Ocean-friendly Seabin sucks up surrounding sea trash

The mounting plastic waste in the world's oceans has been the subject of of some pretty bold environmental undertakings, perhaps none more so than the Ocean Cleanup Project aiming to eradicate the Great Pacific Garbage Patch. The Seabin Project represents a smaller-scale approach, but it is noble in its aspirations all the same. Installation in ports and marinas sees this ocean-friendly trash can suck up the surrounding debris and even remove oil from the water.

Atmotube personal pollution monitor tracks air quality on the go

Life in many of today's big cities unfortunately brings with it exposure to dense particle pollution. As a result, urban residents from Beijing, China to Santiago, Chile face serious health risks, such as heart and lung disease and premature death. A new US-based startup has developed a pocket-sized pollution monitor it hopes will serve as a warning system, by constantly assessing the environment while the user is on the go and alerting them when air quality drops to unacceptable levels.

Claimed darkening of ice sheet could actually be down to aging satellite sensors

In recent years, satellite photos of Greenland's ice sheet have shown what appears to be a darkening of the ice's surface. A number of scientists have suggested that this could be due to settled soot particles from fossil fuel production and/or forest fires, and that their presence could result in accelerated melting of the ice. Now, however, researchers from Dartmouth College believe that the ice may still still be relatively clean, and that its darkness in the photos could just be due to faulty sensors on the satellites.

Smartphones may soon detect air pollution

According to the World Health Organization, nitrogen dioxide (NO2)-based air pollution contributes to over 7 million deaths per year – children and the elderly are particularly at risk. Thanks to research being carried out at Australia's RMIT University, however, it may soon be possible to receive early warnings of dangerous NO2 levels in the air around you … via a sensor in your smartphone.

New material created from orange peel cleans up mercury pollution

Since the beginning of the industrial age, mercury pollution has increased steadily in our environment, particularly in rivers and oceans. As a result, high-level predators in our waterways often contain very high levels of mercury, and eating fish containing this neurotoxin can lead to serious health issues. Now Australian scientists working at Flinders University have discovered a simple and efficient way to remove mercury from the environment by using a material made from recycled waste citrus peel.
