New research shows the Ganges River - with the combined flows of the Brahmaputra and Meghna rivers - could be responsible for up to 3 billion microplastic particles entering the Bay of Bengal every day.
By 2050, most people on Earth will live downstream of tens of thousands of large dams built in the 20th century, many of them already operating at or beyond their design life, according to a UN University analysis.
Using water samples and environmental data gathered over 48 hours or less, Stanford engineers develop a new predictive technique for forecasting coastal water quality, a critical step in protecting public health and the ocean economy.
One of Brazil's worst environmental disasters - a dam collapse that also killed more than 200 people - could have been foreseen with latest satellite radar imaging technique, according to a new study by the University of Nottingham and Durham University.
In a paper published in NANO, researchers from Hubei, China discuss the top-down and bottom-up strategies for the synthesis of Graphene quantum dots (GQDs). The respective advantages and disadvantages of these methods are summarized. With regard to some important or novel ones, the mechanisms are proposed for reference. In addition, the application of GQDs in biosensors is highlighted in detail.
A recent McGill study published in Environmental Science and Technology finds that annual methane emissions from abandoned oil and gas (AOG) wells in Canada and the US have been greatly underestimated - by as much as 150% in Canada, and by 20% in the US. Indeed, the research suggests that methane gas emissions from AOG wells are currently the 10th and 11th largest sources of anthropogenic methane emission in the US and Canada, respectively.
Nature's Communications Earth and Environment just published a paper by a group of researchers led by Damon Matthews in which they present a new framework for calculating the remaining carbon budget that is able to generate a much narrower estimate and its uncertainty. The researchers estimate that between 230 and 440 billion more tonnes of CO2 from 2020 onwards can be emitted into the atmosphere and still provide a reasonable chance of limiting global warming to 1.5°C.
The Messina Strait, a submarine bridge separating the island of Sicily from the Italian Peninsula, is the area with the largest marine litter density worldwide -more than a million objects per square kilometre in some parts-, as reported in a new review paper published in the journal Environmental Research Letters.
'What goes in, must come out' is a familiar refrain. It is especially pertinent to the challenges facing UBC researchers who are investigating methods to remove chemicals and pharmaceuticals from public water systems. Cleaning products, organic dyes and pharmaceuticals are finding their ways into water bodies with wide-ranging negative implications to health and the environment, explains Dr. Mohammad Arjmand, an assistant professor of mechanical engineering at UBC Okanagan.
A research team from the Institut national de la recherche scientifique (INRS) has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source. The results of this research have been published in the Environmental Pollution journal.
