Published Popular sport fish are behaviorally impaired from exposure to crude oil, study finds
(via sciencedaily.com) New research has confirmed that a popular sport fish exposed to sublethal levels of crude oil and released back into the wild exhibits altered behavior, decreased survival, and reduced spawning.
Published Grimy windows could be harboring toxic pollutants
(via sciencedaily.com) Dirty windows can harbor potentially harmful pollutants under protective films of fatty acids from cooking emissions -- and these can hang around over long periods of time.
Published Bigger plants don't always equal more nutritious ones
(via sciencedaily.com) While increased carbon dioxide levels in the atmosphere encourage plant growth, they also reduce the nutritional value of plants, which can have a larger impact on nutrition and food safety worldwide. Researchers have discovered a new way plants are adapting to the changing climate -- information that can be used to help plants grow strong while also maintaining their nutritional value.
Published Environmental scientists develop a method to turn hazardous acidic industrial wastewater into valuable resources
(via sciencedaily.com) Environmental scientists have developed a circular process for eliminating the risk posed by phosphoric acid plant wastewater. The process turns the environmentally toxic wastewater into clean water while recovering valuable acids. Phosphoric acid is the main ingredient in industrial fertilizers, a massive industry worldwide.
Published Climate change is affecting drinking water quality
(via sciencedaily.com) The water stored in reservoirs ensures our supply of drinking water. Good water quality is therefore important -- but is at significant risk due to climate change. In a model study of the Rappbode reservoir in the Harz region, a research team demonstrated how the climate-related disappearance of forests in the catchment area for Germany's largest drinking water reservoir can affect water quality. The problem of such indirect consequences of climate change is seriously underestimated, the scientists warn. Water quality is of critical importance, especially for drinking water reservoirs, as subsequent treatment in the waterworks must continually meet high standards.
Published Mirror image molecules reveal drought stress in forests
(via sciencedaily.com) Worldwide, plants emit about 100 million tons of monoterpenes into the atmosphere each year. These volatile organic molecules include many fragrances such as the molecule pinene -- known for its pine fresh scent. Since these molecules are highly reactive and can form tiny aerosol particles that can grow into nuclei for clouds droplets, natural emissions play an important role in our climate. Therefore, it is important for climate predictions to know how monoterpene emissions will change as temperatures rise.
Published Smoke from the Black Summer wildfires in Australia impacted the climate and high altitude winds of the southern hemisphere for more than a year and a half
(via sciencedaily.com) The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached high air layers as in the previous record wildfires in Canada during summer 2017. Research now reveals the climate impact of these huge fires: Smoke particles with a total mass of around one million tonnes spread across the southern hemisphere and affected the climate for about one and a half years by warming the upper atmosphere and cooling the lower atmosphere close to Earth's surface.
Published People generate their own oxidation field and change the indoor air chemistry around them
(via sciencedaily.com) High levels of hydroxyl radicals (OH) can be generated indoors, simply due to the presence of people and ozone.
Published Global analysis identifies at-risk forests
(via sciencedaily.com) Researchers quantify the risk to forests from climate change along three dimensions: carbon storage, biodiversity and forest loss from disturbance, such as fire or drought. The results show forests in some regions experiencing clear and consistent risks. In other regions, the risk profile is less clear, because different approaches that account for disparate aspects of climate risk yield diverging answers.
Published Pretreating soil with ethanol protects plants from drought, study finds
(via sciencedaily.com) Ethanol can help plants survive in times of drought says a new study. Adding ethanol to soil allows plants, including rice and wheat, to thrive after two weeks without any water. As ethanol is safe, cheap, and widely available, this finding offers a practical way to increase food production all over the world when water is scarce, without the need for costly, time-consuming, and sometimes controversial production of genetically modified plants.
Published Scientists develop new method to assess ozone layer recovery
(via sciencedaily.com) Researchers have developed a new method for assessing the impacts of ozone-destroying substances that threaten the recovery of the ozone layer.
Published Large regional differences in agricultural adaptation to future climate change in Europe
(via sciencedaily.com) Marked differences in how climate change will affect different parts of Europe require further focus and political attention if European agriculture is to adapt to future climatic conditions, say researchers.
Published Sulfur shortage: A potential resource crisis looming as the world decarbonizes
(via sciencedaily.com) A new study highlights that global demand for sulfuric acid is set to rise significantly from '246 to 400 million tons' by 2040 -- a result of more intensive agriculture and the world moving away from fossil fuels. A projected shortage of sulfuric acid, a crucial chemical in our modern industrial society, could stifle green technology advancement and threaten global food security, according to a new study.
Published Which animals can best withstand climate change?
(via sciencedaily.com) A new study investigates how different mammals react to climate change. Animals that live for a long time and/or produce less offspring -- like bears and bison -- are more resilient than small animals with a short life -- like mice and lemmings.
Published What happens to the waste after an oil spill clean up?
(via sciencedaily.com) Images of damaged coastlines, oily sheens, containment booms and endangered wildlife are part of every offshore oil spill. And while a response team arrives and the clean up gets underway, researchers are now exploring how to effectively handle the waste created from that spill.
Published Oil spill cleanup workers more likely to have asthma symptoms
(via sciencedaily.com) Researchers from the Gulf Long-term Follow-up Study (GuLF STUDY) found that workers involved in cleaning up the nation's largest oil spill were 60% more likely than those who did not work on the cleanup to be diagnosed with asthma or experience asthma symptoms one to three years after the spill.
Published Extreme heat and drought events require more systematic risk assessment
(via sciencedaily.com) Original source Simultaneous extreme heat and drought events have consequences in a variety of areas -- for example the economy, health and food production. In addition, due to complex socio-economic connections, such extreme events can cause knock-on effects, researchers have shown. More systematic risk assessments are needed to make affected regions more resilient.
Published How calcium ions get into the cellular power stations of plants
(via sciencedaily.com) Calcium is a very special nutrient. In the cells of most living beings calcium ions function as so-called second messengers to transmit important signals. The same applies equally to animal, plant and fungal cells.
Published More wolves, beavers needed as part of improving western United States habitats
(via sciencedaily.com) Original source Scientists are proposing management changes on western federal lands that they say would result in more wolves and beavers and would re-establish ecological processes.
Published New Antarctic study shows levels of 'forever chemicals' reaching the remote continent have been increasing
(via sciencedaily.com) New evidence from Antarctica shows that toxic 'fluorinated forever chemicals' have increased markedly in the remote environment in recent decades and scientists believe CFC-replacements could be among likely sources.
