Bleached chopsticks warning issued

Oct 05 ,Medicine & Health


Taiwanese officials say they've found excessive levels of sulfur dioxide in some bamboo products, including disposable chopsticks and skewers.

The Taiwan Consumers' Foundation said people might be ingesting a substance that can cause osteoporosis, as well as serious allergic reactions, the Taipei Times reported Thursday. The newspaper noted there are no laws controlling the use of sulfur dioxide in bleaching and sanitizing bamboo products.

"The industry should make an effort to better sterilize their bamboo products," said National Taiwan University Professor Cheng Cheng-yung, a foundation member. "With a lower moisture content and vacuum packaging, there's no need to resort to sulfur dioxide as a sanitizer."

Other items the foundation said contain sulfur dioxide include bamboo dessert forks and coffee stirring sticks, the newspaper said.

In a bid to control greenhouse gas emissions linked to climate change, the European Union has been operating the world's first system to limit and to trade carbon dioxide. Despite its hasty adoption and somewhat rocky beginning three years ago, the EU "cap-and-trade" system has operated well and has had little or no negative impact on the overall EU economy, according to an MIT analysis.
Fuel cells: distant dream, but burning with promise
Some day, fuel cells may power your car and exhaust only water and perhaps carbon dioxide. More efficient and cleaner than an internal combustion engine, their emissions will be much lower. They may also run your home without the energy loss of power lines, or even power your laptop or cell phone. But not today or even tomorrow.

The Chaiten volcano now erupting in southern Chile is one of 200 to 300 volcanoes in the "Andean Arc" region of Chile, Peru, Ecuador and Columbia considered active by volcanologists, some of which lie in much more densely populated areas, said a University of Colorado at Boulder geologist who has studied Chaiten.
On the Energy Trail: Researchers Find New Details Following the Path of Solar Energy During Photosynthesis
Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. That’s the promise of artificial versions of photosynthesis, the process by which green plants have been converting solar energy into electrochemical energy for millions of years. To get there, however, scientists need a far better understanding of how Nature does it, starting with the harvesting of sunlight and the transporting of this energy to electrochemical reaction centers.

Sulfur dioxide may have helped maintain a warm early Mars
Sulfur dioxide (SO2) may have played a key role in the climate and geochemistry of early Mars, geoscientists at Harvard University and the Massachusetts Institute of Technology suggest in the Dec. 21 issue of the journal Science. Their hypothesis may resolve longstanding questions about evidence that the climate of the Red Planet was once much warmer than it is today.
