Andrea Dietrich and Amanda Sain of Virginia Tech’s Via Department of Civil and Environmental Engineering estimated that 50 percent of the population taste threshold for manganese II in water, the simplest ionic manganese oxide, to be more than 1000 times the current EPA allowable level. Their findings appear in the Journal of the American Water Works Association, and they are now looking into possible secondary pollution issues with the release of manganese in air through its use in humidifiers.
In one year, India’s ozone pollution damaged millions of tons of the country’s major crops, causing losses of more than a billion dollars and destroying enough food to feed tens of millions of people living below the poverty line.
The Environmental Protection Agency has won a U.S. Supreme Court ruling, which will allow it to progress with its strategy for reducing pollution generated by coal-fired power plants in many states. Scientists have found that this endeavor could help save many lives.
Researchers from different universities studied the potential health and economic benefits of plans proposed on the control of air pollution in over-polluted regions of China. According to them, the costs related to the fatality and disability caused by air pollution came down by 50% in Taiyuan, China’s Shanxi Province capital between 2001 and 2010. The result of the study is published online in the Environment International journal.
A Commission led by Ohio State University Professor, William Martin and Liverpool School of Tropical Medicine Professor, Stephen Gordon, studied the health effects of indoor air pollution. The study, published in the journal - The Lancet Respiratory Medicine, estimated that solid fuels like coal, charcoal or wood are being used for heating, cooking and lighting purposes by one-third of the human population, globally.
A new model created by the University of New South Wales researchers could be helpful in determining the countries to be blamed for causing the ocean garbage patch, a gyre of floating rubbish.
A new study reports that an expansion of marine protected areas is needed to protect fish species that perform key ecological functions. According to investigators from the Wildlife Conservation Society and other organizations, previous efforts at protecting fish have focused on saving the largest numbers of species, often at the expense of those species that provide key and difficult-to-replace ecological functions.
A number of leading international researchers, amongst others from the National Food Institute, Technical University of Denmark, recommend that fluorochemicals are only used where they are absolutely essential, until better methods exist to measure the chemicals and more is known about their potentially harmful effects. The recommendation appears in the Helsingør Statement following an international conference.
The Ames test, a widely used method to determine whether a chemical has the potential to cause cancer, has been successfully adapted for use with cigarette smoke and other complex aerosols.
Unregulated trash burning around the globe is pumping far more pollution into the atmosphere than shown by official records. A new study led by the National Center for Atmospheric Research estimates that more than 40 percent of the world’s garbage is burned in such fires, emitting gases and particles that can substantially affect human health and climate change.
