivers and lakes.”
“A growing demand for milk and cheese in China has the potential to bring California’s beleaguered dairy industry back to life – and with it, renewed concern about its damaging effects on the environment.”
“Although water has figured prominently in the U.N. development agenda for decades, the world is at a critical juncture as the Rio+20 Sustainable Development Goals take shape over the coming 12 months.”
“Nearly 1.5 miles beneath Earth’s surface in Canada, scientists have found pockets of water that have been isolated from the outside world for more than 1 billion years.
The ancient water, trapped in thin fissures in granite-like rock, has been bubbling up from a zinc and copper mine for decades in Timmins, Ontario. Only recently have scientists been able to calculate the age of this water and determine that it is the oldest ever discovered — possibly as old as 2.6 billion years, when Earth was less than half its current age.
