Nitrous oxide (N2O) follows carbon dioxide and methane as the third-most significant greenhouse gas. It is a nearly 300 times powerful warming agent per unit mass compared to carbon dioxide. Microbial activity is the source for the production of nitrous oxide in soils.
Charles Darwin University (CDU) is joining with The American Chemistry Council’s (ACC) North American Flame Retardant Alliance (NAFRA) and the United Arab Emirates University (UAEU) in Al Ain to develop new processes for recovering and recycling bromine and antimony from flame-retarded plastics.
New data released today by Aeternum, a provider of low cost, unplugged sensors designed to accurately monitor air quality, finds that levels of the air pollutant nitrogen dioxide increased by nearly a third within a mile of COP26 in Glasgow last month.
A research team from Canada and Germany has identified a novel kind of earthquake signal in the vicinity of injection wells characterized by hybrid-frequency waveforms (EHWs).
According to the World Health Organization, air pollution is the greatest health hazard globally, causing over 4.2 million deaths per year.
After reaching the atmosphere, methane causes more than 80 times the warming power of carbon dioxide over the first 20 years. While CO2 has a longer-lasting effect, methane sets the pace in the near term. At least 25% of today’s warming is thought to be led by anthropogenic methane production.
This study is led by Professor Nianzhi Jiao (State Key Laboratory for Marine Environmental Science, Institute of Marine Microbes and Ecospheres, College of Ocean and Earth Sciences, Xiamen University), Professor Yao Zhang, and Dr. Zongqing Lv. In previous study, Jiao et al. found that the use of chemical oxygen demand (COD) in natural water bodies as a monitoring indicator of organic matter is misleading, and could judge refractory dissolved organic matter (RDOM) in water bodies as pollutants.
ETH scientists investigated the global plastics value chain and revealed that the effect of plastics on health and climate is bigger than formerly believed because of the increased use of coal for electricity, process heat, and as a raw material in production.
Electric vehicles are so quiet and tend to reduce sound pollution. However, they can be of safety concern, especially for the visually impaired. To tackle this, many governments have commissioned the addition of artificial sounds to electric vehicles.
Microplastics are all over the place, even in the most remote regions of the world. Where do these minute pieces of plastic originate from? Scientists from the University of Basel and the Alfred-Wegener Institute have demonstrated that it requires precise analysis to respond to this question.
