Wildfire smoke is unraveling decades of air quality gains

2.5 from wildfire smoke has increased in much of the US, particularly in Western states, but some areas in the South and East have seen modest declines. This map shows the decadal change in smoke PM2.5, meaning the difference in daily average smoke PM2.5 during 2006−2010 compared to 2016−2020. Credit: Childs et al. 2022, Environmental … Read more

Climate change is affecting drinking water quality

The Rappbode reservoir in the Harz region is surrounded by forests and is the largest drinking water reservoir in Germany. Credit: André Künzelmann/UFZ Heat waves, drought, floods, forest fires—the consequences of climate change are increasing and are changing our environment. A prime example is the countryside in the catchment area for the Rappbode reservoir in … Read more

Adding fungal enzymes to dairy cow rations boosts milk output and quality

This 10-week study involved 48 Holstein cows at the Penn State Dairy Teaching and Research Center. Some were fed rations supplemented with an enzyme preparation extracted from a mixed fungal culture, and researchers then evaluated the cows’ lactational performance, metabolism and digestion.

Scientists recover collapsed clam population and water quality in Shinnecock Bay

Credit: Unsplash/CC0 Public Domain Scientists from Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS) announced the culmination of a decade of science in a paper published in Frontiers in Marine Science, which describes a novel restoration approach used in Shinnecock Bay that has led to a 1,700% increase in the landings and densities … Read more

Air quality can be better for active commuters than drivers, research shows

Researchers measured the air quality experienced during different modes of commute in Leicester over a 16-week period. Credit: Leicester City Council New Leicester research has found that people who commute by car can be subject to higher levels of harmful gases than those who walk or cycle to work. The study, conducted by researchers at … Read more

Pollution from California’s 2020 wildfires likely offset decades of air quality gains

Credit: CC0 Public Domain It was a nightmare fire season that California won’t soon forget. As more than 9,000 wildfires raged across the landscape, a canopy of smoke shrouded much of the state and drifted as far away as Boston. All told, more than 4.3 million acres would be incinerated and more than 30 people … Read more

DOI: 10.1016/j.cell.2022.04.016 In biology, getting rid of stuff can be just as important as making it. A buildup of cells, proteins, or other molecules that are no longer needed can cause problems, so living things have evolved several ways to clean house. A prime … Read more

Natural sources of air pollution exceed air quality guidelines in many regions

–3, citing global health considerations. We explore if this guideline is attainable across different regions of the world using a series of model sensitivity simulations for 2019. Our results indicate that >90% of the global population is exposed to PM2.5 concentrations that exceed the 5 μg m –3 guideline and that only a few sparsely … Read more
