Combining experimental and computer chemistry, scientists find the conditions to break carbon-hydrogen bonds at low temperature with cheap titanium in place of rare metals.
The US banned PCBs nearly four decades ago, but they persist in the environment and have been found in animals and humans since then. Now researchers report in ACS' journal Environmental Science & Technology that concentrations of airborne PCBs inside schools could result in some students inhaling the compounds at higher levels than they would consume through their diets. Exposure through both are lower than set limits, but cumulative amounts, researchers caution, could be concerning.
NASA-NOAA's Suomi NPP satellite captured an image of Dora at peak strength late on June 26 before it started moving over cooler waters that began sapping its power.
But the woodrats' unique adaptation that allows them to break down creosote toxins may be in jeopardy if temperatures continue to rise, according to University of Utah researchers. Their new study in Molecular Ecology explains why: Livers of mammals (including us) may be less efficient at breaking down toxins at higher temperatures.
Kansas State University researchers published a study in Frontiers in Environmental Science that showed Manganese relates differently than its cancer-causing cousin, arsenic, to dissolved organic matter in groundwater. Researchers say more studies are need to understand the relationship.
A warming climate is not just melting the Arctic's sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country's waters, says a new study.
The technique enables the detection of gases, such as atmospheric pollutants, present in extremely small quantities that are otherwise difficult or impossible to detect.
The airborne dust carried in sand storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.
Recent increases in an unregulated ozone-depleting substance, could delay recovery of Antarctic ozone levels by 5-30 years, depending on emissions scenarios. The findings, published in Nature Communications, suggest that a previously ignored chemical called dichloromethane may now be contributing to ozone depletion.
Remote sensing technologies, using satellite and aerial data, could revolutionize the management of the oil palm industry, bringing both business and environmental benefits, say environmental experts writing in the journal Geo-spatial Information Science.
