Sun cream sheds titanium dioxide in the sea, French study suggests

Swimmers' sun creams deposit titanium dioxide nanoparticles into the sea, where their protective coatings may be washed away, according to a French study. Last year, a team led by Dr Jérôme Labille from Aix-Marseille Université analysed titanium dioxide levels in the water off three French beaches. Their social scientist colleagues counted the number of beach users, asked ...

Towards the ultimate model of water

Water is essential to life as we know it; from its unusual density maximum which preserves freshwater ecosystems by ensuring that ponds freeze from the top down during winter, to its hydrogen bonds which shape proteins and the DNA double helix. But while water (in its liquid, solid and vapour forms) is one of the most common substances on Earth, many of its life-sustaining properties remain a ...

The right to water

The problem is real. The United Nations forecasts that by 2030, nearly half of the world’s population will be living in areas of 'high water stress, and climate change is compounding the problem according to a UN report released to coincide with the Istanbul conference. Global warming is causing droughts in some areas and floods in others. In Africa alone, between 75 million and 250 million ...

The world’s first model for engineered nanoparticles in surface waters

Researchers of Wageningen University provide the world’s first spatiotemporally explicit model that simulates the behaviour and fate of engineered nanoparticles (ENPs) in surface waters. Wageningen researcher Bart Koelmans: “This is important in order to assure safe nanotechnology. We do need to have an assessment of the risks of ENPs to man and the environment.” ...

Tacoma group offers role model for providing safe water

No one wants to deny a thirsty child a glass of clean water to drink - especially not in the United States, where clean water flows freely from our taps, our drinking fountains and our Brita filters. But around the world, three million people die every year from waterborne diseases caused by unclean drinking water and 90 percent of them are children under the age of 5. Although this problem may ...

New model simulates US groundwater and surface water interactions

A new model to simulate groundwater and surface water interactions has been released by the U.S. Geological Survey (USGS). The groundwater and surface water FLOW (GSFLOW) model simultaneously accounts for climatic conditions, runoff across the land surface, subsurface flow and storage, and the connections among terrestrial systems, streams, lakes, wetlands, and ground water. 'GSFLOW can be used ...

Water security in an uncertain world

Policymakers must find flexible plans to ensure water security despite the uncertainties of climate change, says climate scientist Mark New. Much of the developing world is dependent on rainfall, snow or ice for its natural water supplies, so researchers and policymakers are concerned about how climate change will affect water security. Long-term water availability is largely determined by the ...
