How aerosol scientists spread the word on the airborne transmission of COVID-19–and what it means for cleaning our indoor air.
Uranium Detected in Latinx Communities’ Water Systems
The unsafe contaminant levels could not be attributed to differences in regional geology, water source, or community size. Researchers suggest they are due to a failure of regulatory policy.
Pharmaceuticals Found in Rivers on All Continents
A quarter of 258 observed rivers had unsafe levels of at least one drug. The findings raise concerns about Earth’s aquatic life and the global threat of antimicrobial resistance.
Road Salts Linked to High Sodium Levels in Tap Water
Use of deicing agents may sometimes raise sodium levels in drinking water beyond healthy limits for people on salt-restricted diets.
Weighing the Benefits of Urban Greening
City communities may need to consider whether water absorption or cooling benefits are more important when designing urban greening.
Exposure to Low Levels of Air Pollution Increases COVID-19 Risk
Although causality has yet to be established, an Italian case study found that an increase in annual average exposure to PM2.5 was associated with a jump in the rate of COVID-19.
Remote Sensing Could Predict Well Water Quality After Floods
After a flood, most people rely on officials to test public water sources. Private well owners are on their own, with little data to guide testing and treatment. New research seeks to change that.
Cyanobacteria Blooms Exceed WHO Thresholds in Midwest Lakes
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
Los beneficios para la salud y el clima de reducir la contaminación del aire
En un nuevo estudio, investigadores aplicaron un modelo global del sistema Tierra para estimar los impactos de las reducciones de emisiones por sector.
